Questions

How It Works

  • Can waterproofing be done after the structure is already built and backfilled?

    Yes. Retrofit work typically involves excavating to expose the exterior wall, applying the membrane and drainage board, and improving the perimeter drain. The scope is larger than pre-backfill installation, but the same assembly applies.

  • What happens if I wait and monitor the leak instead of acting now?

    Active water intrusion in Dallas clay soil tends to worsen after each wet season. Water that enters through a crack carries fine soil particles, widening the crack over time. Footing erosion and rebar corrosion are the two most common consequences of delayed repair in below-grade concrete walls.

  • How does Dallas clay soil affect the waterproofing system choice?

    Expansive clay swells when wet and shrinks in drought, creating cyclical lateral pressure against the wall. That movement can shear a rigid membrane, so the site review checks whether a flexible bentonite system or a liquid-applied membrane with a drainage board is the better match for the specific soil profile.
