Lee, 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.

Radon gas is produced from the decaying of rocks and soil and comes up from the ground into your crawlspace and basements. The way our radon mitigation systems works in a pipe collects the gases that are coming from the soil. The gas is then piped upwards where a depressurization vent forces the radon out from your home.

Job Stories From Lee, NH
Cold Floors in Winter Months, Lee, NH

A homeowner in Lee, New Hampshire has lived in their home for over 30 years. During winter, they noticed that the floor on the main level of their home gets very cold. Additionally, they noticed a bounce in the floors, which are over 100 years old, and wanted to address it. They contacted EFS for a free inspection and our Design Specialist, Anthony Brancato, met with them and inspected their basement. Anthony then proposed a solution that recommended insulating the crawlspace with CleanSpace, Drainage Matting, and SilverGlo. He also suggested replacing the existing supports with SmartJacks and installing a SaniDry Sedona dehumidifier to control the humidity in the crawlspace.


Our Installation Team, led by Anthony LoCascio, removed debris from the crawlspace before installing the new support system. 6 SmartJacks were installed to stabilize the 100-year-old floor system. The team then encapsulated the crawlspace, covering an area of 609 square feet with crawlspace encapsulation and 550 square feet with insulation. Finally, the dehumidifier was installed in the basement to control the humidity down there. 


The homeowners were very pleased with the results of the project.

Foundation Wall Is Bowing, Lee, NH

A Lee, New Hampshire homeowner lived in their house for 18 years and noticed a crack in the back wall of their detached garage foundation, which gradually grew larger over 3 years. Seeking a solution, the homeowner contacted Erickson Foundation Solutions for a free inspection. Design Specialist Victor Tapia inspected both the interior and exterior of the garage to identify the cause of the crack. Victor found that the foundation wall at the back of the garage was bowing outward, causing the crack to expand. Our team recommended installing 6 Geolocks on the back wall of the foundation. 

The Installation Team, led by Neal Foley, began by drilling 6 small holes evenly across the foundation wall. After chipping out a trench 10' away from the foundation, parallel to the foundation wall, the team secured a galvanized rod through the foundation wall and into the trench. We attached a Geolock Anchor to each side of the rod. Once the Geolocks were secured, the team tightened them to straighten the foundation wall. Once the wall was stabilized, the team backfilled the trench and mixed up concrete to repour where we chipped out concrete from the slab. 

The homeowner was delighted with the results, no longer worrying about the foundation wall of the garage.

Repair Moisture and Water Before Remodeling Basement, Lee, NH

A homeowner in Lee, New Hampshire, planned to remodel their finished basement. The basement currently had high moisture and water coming in. The homeowner wanted to stop the water from coming in and reduce the moisture in the basement before they start remodeling the space. Our design specialist Brian recommended installing FlexiSpan, an UltraSump, Ice Guard, WaterGuard, and a SaniDry into the basement to stop the water and moisture from entering the basement. 

Our waterproofing team began by setting up a trench for the WaterGuard perimeter drainage system. The team used a jackhammer to chip out 42' of concrete big enough for our WaterGuard to be installed. The team fed the WaterGuard through the trench, they made sure to lead the WaterGuard to the area where we were installing the UltraSump. To install the UltraSump the team dug a basin big enough, then the team laid the sump pump into the basin and plumbed it. After the team plumbed the UltraSump they poured water down the WaterGuard to see if the water would collect in the sump and test the pump. After the team verified that the sump and perimeter drain worked, they moved on to seal a crack in the foundation that was allowing water into the basement. The team used FlexiSpan to seal the crack on the foundation wall. The FlexiSpan will act as a channel to collect the water that was entering through the crack and guide it into the perimeter drainage system. After the FlexiSpan was completed the team poured concrete over the WaterGuard and around the UltraSump basin to conceal it. The final step after the concrete cured was to install the SaniDry Sedona and connect its discharge line to the UltraSump. 

The homeowner is happy they can proceed with remodeling their basement without worrying about water entering their basement.
