Before and After Pictures from Windham
Crack Seal, Windham, NH

Crack Seal, Windham, NH

This homeowner in Windham, NH had a crack in their foundation wall, which had been patched over the years, but still let in moisture. They needed a more permanent fix. We sealed the crack with a polyurethane injection, which expands inside the crack as a foam and reaches far into the cravice to prevent the water from coming through. The surface of the crack is then coated with an epoxy to add an extra layer of protection. This two part system guarantees no further moisture will come in through the foundation crack.

This seasonal cottage on Cobbetts Pond in Windham, NH was suffering from sagging floors, settlement, and unstable soils. Water was constantly running down a hill toward the home and the lake just beyond it. As water flowed through the soil beneath the home, the concrete piers and wood posts settled over time. The home needed more permanent stabilization if it was going to last.


Erickson Foundation Supportworks installed EZ Post helical piers around the perimeter of the home. SmartJack columns were also installed beneath to replace concrete piers and rotten wood posts.

Windham, 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 a technique called 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!

Concrete Wall Repair, Windham, NH

The owner of this property on Cobbetts Pond in Windham, New Hampshire knew when he bought the home that eventually the concrete walls of the boathouse would need to be repaired. There were visible, large cracks on the wall which faced the water. There was slight settlement, and the walls in general were shifting more and more each year. He reached out to a number of foundation repair contractors but in the end found only Erickson Foundation Supportworks had the right team and the right solution. And rather than wait for the situation to get worse, the time had come to fix it. 

Our inspection specialist David Cormier viewed the walls and designed a system utilizing 8 GeoLock wall anchors, as well as 6 Helical Piers. Together these anchors and piers would prevent the walls of the foundation from any further movement. The challenge for the production team was having to work in the frigid pond water in the late autumn months. With the right equipment and a 'can do' attitude, the crew worked diligently to install the system.

The concrete walls of this boathouse are now permanently stabilized, and the homeowner can now continue to preserve this small piece of New Hampshire history.
