Alberto B. of Contoocook, New Hampshire has a foundation that is a combination of concrete and fieldstone and the foundation walls have cracks in them. One of the cracks in the fieldstone part of the basement is so bad you can see daylight through the wall. Alberto wants to fix these problems for his kids. He called Erickson Foundation Solutions to see if they could come out and look at his foundation and solve his concerns. 

Design Specialist Royce Potts came to Alberto's home and inspected the foundation. Royce proposed that EFS will install auxiliary walls in the areas of concern.

Crew Lead Jon Provost and his team came to the home and installed 16' of auxiliary wall to the basement.

The sump system also includes a battery back-up for extra security against any power outages.

Contoocook, NH Local Concrete Leveling Expert

Sunken and cracked concrete around your home is not only an eyesore but is also a safety hazard. As time goes by, if the problem isn’t corrected, it will only get worse. However, you have no reason to fret when you have the professionals at Erickson Foundation Solutions doing the work. Our experts use PolyLevel, a strong, and durable foam material to lift your concrete slabs back into place. We drill small holes into the slab where the foam is injected and expands, raising the concrete into place. Many other contractors will use mudjacking, but our method doesn’t disturb the area, takes less drying time, and is more affordable.

After repairing your concrete, consider a durable concrete sealant that extends the life of your slabs by 3 to 5 times overall in just one quick application. Our SealantPro concrete sealant bonds with concrete on a molecular level to protect slabs against oil, gasoline, water, debris, and more. Whether you have new slabs or existing slabs, SealantPro will work for you! We also offer a translucent tinted concrete sealer, DecoShield, which adds a unique visual appeal to your home's slabs while preventing pitting, flaking, cracks, and other moisture-related issues.

Job Stories From Contoocook, NH
Wet Basement Needs Water Proofing, Hopkinton, NH

A homeowner in Hopkinton, New Hampshire had been living in their house for approximately a year. When they purchased the house, the seller assured them that the basement was not prone to flooding. However, after a year of living in the house, they faced basement flooding and discovered signs of mold and mildew. The homeowner had plans to finish the basement in the future but couldn't do so due to the flooding and mold growth. They contacted EFS for a free inspection of their basement. Our Design Specialist, Isaac Hernandez, met with the homeowners, assessed the situation, and proposed a solution. Isaac suggested installing a full perimeter drainage system that included 100' of WaterGuard, a TripleSafe sump pump, 2 IceGuards, a SaniDry Sedona dehumidifier, and a buried exterior drainage line to prevent water from entering the basement and eliminate mold and mildew.


Our Installation Team began by chipping the perimeter of the basement to install the perimeter drainage system and sump pump. They used a jackhammer to break up the concrete into manageable pieces that they could remove from the basement. Once they removed all the debris, our team installed the drainage system and sump pump. Next, the team plumbed the sump pump to the exterior of the house, where they installed two IceGuards and a 10' buried exterior drainage line. After the exterior drainage was installed, the team returned to the basement to pour concrete around the basin of the sump pump and cover the perimeter drainage to lock them into place. Finally, the team placed the SaniDry Sedona dehumidifier next to the sump pump to control humidity levels in the basement and prevent mold growth.


The homeowner was thrilled with the work that Erickson had done in their home. They no longer have to worry about water or mold issues in their basement.

Garage Floor Sinking, Contoocook, NH

A homeowner in Contoocook, New Hampshire, built their home in 2019, and shortly after moving in they noticed a section of concrete in the garage had begun to sink. Over the next few years, they have seen the concrete sink further and further down. The homeowners noticed their doors starting to get tight so they called EFS for a free inspection of their home. Our Design Specialist Isaac examined the slabs in the garage. He used a laser level to determine how much the slabs had sunk. He found that the back right slab in the garage had sunk 2" and the front right had sunk about 1". Isaac recommended installing PolyLevel into the garage to lift and level the slab. Isaac also recommended installing NexusPro to seal the control joints. 

Our installation team began by drilling portholes in a grid pattern around the garage so we could lift and level the slab without cracking it. After the holes were drilled the team then started to inject PolyLevel beneath the slab. The team first filled the void in the areas of the slab that have sunk but then lifted the sections that had sunk. Once the slab was lifted and leveled they then cleaned up any excess poly that had seeped through the cracks. After the poly was cleaned up, the team then used some universal concrete to plug the injection portholes.

The homeowners were very impressed to see our team and PolyLevel in action. They watched their concrete get lifted back to level in a matter of minutes and it was cleared to drive on by the time the team left. 

Cracked Concrete In Garage, Contoocook, NH

A homeowner in Contoocook, New Hampshire, had lived in their home for the past 10 years. They planned to remodel their garage but needed to make sure the slab can be fixed. The homeowners were told by other contractors that they would need to pour a brand new slab. The homeowners then reached out to EFS to see if we could find them a repair. Our design specialist Victor recommended installing PolyLevel and NexusPro to lift, level, and seal the slab in the garage. 

Our production team first started by drilling port holes in a grid pattern into the slab. The port holes gave the team a space to inject PolyLevel under the concrete. The team injected the PolyLevel under the slab to precisely lift and level the concrete. After they lifted and leveled the slab the team then started sealing the cracks with NexusPro. They used a motorized caulking gun to squeeze NexusPro into all of the cracks. To make sure the cracks are sealed the team used a set of metal spoons to push the NexusPro deep into the cracks and to leave a smooth finish. 

The homeowner was very happy with the results of the project. They can finally remodel their garage like they wanted to.
