Reliable Basement Waterproofing & Foundation Repair Professionals in Fairfax County, VA

Gail O. was experiencing water issues in her unfinished basement. In her search for a solution, she called NV Waterproofing & Foundation Repair. Mauricio Carvalho went out to give her an idea of ways she could mitigate her water problems permanently. 

He proposed the installation of a TripleSafe sump pump, accompanied by a CleanSpace Wall System, and WaterGuard. The CleanSpace wall system is a clean and durable vapor barrier for basement walls that helps to prevent water vapor from permeating into the basement, as well as draining any wall leaks that occur. WaterGuard is a piping system that intercepts water that appears along the perimeter of the basement and reroutes it back to the installed sump pump. All of these solutions work together to keep the basement dry and water free. 

With these systems in place, Gail O. will be able to enjoy a dry, clean basement in her forever home for many years. NV Waterproofing & Foundation Repair is glad to have been able to finally solve Gail's reoccurring water issues.

Seema was very happy with the results of the repair once again.
