Job Stories From Deer Isle, ME
Crack In Deer Isle, ME, Basement Sealed With FlexiSpan

Jeff from Deer Isle had a crack in the wall of his Basement. Once he noticed water was spilling in through this crack, he had to have something done to fix it. Jeff took to the internet to find a solution for this problem. He came across TC Hafford Basement Systems, and knew we were the ones for the job.

After being contacted, we had a representative take a look at the crack to see what the best solution was. Once decided, our crew got to work installing FlexiSpan. The first part of this process is to inject the crack with a sealant. This sealant is the first of three layers that make up FlexiSpan. Secondly, we apply a foam matting over the sealant, which acts as barrier for any water that makes it by the sealant. Finally, a second layer of sealant is placed over the foam, sealing it against the crack. This procedure locks out any moisture from trying to enter through the crack, keeping the basement try in three steps. The structure of the FlexiSpan also allows it to contort, should the wall shift at all. Maintaining the seal.
