Above and Below Grade

Commercial Waterproofing That Protects From Every Angle

Water finds the weak point in any building, eventually. Below grade, we waterproof foundation walls so moisture never gets a foothold in the first place. Above grade, we protect balconies, plazas, parking decks, and rooftop terraces from the kind of wear that comes with heavy foot and vehicle traffic. Different problems, same goal: keep water out and keep your maintenance costs down.

Most buildings need both above and below-grade protection at some point, and most contractors only do one or the other. We do both, which means one inspection, one plan, and one team accountable for the whole picture.

  • Below-grade foundation waterproofing
  • Above-grade balconies, plazas, and decks
  • Heavy foot and vehicular traffic surfaces

Stop water damage before it starts.
