This customer in Coventry, RI called us to take a look at a large crack across their garage floor that seems to be contributing to the floor sinking. The customer also noticed an almost hollow sound. We took a look and found this to be a perfect situation for PolyLevel injection foam! Our System Design Specialist, Tyler Damon, recommended PolyLevel to be injected in two areas: Area 2- 10x17x2 109 lbs and Area 1 26x10x3 250 lbs. This will certainly stabilize the flooring and we will seal that crack and the injector ports to get the foam underneath the foundation. The homeowners won't have to deal with days of work, an unusable garage, a ghastly smell, or any toxic fumes. PolyLevel is an incredibly fast product to install and it is non-toxic!
