Merrimack, 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!

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 Merrimack, NH
Slab Under Addition Is Cracked and Sinking, Merrimack, NH

A homeowner in Merrimack, New Hampshire, had an addition that was installed on raised supports and the supports were set on a concrete slab. The home was built in the 1950s and the newest homeowners have lived in the home for 2 years. Since they purchased the home the homeowners noticed the addition at the back of their home was being supported by cracked concrete. With young kids running around the homeowners have had to tell their kids not to go into the addition because they fear it will collapse. Our design specialist Chris recommended removing the concrete under the additions and installing 6 EZ posts underneath the structure. 

 Our production team started by removing the concrete from under the addition. To make sure the addition didn't collapse the team set up temporary supports. The team removed the concrete and the old supports from the addition and began setting up the EZ posts. The team used a hydraulic drive head to drive down our EZ post into the ground. The team drove down each EZ post until they achieved a high enough PSI to support the addition. The team then capped each of the EZ posts with an adapter that will hold a PT 6x6 support. The team finished by securing each of the EZ posts to the addition to fully support it. 

The homeowners were very happy with the results of the project. They can now use the back room of their home for the first since purchasing the home 2 years ago.

Covered Porch Needs Support, Merrimack, NH

A homeowner in Merrimack, New Hampshire, had a covered porch off of the back of their home. They deemed the covered porch no longer safe to stand in because of fear that it will collapse. The concrete piers under the main beam were sagging while some other supports around the porch were doing nothing at all. The homeowners would like to have the supports under their covered porch replaced so they can use that space in their home again. Our design specialist Chris recommended installing 6 EZ posts to replace the old sinking concrete piers. 

Our structural team began installing temporary posts and carefully removing the old concrete piers from under the covered porch. The team installed EZ posts in place of the old concrete piers. They installed the EZ posts by using a drive head to drill down the post like a big screw. The team made sure that each post was installed straight and under enough pressure to stabilize the covered porch. The team disposed of the old concrete piers and secured the EZ posts to the vertical supports of the covered porch. 

Our team installed EZ posts under the homeowners' covered porch to replace old sinking concrete piers that had lost their structural integrity. The team supported the main beam with 3 EZ posts and also added support where 3 concrete piers had failed with 3 more EZ posts. The homeowner was very happy they were able to use their covered porch. 

Concrete Needed Repair in Warehouse, Merrimack, NH

A warehouse in Merrimack, New Hampshire, had some concrete that had cracked on the warehouse floor. The cracking had gotten bad enough to cause a tripping hazard. The warehouse had forklifts that operated on the warehouse floor and the manager would like to have the floor repaired. Our design specialist Michael Bradley examined the areas of cracked concrete and recommended removing and replacing the cracked concrete, using PolyLevel to fill the void under the concrete, and using NexusPro to seal cracks around the warehouse. 

Our PolyLevel team led by Tyler, first started by chipping out the damaged section of concrete. Once the concrete was removed, they installed rebar to strengthen the concrete. They then poured the new concrete over the rebar and waited for it to cure. As the concrete is curing, the team went around the warehouse to inject PolyLevel under the concrete to fill void. After the team filled the void, they used NexusPro to seal all of the cracks around the warehouse.

Home Buyer Needs Crawlspace Fix, Merrimack, NH

Tim H. of Merrimack, NH was looking into purchasing a home, and after taking a look in the crawlspace himself, decided he wished to have a professional take a look to determine any major concerns. He contacted Erickson Foundation Supportworks, and confirmed he was satisfied with the pre-purchase fee involved for home buyers. This was a home he was very interested in buying, and so the investment in the inspection was worth it. In the end, he did purchase the home, and so the pre-purchase fee was credited back to him.

Upon inspection, Erickson's System Design Specialist, Brian Allen, saw it was immediately evident there was settlement action throughout the crawlspace. The home was built in 1986, and over the years the space must have fluctuated between being high in moisture and very dry. The floor had settled any where from 2 feet to just a few inches, and so was very uneven and unstable. The lally columns supporting the main beams and floor joists were no longer stable, some having settled several inches along with the soils.  Temporary wood shims had been added to the beams over the years, and a more permanent fix was desperately needed. 

The repair system Brian designed required 11 Smart Jacks to support the beams, as well as PolyLevel to raise the garage slab, and several Push Piers to stabilize and potentionally lift a corner of the homes concrete foundation. As Tim was purchasing the home, he had to decide to focus on the major repairs for the time being, and then address other concerns down the road. The SmartJacks were needed to correct the sloping floors and uneven doors above, and so these were installed immediately. 

The only access point to the crawlspace was a 2' x 2' hole in the floor of a closet on the first floor. Therefore, the crews were required to carry all tools, SmartJacks, and stone material through the house. Each item had to be carefully lowered down into the space, and then carried again to the needed locations. It was an incredible team effort, and although tiring, was a very rewarding project for the crew, as they knew the new home owner was going to have a stable home.

After installation of the SmartJacks, the floors were in good shape, and Tim H. had peace of mind that the property he just purchased was safe and stable.
