    Sinking concrete slabs are a huge tripping hazard, especially when they are right at your front door like this homeowner in Conestoga, PA. They called BQ Basement Systems because they did not want to totally replace his porch. We informed the homeowners of our simple noninvasive concrete repair system. After agreement, our crew installed our PolyLevel concrete repair system which lifted and leveled his concrete porch back to its original safe height. After the concrete was lifted our crew caulked and sealed the concrete to prevent moisture from seeping under the concrete in the future. This happy homeowner now has a permanently stabilizing concrete entrance!
