Concord, NH Foundation Repair, Radon Mitigation and Testing Services

Mark F. is a homeowner in Concord, New Hampshire who plans on traveling in the near future. Although he already has a sump pump, leaks in the basement occur almost every time it rains. Constantly cleaning up the mess, storage getting damaged, and concern that flooding will get worse were all reasons why Mark reached out to us to make sure his basement stays dry.

After our Design Specialist completed a free home inspection, he recommended adding perimeter drainage to capture all the excess water that the sump pump alone couldn't. This eliminates heavily water-saturated soil putting pressure on foundation walls, causing them to leak. Installing out WaterGuard perimeter drainage system was a smooth process, as our team was able to complete the job in one day. Within that time, our installation crew chipped out space to lay the WaterGuard system, put the system in place along with crushed stone, connected it to the existing sump pump, and then cemented WaterGuard in place.

Adding perimeter drainage to the sump pump goes a long way. With this waterproofing system in place, Mark can enjoy traveling while knowing that his basement will stay safe and dry.

A homeowner in Concord, New Hampshire, purchased a home built in the late 1800s in August 2022. In order to appeal more to the seller, they waived the inspection, which resulted in some unknowns leading to the future of owning their home. During heavy rainstorms, water and small critters entered their basement, and they reached out to EFS for a free inspection. Our Design Specialist, Jason Vachon, met with the homeowner and inspected the basement. Jason found some voids in the foundation wall that could be sealed with our PolyLevel Wall Restoration. During his inspection, he also found that the basement had high humidity and that the temporary supports needed to be replaced. Therefore, Jason recommended installing a SaniDry Sedona Dehumidifier and Lally columns to be installed in the basement as well.

Our installation team began by installing our PolyLevel Wall Restoration. Since the team was spraying a foam, the homeowners had to remain out of the home for a period of 24 hours. This was just a precaution for the homeowners. After the Poly was sprayed, our team left and then returned at a later date to install the Lally columns and SaniDry Sedona Dehumidifier. To install the Lallys, the team first chipped out three small sections of concrete and poured footings for them to rest on. After the footings were cured, the team installed the Lally columns and then poured more concrete around them to lock them into place. Lastly, the team installed our dehumidifier in the basement to control the humidity.

The homeowners were very pleased with the results of the project, as they no longer have to worry about water or critters entering their basement.

The owner of a house in Concord, New Hampshire has been living in the same place for 35 years. Recently, they started using their basement as a workout space but noticed that it was very damp and this worried them. They contacted EFS to schedule a free inspection. EFS sent their Design Specialist, John Prince, to meet with the homeowner and discuss their concerns. After their conversation, John inspected the basement to find a solution to the issue. He went over the whole basement and then created a proposal for the homeowner. EFS proposed installing a full perimeter drainage system, which would include a TripleSafe sump pump and a SaniDry Sedona dehumidifier. This solution would eliminate any water issues in the basement and also control the humidity to prevent dampness when the homeowner works out in the basement. 

The EFS Installation Team, led by Anthony LoCascio, began by chipping out concrete around the perimeter of the basement. They then used jackhammers to break up the concrete into small pieces to create a trench for installing 102 feet of perimeter drainage and the sump pump at or beneath slab level. In addition to the normal WaterGuard perimeter drainage, they also installed 8 feet of Trench Drain WaterGuard around the oil tank. After all of the drainage and the sump pump were installed, the team plumbed the TripleSafe sump pump to the exterior of the home. While the pump was being plumbed, the other members of the team began mixing concrete to install around the sump pump and Trench Drain, then covering the rest of the WaterGuard with concrete. While the concrete was curing, the team moved outside to install 2 IceGuard and the buried exterior drainage line to carry water away from the foundation. The last item installed was the SaniDry Sedona dehumidifier, which was placed next to the sump pump. The team ensured the dehumidifier had power and fed the discharge line into the sump pump. With the perimeter drainage system fully installed, the homeowner can now work out in the basement without worrying about a damp space. They can be confident that there will be no water or unwanted dampness in the basement.

This homeowner in Concord, New Hampshire has lived in an early 1900s home since September 2021. After they purchased the home they noticed that a section in their rock and brick foundation was bowing outward. They had become worried about the stability of the foundation wall and decided to call a knowledgeable foundation company about their concerns. They scheduled an appointment with EFS and our Design Specialist Jason Vachon met with the homeowners and recommended a solution to stabilize the foundaiton wall. He recommended installing an Auxiliary Wall against the foundation wall to add stability to the foundation wall. 

Our installation team led by Nick Carelli and his team installed an 8-foot Auxiliary wall on the foundation wall. To install the Aux wall we had to first pour a footing that would support the new wall. Once cured we then installed PowerBraces, rebar, and our concrete forms. After that, we scheduled a concrete delivery to fill the forms up to the top and then waited for the concrete to cure. After fully cured we then removed the concrete forms and trimmed off any imperfections from the concrete.

The homeowner was very impressed with the Auxiliary wall that our team installed. 

A homeowner in Concord, New Hampshire, purchased their home in 2016 and has been upgrading and repairing items around the home. The home was built in the early 1900s and the homeowners wanted to make sure the supports in the basement were strong enough to support the modern-day appliances. The homeowners called EFS for a free inspection of their basement by our Design Specialist. Our specialist Jason Vachon met with the homeowner and talked to them about their concerns. After their talk, Jason went into the basement and inspected the floor system. After his inspection, he recommended installing 3 SmartJacks and a 16-foot supplemental beam to add support to the floor system. 

Our installation team led by Eric Witham began by chipping out small sections of concrete so we could install our big plate footings. After the concrete was chipped and the debris was removed we then poured crushed stone into the hole where the footings will be installed. Next, we installed the big plates and then measured and cut each SmartJack to the correct size. We then installed each SmartJack and the supplemental beam beneath the floor system. After the system was installed and everything was leveled we then mixed up concrete and poured it over SmartJacks footings to lock them into place. 

The homeowner was very pleased to cross another item off their list. They can already feel the difference in the floors. 

The owners of this home in Concord, NH had lived there for about a year and knew there were some concerns they needed to address. At the back of the house on the exterior, there was a large concrete patio extending from the edge of the home's foundation all the way to the pool deck. The concern with this concrete slab was it sloped towards the home instead of being level, or sloping away from the home. This meant when it rained, all the run off drained towards the house, and ultimately was leading to the homeowners having a wet basement full of unwanted moisture. After addressing the moisture concern on the interior of their basement, they knew the situation on the outside of the home also needed to be fixed.

Our specialist, Victor Tapia, designed and proposed the ideal solution with our PolyLevel injection. Through slab jacking the sloping patio, the homeowners would not need to consider demolishing or removing any concrete, which would have been a noisy and messy process. Instead, the polymer foam injection process is quick, clean, and efficient. 

Led by Nick Melo, our concrete repair specialists were able to complete the project in a single day, lifting and repairing the entire concrete slab to the desired height and slope. Ensuring the water run-off would now flow away from the home instead of towards it, the then sealed the perimeter of the concrete where it abutted the foundation, adding a further layer of protection. 

The homeowners were pleased with the work and had incredible peace of mind that their basement was going to stay dry, and that their slab was in good condition. 

The town of Boscawen, New Hampshire, reached out to EFS because they have seen more and more water entering their garage since they started using it. They have police cars that stay in that garage and might have water/ snow running off of them. The runoff is then collected on the back wall of the garage. The town of Boscawen reached out to EFS for an inspection of the garage. Our Design Specialist Josh inspected the garage and recommended a drainage system that will collect the water that has run off the police vehicles. 

Our installation team began by chipping out concrete in front of a shelving unit that was installed on the back wall of the garage. The team chipped across the entire width of the garage. In this trench, the team installed our SuperSump on the right side of the trench and then installed TrenchDrain WaterGuard to the remaining 39' across the garage. After the team set up the sump pump and the drainage into the concrete trench, we then mixed concrete next to the TrenchDrain and around the SuperSump basin to lock them into place. 

The Boscawen Police Department was very happy with the results of the project. They no longer have to worry about water collecting in their garage. 

The owner of this family heirloom home in Concord, New Hampshire, had lived in their home since they were born. The home was built in the 1860s. Since the owner could remember they have noticed sticking doors and windows in the home. The owner doesn't live in the home anymore by uses it as a rental home and would like to preserve the estate for generations to come. To ensure that the home will be preserved,  the homeowners decided to call EFS for a free inspection of their foundation. Our Design Specialist Liam visited the home and inspected the entire foundation and looked for potentially concerning issues that could affect the foundation or internal structure of the home. After Liam's inspection, he recommended rebuilding 2 sections of the home's foundation wall with a new masonry block wall, installing 4 EZ post supports under the front porch roof, and installing 26 SmartJacks with 112' of Supplemental Beam to support the floor system of the home. 

Our Installation team will first install the SmartJacks and Supplemental Beams into the basement to strengthen the floor system of the home. To begin setting up for the SmartJacks the team first had to create footings for the SmartJacks. The floors in the basement were half concrete and half dirt so the team had to use two different methods of installing the footing of the SmartJacks. The two processes were similar but slightly different. On the dirt floor, the team would create a hole that would fit our big plate footing. Next, the team would install rebar, engineered fill, and then concrete to create a strong footing. Once the concrete was cured the team installed our big plate over the concrete and installed the SmartJack to the floor system of the home. For installing the footing on the concrete slab portion of the basement the only differences were chipping out a section of concrete before digging out where we would install the big plate, and then after the plate was installed the team would pour concrete over the footing to lock it in place. After all of the SmartJacks were installed and the supplemental beams were in place the team used the adjustable top bracket of the support to lift and add stability to the floor system of the home. 

After the SJs were installed, the team moved on to prepping the 2 sections of the foundation walls to be rebuilt with Masonry Block. The first step was to remove dirt from against the foundation wall to the footing so the team could set up temporary supports and remove the foundation wall. After the section of the wall was removed, the team poured a new concrete footing and waited for it to cure. Once it was cured our Lead Mason Nick would lay his starter blocks and then start building up the wall to the rim joist. Once the wall was built to the rim joist the team installed Sentry Seal to cover the outside wall of the foundation to guard against water seepage. After the Sentry Seal was installed the team then removed the temporary support and backfilled the dirt against the foundation wall. 

The homeowner was very impressed with EFS. The installation of everything went smoothly and the home is now structurally sound. 

This homeowner in Concord, New Hampshire, has lived in their home for about 20 years. A couple of years into owning the home the homeowner started to notice some sagging of the floors around their home. The problem hasn't gotten worse in around 18 years but the homeowner would still like the problem looked at. They decided to call EFS for a free inspection and our Design Specialist Victor examined the floor system and recommended installing 3 SmartJacks with a 9' Supplemental beam to add support to the floor system. 

Our installation team began by chipping out 3 footings for the SmartJacks. The team installed our big plates underneath the slab and then installed the rest of the SmartJacks and the supplemental beam against the floor system. The team used the adjustable top bracket of the SmartJacks to lift the floor system and level the floor as much as we could. After all the lifting was complete the team mixed up concrete and covered the SmartJack footings with concrete to lock them in place. 

The homeowner was very happy with the results of the SmartJack installation in their basement. 

A homeowner in Concord, New Hampshire, has lived in their over 100-year-old home for the last 40+ years. They don't know exactly when it started but a long time ago they noticed a sag on the main floor of the home. They finally decided they would like to have this corrected so they reached out to EFS for a free inspection of their home. Our Design Specialist Victor recommended installing 6 SmartJacks with a 28' Supplemental beam and a SaniDry into the basement to eliminate the sag in the floors and reduce the moisture in the basement. 

Our installation team began by marking where to install each SmartJack in the basement. The team will install 3 SmartJacks and 14' of Supplemental beam to the section of the basement near the stairs into the basement, the other 3 SmartJacks and 14' of Supplemental beam will be installed on the side of the basement near the washer and dryer. After all the locations of the supports were marked, the team began chipping out concrete to install our big SmarkJack footings. Once the team installed all 6 footings they then started installing the supplemental beams and SmartJacks. To attach the supports and the beam the team propped up the beam using a series of ties to hold the beam up while they secured the SmartJacks to the beam with our U bracket. The team secured all the supports to the two beams and began to lift up the floor system using our adjustable bracket on the SmarkJacks. After the floor was lifted and leveled, the team then poured concrete over the footings of the SmartJacks. Lastly, the team installed a SaniDry in the basement to manage the humidity in the basement. 

The homeowners were very pleased with the work done by EFS and the homeowners no longer have to deal with sagging floors on their main floors. 

The owner of a family heirloom in Concord, New Hampshire, had lived in that home since they were a child. During their childhood, over 40 years ago, the now homeowner noticed the floors weren't level and were sloping. Flash forward 40+ years and the floors were still sloping and out of level. The homeowner plans to keep the heirloom in good condition so it can be used for future generations. The homeowner decided to call EFS for an inspection of the floor system in their 1860s home. Our Design Specialist Liam recommended installing 10 SmartJacks, 16 SmartJacks XT, and 112' of Supplemental beams into the basement to support the floor system in the main living area of the home. 

Our production team started by marking where each of the 26 new supports will be installed. Once all of the locations for the new supports were marked the team began removing dirt from the dirt floor basement so they could pour concrete bases for the regular SmartJacks to rest on.  Once the concrete was cured the team installed the regular SmartJacks over the concrete and attached our adjustable bracket to the supplemental beam to support the floor system above. For the SmartJack XTs, the team just removed some dirt and poured some engineered fill into the hole, and installed our big plate footings over it. The team then installed the support to the big plates and then to the beam above. The XTs were installed in the main area of the basement and supplemental beams were alternated with every other load-bearing beam. Once all of the supports were installed the team used the adjustable brackets to lift and level the floors back to their original place. Once everything was pressurized the team covered the support with concrete to lock them in place. 

The homeowner was very happy with the results of the project. 

A homeowner in Webster, New Hampshire recently inherited their father's home. Their father had lived in the home for 50 years and they noticed one of the foundation walls in the basement had cracks and seemed to be leaning inward. The homeowner decided to call EFS for a free inspection of their foundation wall. Our design specialist recommended installing PowerBraces to the interior foundation wall to add support to the bowing wall. 

Our production team began by measuring out where each of the 3 PowerBraces will be placed against the wall. Our team evenly spread out each PowerBrace to then installed an L bracket where the floor meets the wall. After the team installed the L brackets they then began to install the upper brackets of the PowerBrace. Depending which way the floor joists were traveling will determine which floor joist bracket our team will use. Once the correct bracket was installed in the joists the team then installed the PowerBrace itself to the bowing foundation wall. Once the PowerBrace was mounted against the wall, the team then used the top bracket to tighten and create a force against the wall to prevent the wall from further bowing. 

The homeowner was happy with the results of the project. They no longer have to worry about that bowing foundation wall. 

A homeowner in Concord, New Hampshire, had purchased their home a year ago and then noticed a crack in the foundation wall in the basement. After they purchased the home the homeowners forgot about the crack until one rain storm flooded their basement. After they cleaned up their basement the homeowner decided they needed to have the crack in their foundation repaired. Our design specialist recommended installing a Crack Injection, NexusPro, and a SaniDry into the basement to prevent water from entering the basement. 

Our production team began by installing Crack Injection to the crack on the foundation wall. They used injection foam and a sealant to seal the crack in the basement. After the foundation crack was sealed the team sealed any other small cracks with NexusPro. After all of the other cracks were sealed the team installed a SaniDry dehumidifier in the basement to control the humidity in the basement. 

The homeowner was happy that they no longer have to worry about water entering their basement anymore. 

A homeowner in Concord, New Hampshire, had concerns with water coming into their basement. They have lived in their home for 52 years and in the last 3 years have noticed water coming into their basement. They decided to call EFS for a free inspection and our design specialist recommended installing an UltraSump, WaterGuard, and IceGuard to stop water from collecting in the basement. 

Our production team began by chipping concrete in the basement where the water was entering. The team chipped out a basin for the sump pump and a space for the WaterGuard to be installed. After the team chipped out the concrete, the team began removing dirt for the sump pump basin. After the basin was dug, the team set the UltraSump in the basin and plumbed the drainage outside. The team continued and installed the 8 feet of WaterGuard to the left of the UltraSump. After all of the WaterGuard was installed the team started to lay concrete over the WaterGuard and around the UltraSump. While the concrete was curing the team installed an IceGuard over the drainage line outside the home to protect the drainage line from backing up water back into the basement. Once the concrete cured the job was complete. 

The homeowner was happy that Erickson was able to stop the water from collecting in their basement. 

A homeowner in Concord, New Hampshire, was experiencing some settlement in their home. The back of their home had a significant slope. The residence had a wooden retaining wall that held dirt up for a walkway behind the home. Our design specialist Nate assessed the home inside in out. Nate found 2" of settlement toward the back of the home. In addition to the home settling, Nate worried about an elevated deck on the back of the home is in danger of settling as well. Nate recommended installing a bigger concrete retaining wall that will hold the soil better than the wooden one. Nate planned to add Helical anchors and EZ posts to help secure the supports of the deck. 

Our production team led by Nick C. began the project by removing the old retaining wall and several feet of dirt so they could pour a footing for the new retaining wall. Once the dirt was removed, the team created a form to pour concrete into. The team poured the footing and let it cure. Following the footing being cured, the team set up additional forms to create the retaining wall. The team called in a concrete truck to fill the forms with concrete. The team had set up holes in the wall to allow for the helical anchors to attach to the EZ posts. After the retaining wall is cured, the team attached the Helical anchors to the EZ post. 

The team was able to secure the home's foundation and prevent further settlement of the home and porch. 

A homeowner in Concord, New Hampshire, had concerns about the floors of their home sloping in their 100-year-old home. Over the past couple of years, the sloping of the floors had gotten worse each year. The homeowner would like to take care of this issue now. Our design specialist examined the floors of the home. They found significant sagging on the main floor of the home. In some areas, the floor had sloped up to 3". 

Our production team installed 7 SmartJacks into the basement of the home. The team first chipped out the concrete under where each SmartJack are going to be placed. The team used a jackhammer to break up the slab so that they can pour a new footing for the SmartJacks. The team chips out a 24" x 24" x 18" hole to install rebar and concrete to create a base for the SmartJack to rest on. After the base or footing is cured, the team set the SmartJack on top of the footing and secured it to the beam above. After all the SmartJacks are secured to the beam, the team then has to wait for an inspector to verify that the SmartJacks are installed to the building department's standards. Once the inspector verified that the SmartJack are installed to code, the team poured concrete over the SmartJack footing to secure them in place. 

A homeowner that lived in their forever home in Concord, New Hampshire, was experiencing settlement in their foundation. The back of their property had a severe slope pitching away from the house.  Our design specialist examined the property and inside the house and discovered that the slope at the back of the home had caused the settlement, as the soil around the home gradually slid away.

The EFS production crew installed Push Piers at the back of the home to address this settlement concern. The Push Piers effectively went down into the ground beneath the foundation walls until they reached depths with stable soils. The piers were then able to slightly lift and permanently stabilize the home. The homeowner was relieved that their forever home was repaired and warrantied for 25 years against any further settlement. 

This homeowner in Concord, New Hampshire was experiencing some settlement in the foundation of their home. This homeowner had just purchased this home as an income property and would like to repair the home so that tenants can move in. She decided to call EFS for a free inspection.

Design Specialist Michael LaMalfa inspected the home. Michael found that there are signs of settlement in the foundation. Michael recommended installing SmartJacks.

Crew Lead Spencer Ladd and his team arrived and installed the SmartJacks in the basement. 

The homeowner was very happy with the results of the project. 

This homeowner in Concord, New Hampshire was experiencing some cracking and sinking in the back of their home. They decided to call EFS for a free inspection.

Design Specialist Michael LaMalfa arrived at the home and inspected the homeowner's concerns. Michael confirmed that the back of the home was settling down the hill in the backyard. Michael recommended installing some Push Piers to attach to the foundation and some Ez Post to install to the deck posts. 

Crew Lead Ed Nadreau and his team arrived at the home and began installing the Push Piers and EZ post to the back of the home. 

This homeowner in Concord, New Hampshire was experiencing water entering their basement. They decided to call EFS for a free inspection. 

Design Specialist Jason Vachon arrived at the home and inspected the basement. Jason Vachon recommended that the homeowner have 113' of Water Guard installed in their basement.

Crew Lead Branden Edwards and his team arrived at the home and installed Water Guard into the basement.

Robert R. of Concord, New Hampshire has been experiencing cracking and unlevel floors in his garage. The floors are causing a tripping hazard. In fact, Robert's wife has tripped several times. Robert called Erickson Foundation Solutions to see if someone could come and suggest a repair solution. 

Design Specialist Paul Magowan came to the home and inspected the garage. He found that all the crack was in the first 4 feet of the garage door. He recommended cutting out that 4-foot section of the garage slab and pouring a new one. Robert requested if Erickson could find a way to make the water from the gutters travel through an underground drainage system. 

Crew Lead Nick Melo and his team came to Robert's home. Nick cut out the section of the garage that had the cracks in it. After, they brought in some dirt and made the area level. Then they poured the new slab and made sure it was level. 

While the new concrete slab was drying a second team led by Spencer Ladd came to the home to rework the gutter system. The team connected a pipe to the gutters and dug a trench for the new pipe. The trench was dug away from the home to ensure water wouldn't go under the foundation. 

Homeowner Dale had lived in his home for over 24 years, though the home itself was built in 1976. The original homeowner had installed a drain of some kind in the floor of the garage slab, and so over 50 years water was flowing into this drain and seemingly straight into the soil beneath it. When Dale purchased the home, he noticed the drain and the fact that the slab had shifted a bit. However, it wasn't a must fix for him at the time. In recent years, the slab had begun to crack and shift more and more, and Dale knew it was time to address the issue before things got worse. In some places near cracks, there was settlement of up to 3/4 of an inch. Replacing an entire garage slab could be costly, and so he sought out other options. His ultimate goal afterwards was to also have the surface painted to brighten up the garage space.

Design specialist Paul Magowan met with Dale and inspected the garage slab. Paul concluded PolyLevel would be an appropriate solution for the problem, and proposed the fix and costs involved. Dale was thrilled to learn he would not need to replace the slab entirely, and hired Erickson Foundation Solutions to install the PolyLevel to fill the voids beneath the slab, and lift and stabilize his garage floor. 

Crew lead Nick Melo and his team were able to lift and stabilize the concrete garage slab, as well as seal on the cracks with NexusPro, all in a single day. Dale was able to use and even drive his vehicle back into the garage space within 30 minutes of job completion. The PolyLevel solution saved Dale time and money, and now he can repaint the garage floor and have peace of mind that it is stabilized and will likely no longer shift or crack.

Evan P. of Concord, New Hampshire was curious about radon levels in his home. He called Erickson Foundation Solutions to see if we could set up an appointment to come out to his home. The home was tested with a CRM machine by Design Specialist Paul Magowan. The results of the test came back at 3.8 pCi/L.

Crew Lead Branden Edwards and his team came to the home and installed a radon system.

Evan was impressed by how quick and easy each step of the process was.
