Alton, 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 Alton, NH
Add Supports and Waterproofing into Basement, Alton, NH

A homeowner in Alton, New Hampshire has owned their property for over a decade. Recently, they observed that the basement supports were no longer holding up the floor system as effectively as before. They contacted Erickson Foundation Solutions to inspect the basement. Jason Vachon, our Design Specialist, met with the homeowner and thoroughly inspected the basement to identify any underlying issues. Jason determined that aside from installing new supports, the basement had an unacceptably high moisture level. To address this issue, Jason recommended installing a TripleSafe and a SandiDry Sedona Dehumidifier in the basement.


Eric Witham led our Installation Team, who began by setting up temporary posts in the basement to remove the old supports. The team then constructed three footings on the basement floor to accommodate our big plate footings for our SmartJacks. Once the footings were installed, they set the SmartJack supports into the footing and attached our adjustable bracket and Supplement beam to support the floor system. After installing the SmartJacks, the team installed the TripleSafe in the lowest corner of the basement to collect water and pump it out before it entered the basement. Following the sump installation, the SaniDry Sedona was installed next to the sump. The dehumidifier takes moisture out of the air, and then the discharge line feeds right into the sump pump basin, making it unnecessary to empty the dehumidifier.


The homeowner was very satisfied with the project's results. They no longer have to worry about the floor system or water entering their basement.

Foundation Settling, Alton, NH

A homeowner in Alton, New Hampshire, was the first owner of their home that was built in 1987. A few months ago they had started to feel like their 1st and 2nd floors were settling. They decided to call EFS and get the foundation looked at by some experts. Our Design Specialist Jason inspected the home and recommended installing 7 Helical Piers to stabilize the foundation and chimney and NexusPro to seal any cracks. 

Our team began by exposing the footing of the foundation from the basement. Once the foundation was exposed, the team drove in our Helical Piers until they reached a predetermined pressure by project managers. Once our piers were at the correct pressure the team then inserted our bracket over our pier and then secured the pier to the footing of the foundation. Once capped and secured the team then covered the piers with dirt and repoured the concrete they chipped out. While the concrete was curing the team sealed 20' of cracks with NexusPro. 

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

Radon Levels Increasing, Alton, NH

A homeowner in Alton, New Hampshire, had lived in their home for an entire year. Before they moved into their home it was tested for radon. The levels were around tested 5.5 pCi/L in December 2021. Then in February 2023, the homeowner decided to test the house again to see if anything had changed. The test results came back at 7.1 pCi/L. With the radon levels increasing the homeowner decided to call EFS for a radon appointment. Our Design Specialist Jason recommended installing a Radon Mitigation System in the home's basement to collect radon air from beneath the house and push it out of the home and into the open air. 

Our Installation Team began by creating an extraction point in the basement. The team cut a circular hole in the corner of the basement so we could fit PVC pipe into it. The PVC pipe will carry radon-filled air to the radon fan. The team installed the radon fan on the exterior of the home. The fan will draw the radon from beneath the home and into the PVC pipe and then push it out above the roofline. 

The radon system we installed was able to reduce the radon levels in the home to below 4.0 pCi/L. The homeowners were very pleased with the results of the project.
