Below Grade Water Proofing

Frequently asked questions
What does below-grade waterproofing cover?
It's the membranes and coatings applied to foundation walls and structures at and below ground — foundation walls, blind-side applications, tunnels, fountains, and roofing — as part of the building envelope.
Can you stop water that's already coming through?
Yes — depending on the situation we combine waterproofing membranes with crack injection (urethane or epoxy) to seal active leaks and keep water out.
What is blind-side waterproofing?
It's waterproofing applied before the foundation is poured — against the earth-side form or shoring — when there's no access to the outside of the wall later. We handle these applications.
Do you waterproof above grade too?
Yes — we handle both above- and below-grade waterproofing as part of the complete building envelope.
