NV Waterproofing Before & After
  • Exterior Waterproofing of Front Stoop in Mc Lean, VA
    Exterior Waterproofing of Front Stoop in Mc Lean, VA

    Exterior Waterproofing of Front Stoop in Mc Lean, VA

    Water was entering this Mc Lean, VA home via the front stoop and traveling down the foundation wall into the basement. In the before photo, you can see the evidence of water damage going down the back wall. We exposed this wall to the base of the footer and applied a liquid rubberized waterproofing sealant and drain board. This ensures that there will be no future water issues.

    Basement Makeover in Southeast D.C.

    We recently completed this basement waterproofing project in the District to rid the homeowner of their water issues once and for all. After removing the old existing sump pump and pit, we installed a nice, bright CleanSpace vapor barrier, our WaterGuard perimeter system, and a new UltraSump. This will insure that they have a healthy, dry basement for years to come!
