Manchester, NH Foundation Repair & Radon Mitigation Specialists

A homeowner in Manchester, New Hampshire, had a retaining wall on the side of the home that held two Air Conditioning units on the top. The retaining wall had cracked and the homeowner was becoming concerned and didn't want the problem to worsen and potentially injure someone. The homeowners decided to call EFS for a free retaining wall inspection. Our Design Specialist Jason recommended installing Geolock Anchors to stabilize the retaining wall.

Our production team will install 3 Geolock Wall Anchors to the retaining wall. We used a coring drill to make a hole in the retaining wall to drive our galvanized rod through the concrete. Our team used an impact driver to push the galvanized rod approximately 10' into the dirt that the retaining wall was holding up.  Our team then used our Geolocks on both sides of the rod to use the soil between the plates to support the retaining wall. 

The homeowners were delighted with the installation of the Helical Anchors and now don't have to worry about the retaining wall injuring someone.

Our Design Specialist Jason inspected the commercial building and recommended sealing the crack in the foundation by using FlexiSpan and then recommended installing WaterGuard around the perimeter of the basement to collect any additional water that enters the basement. 

Our team installed 232' of WaterGuard around the perimeter of the basement and sealed the crack in the foundation with FlexiSpan. 

Our system will collect any water that comes into the basement and expel it through the WaterGuard system around the perimeter of the basement. 

The owner of the commercial building was pleased that their issue was resolved quickly by the EFS team.

In the last couple of months, the homeowner's have noticed cracking and settlement in their house causing cabinets out of level and tight door jams. The homeowner wanted to be able to sell their home in the future with a "good conscience" so they decided they should try and repair the problem. The homeowners called EFS for a free inspection. Our Design Specialist James recommended installing Push Piers, Geolocks, PolyLevel, and Nexus Crack Repair, to stabilize the foundation and foundation walls of the home. 

Our team first pushed 6 Push Piers deep into the ground under the home until they reached sufficient pressure. Next, the team used PolyLevel to fill the void under the basement slab where they just lifted the home. After the team installed 5 Geolocks to stabilize the foundation wall that had a significant crack in it. After everything was secured, the team then sealed all of the cracks in the foundation wall. 

The homeowner was very pleased with the results of the project. The homeowner was very happy they called EFS for this project and used their expertise to stabilize their foundation. 

An owner of a rental property in Manchester, New Hampshire, was reaching out to companies in the area to address the sagging floor in the property. The floors of the building feel very unlevel. The owner called Erickson Foundation Solutions and our Design Specialist Liam recommended replacing the supports in the basement with a combination of Lally columns and SmartJacks to eliminate the sagging in the floors. 

Our production team began by replacing some of the old supports in the basement with new Lally Columns. Once those were swapped out the team then installed 3 SmartJacks with a 6ft Supplemental beam to the front right corner of the home. 

The owners and tenants were very happy with the results of the project. The floors no longer have an obvious tilt to them. 

A homeowner in Bedford, New Hampshire, was in the process of purchasing the home but the home inspector flagged the home for foundation wall issues. The buyer of the home was still interested in purchasing the home from the seller but they had to work together to get the foundation repaired before the sale could go through. The seller and buyer agreed to call EFS for a free inspection. Our Design Specialist Victor inspected the interior and exterior of the foundation and found some cracks that were concerning. Victor recommended installing Helical Piers.

Our production team first began by excavating along the front of the home foundation to expose it. The team exposed the foundation in order to install Helical Piers to support the foundation and prevent further damage. Our team used a hydraulic drive head to screw our Helical Piers into the soil below the home. After pressurizing the piers the team attached a Pier Bracket to the foundation of the home that will hold the pier at pressure and to the home. The team installed 12 Helical Piers and stabilized the Chimney. After all of the piers were installed, the team then backfilled all of the dirt. 

The buyer and seller were happy with the results of the project. 

A homeowner in Manchester, New Hampshire, had a sump pump system installed into their home by North East Basement Systems before they shut their doors. The homeowners were experiencing water entering their basements. So the homeowner tried to reach out to NEBS and they got redirected to EFS and booked an appointment with us. Our Design Specialist Victor looked at the system and where the water was entering the basement. Victor recommended installing 20' of WaterGuard attached to the existing sump pump and a SaniDry Sedona dehumidifier. 

Our production team began by chipping out concrete against the wall where the wall was entering the basement. The team chipped out 20' along the wall and removed enough dirt to insert our WaterGuard into place. Once inserted into the small trench the team lightly covered the WaterGuard with crushed stone. The team made sure to link the WaterGuard to the sump pump so any water collected by the perimeter drain will be guided to the sump. After the drain was linked with the sump the team then mixed some concrete and covered the top of the WaterGuard. Now any water that enters the basement will enter the WaterGuard and be guided to the sump pump where it will be discharged. 

The homeowner was happy that they reached out to EFS for their waterproofing needs. 

A homeowner in Manchester, New Hampshire, had recently purchased a home, and during the repurchase inspection, the inspector noticed some settlement on their front porch. A couple of the supports under the porch were held up by a couple of stacked cinder blocks.  After 4 weeks of living in their new home, the homeowner decided they had to find a solution to repair the settlement of their front porch. The homeowner called EFS for a free inspection and our Design Specialist recommended replacing the supports under the porch with Helical Piers. 

Our production team began by adding temporary support next to the sinking posts. Once the porch was supported the team then removed all of the old supports. Next, the team used a hydraulic drive head to twist our Helical Piers into the soil under the porch. The team made sure the piers were installed straight up and down and at sufficient pressure to sustain the weight of the porch. Once all 4 of the Helical Piers were pressurized the team then attached the bracket that allows us to then attach a wooden support to the porch. The team cut each wooden support the correct size after each bracket was installed over the helical piers. Once everything was installed the team removed the temporary posts and cleaned up the job site. 

The homeowner was happy to know their porch would be settling anymore. 

A homeowner in Manchester, New Hampshire, moved into their home in 2021. Since owning the home they have noticed moisture and cold drafts in their home that was built in 1945. They reached out to EFS for a free inspection and our Design Specialist Victor recommended encapsulating their crawlspace with CleanSpace and reducing moisture with a SaniDry Sedona. 

Our team first began connecting sheets of CleanSpace to encapsulate the crawlspace. The team combined the CleanSpace by using our special CleanSpace Tape to install the CleanSpace and keep it air-tight to encapsulate the crawlspace. The team covered the entire floor and the wall up to the floor joists with CleanSpace to encapsulate the crawlspace. Once the crawlspace was completely encapsulated, the team then set up a SaniDry Sedona. The team installed the SaniDry in between the crawlspace and basement to control the moisture in both areas. 

A homeowner in Manchester, New Hampshire, had purchased their home in 2021 and was planning on fixing up the 91-year-old home. When the homeowner bought the home about a year ago they noticed that some of the floors were sagging. The homeowner had noticed the symptoms of the sagging starting to show up on the outside of the home. The homeowner decided to call EFS for a free inspection and our design specialist recommended installing two auxiliary walls, SmartJacks, and a concrete slab pour into their basement. 

Our production team began installing SmartJacks in the basement. The team installed 6 SmartJacks with 14' of supplemental beam to help stabilize the floors. The team installed the SmartJacks using our big plate footings. Underneath each big plate, the team had installed a layer of engineered fill to help stabilize the SmartJacks. After 6 of the SmartJacks were installed, the team adjusted the SmartJacks to make the floor above level, then the team called in a concrete truck to fill the basement with a couple of inches of concrete so they have a basement floor instead of a dirt floor. Next, the team began prepping for the installation of the Auxiliary Wall. The team used a combination of PowerBraces, rebar, and metal wall forms to make a form for the Auxiliary Wall. Once the two Auxiliary wall forms were set up the team called the concrete truck back to fill up the forms to create the Auxiliary Wall. The team then had to wait for the concrete to fully cure before they could remove the forms. Once cured, the team removed the wall forms and chipped off any imperfections on the concrete.

Now the homeowner has stable floors and foundation walls in their home. The homeowners were thrilled that they no longer have to worry about the foundation walls or the floors in their home. 

A contractor in Manchester, New Hampshire, purchased a home in late 2020 that had a fire on its top floor. The homeowner wanted to gut the top floor to repair items that were damaged by the fire. Other than the fire damage in the home, there were also some floor support problems. On the first and second floors, the floors were sagging and sloping. The homeowner plans on repairing the home to rent out the top floor as two rental income units. Our design specialist Michael B. recommended replacing the old supports in the basement and adding more supports. 

Our production team replaced and installed 6 lally columns into the basement. To install the lally columns, the team first installed temporary supports around the basement to keep the beams and floors in place when they replace the old lally columns. Once the temporary supports were set up and the old supports are removed, the team began prepping for the new lally columns to be installed. The team chipped out 24" by 24" sections of concrete to install each lally column. Each section that the team chipped out is so the lally column doesn't rest on the slab in the basement. The team chipped through the slab until they hit the dirt. After they reached dirt, the team poured in a concrete base that the lally column can rest on. The team sets the bottom of the lally column on the concrete and connected the top to the beam above. After the lally columns were installed, the team poured concrete over the base to prevent them from moving or shifting. 

The homeowner was happy that EFS stopped the sagging and sloping in their home. Now they can focus on repairing the second floor so the homeowner can transition that space into two rental units.
