Foundation Repair & Radon Mitigation Contractor in Belknap County, NH

Mark and Marianne of Laconia, NH purchased their home in 2019. About 6 months ago they were worried about clean air to breathe in their basement office. They thought about getting a test done for radon. They got a self-test machine and tested for radon themselves. After seeing that their self-test machine came back with an unhealthy pCi/l range of 4.1- 6.2, they decided to call the experts. A healthy range of pCi/l is under 4.0 pCi/l.

Mark and Marianne got in contact with Erickson Foundation Supportworks to set up a quote and an install of a Radon Mitigation System. Paul Magowan provided an accurate quote and designed a Radon Mitigation System for their particular home. Scott Crandall led the team that installed the Radon Mitigation System into Mark and Marianne's home.

This homeowner of 2 months in Gilmanton, New Hampshire had an issue where the foundation under their two-car garage was beginning to crack and starting to become uneven. The homeowners are hoping to fix and flip the house. In the foundation, multiple cracks were greater than one inch and would likely suffer integrity issues in the future if this went unfixed. They want this fixed so that the garage is functional again to park their car inside and hopefully be able to flip the house. 

They called Erickson Foundation Supportworks because they wanted a company that communicates with them, delivers a quality product, and good pricing. After they called Erickson Foundation Supportworks, a Design Specialist, Paul Magowan came out to Gilmanton and looked at the house and inspected the customer's concerns. Paul inspected the garage and the area around and under the garage to get a broad overview of how the Erickson Foundation Supportworks team would fix the problem. He concluded that they would need to install PowerBrace into the basement under the garage to make the foundation stronger, then they would need to set up a second appointment to pour a new concrete floor in the garage and inject and seal all the cracks. Team Lead Scott Crandall was in charge of install for both appointments. He and his team were able to successfully install the PowerBrace into the basement beneath the garage. PowerBrace is a metal rod that is the height of the foundation wall that is secured at both the bottom and the top of the wall to keep the wall from bowing and also keeps the wall secure. During the second appointment, the team installed the new garage floor and sealed all the cracks.

Wanakee is a youth summer camp that has been in operation since the 1960's. Over the years the property and camp program have developed and expanded. In 2017, the camp built a new shower and bath house on the side of a hill on the property. While the building itself was unique and well built, within a few years the foundation it sat on was cracked and severely bowing in due to pressure from the saturated soils on the exterior of the wall. As water flowed down the fill, it smacked directly into the structures foundation wall, threatening to complete push it in and destabilize the entire building. 

Erickson Foundation Solutions identified the problems with the situation, and installed a water drainage system within the soil along the foundation wall. The system diverted all the water around the building, and so the soil would no longer build up pressure and push against the wall with such high force. The other solution was to install 8 GeoLocks along the cracked and bowing wall, to fully stabilize it against further movement. Once these were in place, the production team also installed 8 Push Piers to permanently stabilize and slightly lift the foundation wall that settled.

Lastly, beneath the main beam of the bath house that ran directly down the center within the crawlspace, 3 SmartJack support posts were installed to lift and level the floor system. 

With the structure stabilized, the camp no longer has to worry about the building's foundation failing or putting any of the campers at risk.

Our production team began by removing the supports that were installed by the other contractors. After the old supports were removed the team then began setting up to install our SmartJacks. First, the team created a flat surface that our SJ footings will rest on. Once the team installed each footing and made sure they were leveled and then installed the supports and the top brackets. Once all connected the team attached the top brackets to the main beam above. The team installed 5 SmartJack under 3 different support beams in the crawlspace.

This homeowner in Center Barnstead, NH was concerned about the cracks in their garage concrete floor. The cracks were visible throughout the concrete slab, and even within some of the walls. There were clear signs of settlement in the garage section of this home. 

Beneath the slab, a large void had formed, which meant much of the slab was not supported or stabilized, leaving it at risk of further cracking and settlement. If left unfixed, the problem will only get worse over time. 

The ideal solution for a slab with void concerns like this is PolyLevel. This polymer foam product is injected beneath slabs to stabilize and lift concrete, and is a great alternative to the more costly approach of completely replacing the slab.
