Job Stories From Nashua, NH
High Radon Levels, Hudson, NH

A resident in Nashua, New Hampshire has been living in their house for almost a decade. Recently, their daughter tested her own home for radon water and had to install a radon system. This prompted the homeowner to test their own home for radon levels and the results showed an average of 30 pCi/L, which is considered high. As a result, they contacted EFS to have their home inspected and to design a radon mitigation system. Our Design Specialist, Nikki Burke, met with the homeowner and designed a system that had two extraction points to reduce the levels of radon inside the home. 

 

Our installation team created two extraction points and connected them with a radon pipe that was fed to the exterior of the house. On the outside of the house, we installed a radon fan and additional radon piping to draw radon from beneath the house and vent it above the house, preventing it from re-entering the house. 

 

Once the system was fully installed, we showed the homeowner the system and provided them with a charcoal radon test kit to verify that the levels had been lowered after the system had been running for about a week.

Geolock Installation, Nashua, NH

A homeowner in Nashua, New Hampshire had purchased their house 15 years ago. Over the years, they noticed some cracks in the foundation wall of their garage. They wanted to finish their basement but were worried that the foundation wall could collapse. They contacted EFS for a free inspection of their basement. Our Design Specialist, Peter Carstean, met with the homeowner and examined the cracks inside the garage. Peter determined that the cracks were caused by the foundation wall moving and recommended installing 5 Geolocks to stabilize it and 3 FlexiSpans to seal the cracks in the foundation.

 

Our installation team began by digging a trench in the yard, 10 feet from the foundation, running parallel to it for installing our Geolocks. The team marked out 5 spots on the foundation wall where they would install each anchor. Then, they drilled a small hole through the foundation and passed a threaded rod through the foundation, soil, and into the trench in the yard. After that, they attached a Geolock Anchor to either side of the rod and tightened each end to stabilize the foundation wall slowly. The system used leverage from the soil to stabilize and straighten the foundation wall. After tightening the Geolocks, the team installed the FlexiSpans over the cracks in the wall.

 

Once the project was complete, the team cleaned up the job site before doing a final walkthrough with the homeowner to show them what was installed. The homeowner was very pleased with the results of the project.

Concerns with Radon Inside their Home, Nashua, NH

A homeowner in Nashua, New Hampshire bought their house three years ago. They tested their home for radon and the levels were found to be around 8.1 pCi/L, which was higher than the recommended amount of 4.0 pCi/L. As a result, the homeowners contacted EFS to request a free inspection of their basement to determine if they could install a radon mitigation system to lower the radon levels. 

 

Our Design Specialist, Victor Tapia, met with the homeowner and inspected the basement. After examining the basement, Victor recommended installing a radon mitigation system with a single extraction point. 

 

Our installation team, led by Steve Dumais, started the installation process by using a core drill to create an extraction point. They then installed a 3" PVC pipe from the extraction point and connected it to the exterior of the home. On the exterior of the home, we installed our Radon Fan and secured the PVC pipe to the fan. After securing the radon pipe, we vented the system above the roofline of the home to ensure that radon air cannot re-enter the home. 

 

After the system was installed and operational, a radon test was left in the basement to ensure that the levels were brought down below the recommended 4.0 pCi/L. The homeowners were very satisfied with the results of the project and stated that they would contact EFS for any future foundation, waterproofing, or concrete stabilization concerns.

Stop Water From Seeping in Finished Basement, Nashua, NH

A homeowner in Nashua, New Hampshire, has lived in their home for a little over a year. Almost every time it rains the homeowner sees water in their basement. They were worried that the water could seep over to the finished side of their basement. They called EFS for a free inspection of their basement so they could find a way to prevent water from seeping over to the finished side of the basement. Our Design Specialist Jason Vachon met with the homeowner and did just that. Jason recommended installing our TripleSafe Sump Pump with 36 feet of WaterGuard/ TrenchDrain and 2 IceGuard with 75 feet of Exterior Drainage Line. 


Our installation team led by Gunther Billhardt began by chipping concrete along the foundation wall where water was entering the basement. Once the concrete was chipped out the team removed enough dirt so we could install our perimeter drainage and sump pump. We connected the drainage to the sump pump basin so water that collects in the perimeter drainage will be guided to the sump pump basin. Next, the team plumbed the sump pump to the home's exterior where we installed 2 IceGuards and 75 feet of buried exterior drainage. The EDL will carry water far from the foundation so water cannot re-enter the perimeter drainage system. After the drainage was installed and buried, we mixed up concrete, covered the WaterGuard, and poured concrete around the sump pump basin to lock everything into place. After the concrete had cured the team showed the homeowner the system. They were very happy with the installation of our perimeter drainage system and no longer have to worry about water seeping into the finished portion of their basement. 

Keep Basement Dry, Nashua, NH

A homeowner in Nashua, New Hampshire purchased their home five years ago, and two years ago, during winter, they noticed water seeping into the basement. They cleaned up the water twice, but they wanted to find a permanent solution to prevent water from entering. The homeowners wanted to convert a section of their basement into a TV room or album collection room, but they couldn't do that if water was still entering the basement. So they contacted EFS for a free inspection of their basement. Our Design Specialist, Bryan Barnard, met with the homeowner and examined the basement to find a solution to prevent water from entering. Bryan recommended installing our TripleSafe Sump Pump, two IceGuards, 30 feet of buried exterior drainage line, and FlexiSpan into the basement to protect the basement from water.

 

Our installation team, led by Gunther Billhardt, started by chipping out concrete to install the basin for the sump pump. The sump pump has a large basin to accommodate our three pumps, so we had to remove 24 inches of dirt. This allowed the pump cover to lay flush with the basement slab. Our team installed the pumps into the basin and then plumbed the pumps to the exterior of the home. Once outside of the home, we installed our two IceGuards and 30 feet of exterior drainage line. After the sump pump and drainage lines were installed and buried, we mixed up concrete and poured it around the basin to lock it into place.

 

Next, the team began installing our FlexiSpan over the crack in the foundation wall. We first covered the crack with the FlexiSpan membrane to prevent water from seeping through the wall and into the basement. We then covered the membrane with a thick adhesive that set hard like concrete. Where the crack meets the floor, our team chipped out a small section of concrete so we could install some drainage. This drain will allow water to flow underneath the home so water cannot enter the basement. After the drain was in place, the team poured concrete around the drain, and the project was complete.

 

The homeowners were very satisfied with the results of the project. They could now make their basement into a TV room or album collection room without worrying about water entering the basement.

Wet Basement Repair, Nashua, NH

A Nashua homeowner recently purchased a house needing major renovations, such as adding a 2nd floor, replacing the roof, and installing a new basement entrance. But during the renovation process, the contractor noticed water seeping through the cold joints in the basement, and recommended a free basement inspection from EFS. The homeowner contacted EFS, and our Design Specialist, Josh Phillips, inspected the basement to find a solution. After the inspection, Josh recommended a waterproofing system that includes perimeter drainage, a sump pump, and a dehumidifier to mitigate the water issue.

 

Our Installation Team, led by Gunther Billhardt, began the process by chipping out the concrete where water was seeping in. We removed any debris and installed WaterGuard, TrenchDrain, and TripleSafe. We placed 42 feet of WaterGuard against the foundation wall to collect any water from the floor or wall. For immovable objects like the heating system and basement door, we used TrenchDrain to go around them. TripleSafe was installed to collect all water from the perimeter drainage. The team installed 2 IceGuard and a 10-foot buried exterior drainage line to ensure that the water was pumped out and away from the foundation. After installing the drainage line, we mixed concrete to cover the perimeter drainage and sump pump inside the basement to lock everything in place. Finally, we installed our SaniDry Sedona Dehumidifier next to the TripleSafe to lower the humidity inside the basement and discharge the moisture into the sump basin.

 

The installed system is highly effective in preventing water from entering and collecting inside the basement, providing a long-lasting solution to the homeowner's problem.

Water Proofing Concerns in Forever Home, Nashua, NH

A homeowner in Nashua, New Hampshire, has lived in this home for over 40 years and plans to spend the rest of their life here. Years ago they noticed water entering the basement and garage. Since the home is a split level these two areas are at the same level. The homeowners wanted to make sure they repaired this so they don't have to deal with water down there in the future. They decided to call EFS for a free inspection and our Design Specialist Josh Phillips met with the homeowners and inspected the basement/garage. He inspected the downstairs of the split level and recommended a solution to collect and remove water from the basement and garage.

Josh's solution was to install 2 TripleSafe, 54' of WaterGuard, 4 IceGuards, 30' of Exterior Drainage, and a SaniDry Sedona Dehumidifier to protect the home from water seepage and moisture in the garage and basement. 

Our installation team, led by Abdou Taal, began by chipping out concrete in the basement and garage to install our drainage and sump pumps. Once that was done, the team installed our perimeter drainage and sump pumps into both the garage and basement. After that, they plumbed both the pumps to the exterior of the home where we installed our IceGuard system to prevent water from backing up in case of a blocked drainage line. Connected to that system is our Exterior Drainage Line which will carry the water away from the foundation of the home. After burying the drainage line out behind the home, the team returned to cover the perimeter drainage and around the sump pumps with concrete to lock them into place. Lastly, we installed the Sanidry Sedona Dehumidifier next to our sump pump in the basement to control the moisture levels.

The homeowners were delighted with the outcome of the project. They no longer have to worry about water coming into their forever home's garage and basement.

Water Entering Basement from Foundation Crack, Nashua, NH

This homeowner in Nashua, New Hampshire, had lived in their home for the past 35 years. A decade ago they noticed a crack forming inside their basement. The crack kept growing every year. After 5 years, the homeowners started to notice water entering the basement from the crack. Now, water leaks into the basement anytime there is rain. The homeowners called EFS for a free inspection of their home to find a solution to their problem. Our Design Specialist Josh Phillips met with the homeowner and had a conversation with them about their concerns. After his conversation with the homeowners, Josh then inspected the basement and recommended installing FlexiSpan over the crack on the foundation wall. 

Our Installation Team led by Steve Dumais installed FlexiSpan over the crack from floor to ceiling to prevent water from entering the basement.

Installing Radon Mitigation System, Nashua, NH

This homeowner in Nashua, New Hampshire, lives in a home that was built in 1973. These homeowners purchased the home in May 2023 and had the home tested for radon during the sale. The results of the test came back over 10 pCi/L, which is high. The way the home is laid out their son's room is in the basement. After living in the home for a couple of months they looked at the harmful effects of long-term exposure to radon gases. The effects shocked the homeowners and they decided to call EFS for another radon test in their home so we could propose the correct solution to lower the radon levels inside the home to below 4.0 pCi/L. Our Design Specialist Josh Phillips met with the homeowners after our radon test came back with results that averaged 11.3 pCi/l. With a number over 10 pCi/L, Josh recommended installing a radon mitigation system that has two extraction points to collect the most amount of radon from beneath the home as possible. 

Our production team led by Branden Edwards, began by creating the two extraction points in the slab of the basement. This will allow us to connect the PVC pipe to the extraction points and guide the PVC to the exterior of the home. On the outside of the home, the team installed our radon fan to the home and then connected the PVC pipe to the fan. After the PVC was secured to the fan the team then used additional PVC pipe to vent the entire system above the roofline of the home. 

After everything was installed the team tested the system and verified that everything was working. The team then met with the homeowner and explained to them that they should let the system run for over a week before re-testing the home.

Upgrading From Temporary Supports to SmartJacks in Basement, Nashua, NH

The original owner of a home in Nashua, New Hampshire, had temporary posts in their basement. The temp posts have been in their basement for years and the homeowner was planning on finishing their basement. They wanted to have the supports looked at before going and finishing the basement. They decided to call EFS and receive a free inspection of their basement. Our Design Specialist Isaac Hernandez met with the homeowner and inspected the basement and the temporary supports. After the conclusion of Isaac's inspection, he recommended replacing the old temporary supports with 6 SmartJacks to support the floors and have them anchored to the slab and the floor system. 

Our Installation Team led by Eric Witham began by chipping out small sections of the basement slab so we could install our big plate footings for our SmartJacks. Once the footings were leveled and installed, the team then measured and cut our galvanized steel supports so they would fit under the beam. After they were cut the team then connected the supports to the footing and installed the adjustable top bracket so they could secure them to the main beam. After everything was installed the team then mixed up concrete and poured it over the footing to lock them into place. 

Concrete Slab Sinking, Nashua, New Hampshire

The town of Nashua, New Hampshire, had reached out to EFS about repairing a utility slab at one of their parks in town. One side of the slab has sunken down a couple of inches and the dirt is now covering two corners of the slab. The town would like EFS to lift the slab using our structural foam. Our Design Specialist John recommended using PolyLevel to lift the slab.

Our Installation Team began by pulling away the dirt that had come over the corners of the concrete slab. The team then used slab jacks to prop up the slab so we could spray PolyLevel beneath. The team sprayed PolyLevel beneath half of the slab and made sure the slab was level before they left.

The town of Nashua was very pleased with the results. 

CleanSpace and Radon Mitigation System Installed, Nashua, NH

A homeowner in Nashua, New Hampshire, had lived in their home since 2007. Recently they have become worried about the radon levels in their home. When they tested their home for radon the test results came back at an average of 9 pCi/L. The recommended amount for radon is for it to be below 4.0 pCi/L so the homeowner decided to call EFS for a free inspection. Our Design Specialist Josh inspected the home and asked the homeowner some questions about their home. One question Josh asked is if they had a crawlspace and if they have any concerns with it. The homeowner did have a crawlspace and a basement but they say the crawlspace smells. Josh recommended installing a Radon Mitigation System to lower the radon levels but also installing CleanSpace to encapsulate the crawlspace and get rid of the smell. 

Our installation team began by installing the Radon System. They first made an extraction point in the slab in the basement and fed PVC pipe to the exterior of the home where they installed the radon fan to the side of the home. Once the PVC pipe and the radon fan were connected the team then used more PVC pipe to vent the system above the roofline of the home. Next, the team began installing CleanSpace into the crawlspace. The team laid 811 sqft of CleanSpace on the floors and walls of the crawlspace to protect the crawlspace from moisture coming up from the ground. The moisture was causing the crawlspace to smell and this crawlspace encapsulation will prevent any moisture from penetrating the crawlspace. 

The homeowner was very pleased with the results of the project. They initially called just for radon concerns but ended up getting a solution for a problem that they didn't know was easy to solve. 

High Radon Levels in Home, Nashua, NH

A homeowner in Nashua, New Hampshire, has lived in their home since 2017, and ever since they purchased the home they were concerned with the radon levels in the home. A couple of years ago the homeowners had their home tested for radon and the levels were higher than the recommended amount. They didn't do anything at that time but recently they decided to test the home again and the levels have increased from the last test. The homeowners decided it was time to solve this issue and they reached out to EFS for a free radon appointment. Our Design Specialist James visited the homeowners and designed a radon mitigation system in their home.

Our installation team installed a radon mitigation system in the home to lower the radon levels. The system was able to lower the levels from around 10.6 pCi/L to a comfortable level under 4.0 pCi/L. 

Foundation Settlement Causing Cracks, Nashua, NH

A homeowner in Nashua, New Hampshire, had lived in their home for the past 30 years recently they've noticed some cracking in their foundation. The homeowner would like to have someone look at the cracks because the water has begun to enter the basement through the cracks. They reached out to EFS for a free inspection of their foundation and the water entering their basement. Our Design Specialist John recommended installing 4 Push Piers to the settling portion of the foundation. 

Our team followed John's plan for installing the Push Piers into the basement. Where the foundation of the home meets the foundation of the garage was where the most settlement had occurred. The team first marked where each of the Push Piers will be installed. Then they chipped out a small section of concrete and then removed dirt until they reached the footing of the foundation wall. Once to the footing the team chipped out a section of the footing and installed our Push Pier brackets, the team then began pushing piers down into the soil below until we hit sufficient pressure to stabilize the home. After all the Piers were installed and under sufficient pressure, the team then capped all of the piers and backfilled them with dirt, and repoured concrete over the dirt to match the basement floor. After the Piers were finished the team sealed the small cracks in the foundation with NexusPro. 

The homeowners were happy with the results of the project. They no longer have to worry about the foundation settling and or water entering the basement from the cracks. 

Cracks in Cinderblock Foundation, Nashua, NH

A homeowner in Nashua, New Hampshire, has lived in their 70-year-old home for the past five years. Over the past 5 months, they noticed cracks in their Cinderblock foundation wall. They have become increasingly concerned with the structural integrity of the home and have done a lot of work already and don't want it to be compromised. The homeowners called EFS for a free inspection of their home and our Design Specialist John examined the basement and created a solution for the home. John recommended installing 7 Geolocks to the foundation of the home. 

Our production team began settling up for installing our Geolock Anchors on the cinderblock foundation wall in the basement and on the outside of the home. The team first created a trench in the yard on the side of the home to install one side of our Geolock Anchors. After the trench was dug out, the team then marked the foundation wall where each Geolock will be installed. After marking where each SJ will be installed the team drilled holes through the foundation wall and then fed a galvanized rod into the trench into the yard. Once the rods were all sent into the trench the team put a Geolock Plate on the ends of the rods and used impact guns to tighten the Geolocks until they began taking pressure off of the wall. The team tightened all of the Geolocks and then backfilled the trench in the yard. 

The homeowner was relieved after our team installed the 7 Geolocks to their Cinderblock foundation to stabilize it. 

Radon Mitigation System, Nashua, NH

A homeowner in Nashua, New Hampshire, had recently moved into this home. They had the home tested for radon during the purchasing process. The results of the radon test came back at 20.7 pCi/L. The new homeowners decided to call EFS for a free radon inspection. Our Design Specialist James inspected the home and designed a radon mitigation system for the home. 

Our production team spent a couple of hours installing the extraction point, PVC, and radon fan into the home. After installing the system, the team tested to ensure the fan was working and that air was traveling through the PVC system. 

The homeowners were pleased with the outcome of the project. They no longer have to worry about high levels of radon in their home anymore. 

Leaking Foundation was Causing Concern, Nashua, NH

A homeowner in Nashua, New Hampshire, had moved into their new home 5 weeks ago. Since the purchase of their home, they've had an inspection that revealed a foundation crack that was allowing water into their home. The homeowner had become increasingly concerned with the crack and decided they wanted to find a permanent solution before the problem got worse. They decided to call EFS for a free inspection, and our Design Specialist Victor recommended installing a full perimeter drainage system to protect the home from water entering the home. Our perimeter drainage system includes WaterGuard, CleanSpace, UltraSump, and an IceGuard to protect the home from water entering the basement. 

Our production team first began by chipping out a strip of concrete around the entire perimeter of the basement. When chipping around the basement the team had to avoid two obstructions; the water heater and the radon extraction point. Once the team chipped out the perimeter of the basement they laid 140ft of WaterGuard and installed an UltraSump that was integrated into the WaterGuard system. After the WaterGuard and UltraSump were installed the team then mixed and poured over the perimeter drainage and around the sump basin to eliminate any tripping hazards. Next, the team installed and encapsulated all of the walls in the basement with CleanSpace and directed the encapsulation into the WaterGuard. After the team installed the CleanSpace our team then continued to plumb the UltraSump to the exterior of the home where we installed an IceGuard. The IceGuard will prevent water from backing up into the basement. The team installed the drainage line after the IceGuard and extended it at least 10ft away from the home. 

The homeowners were very pleased with the results of the project. 

Cracks in Foundation Making Home Difficult to Sell, Nashua, NH

A homeowner in Nashua, New Hampshire was in the process of selling their home. The home had been on the market for a while and they found that some cracks in their foundation has resulted in a sticking point for the sale of the home. After a few potential buyers stressed concern with the cracks in the back of the attached garage, the homeowner decided they needed to have the cracks on the foundation repaired. The homeowners decided to call EFS for a free inspection, and our design specialist found that the root cause of the cracks was that the walls were bowing.

Our design specialist recommended installing Geolock wall anchors and Crack Injection to the foundation wall. 

Our production team began by prepping to install the Geolocks to the foundation wall. The first step was to create a trench inside the garage to mount one side of our Geolocks to. The team used a jackhammer to create a trench nearly the width of the garage which was long enough to hold 4 Geolocks inside. The team removed the concrete and dug down a couple of feet to ensure that the Geolock Plates will fit in the trench. Once the trench was set up the team then drilled small holes in the outside foundation behind the garage. Using those small holes the team sent a rod from the exterior of the home into the trench inside the garage. Once all 4 rods were sent into the garage the team attached Geolock Plates to either side of the rod and used an impact gun to tighten the rods. The rods were tightened until the wall was stabilized. After the wall was stabilized, the team then proceeded to use crack injection to seal the cracks in the foundation wall.

The homeowner was very happy with the results of the project. They were now confident that their home will sell for their asking price. 

Water Seepage in Basement, Nashua, NH

A recent buyer of a home in Nashua, New Hampshire, had noticed water entering their basement and collecting on the floor. They have only lived in the home for a week and want the issue fixed immediately. They decided to call EFS for a free inspection, and our design specialist recommended installing a TripleSafe, IceGuard, WaterGuard, and a SaniDry into the basement to mitigate the water entering the basement. 

Our production team first began by chipping out concrete along the foundation wall so they could fit the WaterGuard and TripleSafe against the wall. The team chipped out 120' of concrete along the wall to fit the WaterGuard and sump pump. Once the concrete and debris from the wall were removed the team began to place the WaterGuard into the trench. After the WaterGuard was laid into the trench, the team then installed the TripleSafe and connected it to the WaterGuard.

Condos Walkway Needs Repair, Nashua, NH

A condo in Nashua, New Hampshire, had some walkways that were sunken and cracked. Residents of the condo have noticed the cracking and sinking, and the association wanted to have the walkways repaired before someone could get hurt. The condo association decided to call EFS for an inspection, and our design specialist recommended installing PolyLevel and NexusPro to lift, level, and seal the cracks on the walkway. 

First, our team will lift and level the concrete. To allow the PolyLevel to be effective the team must drill small portholes through the concrete walkway. The portholes will allow the team to inject PolyLevel underneath the walkway to slowly and precisely lift it. If a slab needs to be lifted more than an inch or two our team would try to use slab jacks to aid in lifting the slab. The slab jack will temporarily lift the slab to make a void underneath, the team will then spray PolyLevel into the void to lift the slab. Once the slabs were level the team then used NexusPro to seal any cracks on the walkway. A caulking gun was used to lay a bead of NexusPro across any cracks in the slab. The team then used caulking spoons to push and spread the NexusPro deep into the cracks to fully seal them. Once all of the cracks were sealed and the slabs were lifted and leveled the job was complete. 

The condo's tenants and association were happy with the work that Erickson Foundation Solutions provided.

Water Was Coming Through Cinder Block Foundation, Nashua, NH

A homeowner in Nashua, New Hampshire, has lived in their home since the late '90s. In the past 2 months, they have noticed water entering their basement from the cinder block foundation. The homeowner planned to sell their home in 2025, so they wanted to make sure the value of the home was as much as it could be by then. The homeowner planned on making repairs until they decided to sell the home. They decided to call EFS for a free inspection of their basement. Our design specialist examined the basement for possible leaks in the foundation. During their inspection, the specialist found a couple of areas where water was entering through the foundation, but they also found that their front-facing foundation wall was bowing inward. Our design specialist recommended a perimeter drainage system with CleanSpace into their basement and installing PowerBraces on the front-facing foundation wall.

Our production team began by ensuring that everything was removed from the perimeter of the basement so they could access the walls and floors. The team then chipped out concrete at the base of the foundation walls for us to install the WaterGuard at the foot of the wall. After the concrete was chipped out, the team started installing the CleanSpace across the foundation walls. Once all of the CleanSpace was installed, the team moved on to set up the PowerBraces. The team installed 7 PowerBraces on the front-facing foundation wall. After the PowerBraces were installed, the team installed the WaterGuard around the perimeter of the basement. To install the water drainage system where the PowerBraces were installed, the team had to use piping that would allow water to flow around the L Bracket at the bottom of the PowerBraces. Once the perimeter drainage was completed the team mixed up concrete and poured it over the perimeter drainage system. 

The homeowner was very happy with the results of the project. They no longer have to worry about water coming into their basement and they can focus on making upgrades to their home before they sell it in 2025.

Mouth of Garage Has Become Eye Sore, Nashua, NH

A homeowner in Nashua, New Hampshire, purchased their forever home 2 years ago. The home was built in 2000 and at purchase, they noticed that something was wrong with the apron of the garage. Over the first two winters since purchasing the home, the mouth of the garage has gotten worse. The homeowner would like to have the apron repaired because it is an eyesore. Our design specialist Kenny recommended chipping out the apron of the garage and pouring a new apron. 

Our team first started by chipping out the apron of the garage using jackhammers. The team chipped out 8-12" of concrete so they can replace the apron of the garage. After the concrete is removed the team began mixing concrete. The team made framing so they can make a form for the apron. The team poured and smoothed the concrete inside of the form and then waited for the concrete to cure. Once the concrete is cured the team removed the form. 

The homeowners were happy with how their new garage apron looked.

Cracking Garage Slab, Nashua, NH

A homeowner in Nashua, New Hampshire, had lived in their home for 45 years, and about 10-15 years ago they noticed cracking and shifting in their concrete.

The homeowner wanted to repair the cracks in the garage because it had started affecting the mudroom inside their house and could potentially affect a sale in the future. The homeowner planned on moving to Florida sometime shortly. Our design specialist recommended installing PolyLevel and NexusPro to fill the void, lift, level, and seal cracks on the garage slab.

Our PolyLevel Crew repaired the garage by injecting PolyLevel under the slab. The team used our Polyrig to fill the void underneath the slab. Once the void was filled the team performed a lift and level procedure to areas that had sunk.

Foundation Wall Bowing, Nashua, NH

Paul G. recently purchased this home in Nashua, NH and had some immediate foundation concerns to address. During the home inspection process, there was a clearly visible, horizontal crack in the foundation wall in the basement. The concrete wall was about 6 and a half feet tall, and bowing in due to pressures from the soils on the exterior. Eventually this foundation wall would completely push in and fail. He planned on living in the home with his family for many years, so Paul needed a permanent solution.

Design specialist Jason Vachon completed a thorough inspection of the bowing wall for Paul, and proposed the installation of PowerBraces as a solution. The PowerBrace system is quick and efficient, requiring no excavation or heavy demolition of concrete in order to install.

Project foreman Nate Erickson and installation specialist Anthony Correa were able to complete installation of the designed PowerBrace system in a single day, and Paul's foundation wall is now permanently stabilized. Overtime, the wall may possibly be straightened as well, though the fix for now was to prevent any further bowing movement and improve the integrity of the concrete wall.
