Foundation Waterproofing

Foundation Waterproof Services in Seattle & Western Washington

The Pacific Northwest has prolonged periods of rain that saturate the ground causing very slow drainage. As water pressure in the soil surrounding the building grows, water seems to find even the smallest crack that presents the least resistance.​

Trinity Waterproofing installs several proven systems of foundation waterproofing:

  • Bentonite Clay Mats:
    These mats look similar to blankets that are hung on the wall. If moisture is present on the side of the foundation, the clay will swell and fills the voids in the wall.
  • Bituthene Self-Adhered Membrane:
    This is a peal and stick product that sticks directly to the wall.
  • Modified Bituminous/Asphalt Emulsion:
    This is a spry applied monolithic system that is fully adhered to the foundation wall.
