Crack & Leak Repair

A leaking crack is your foundation’s open door for water. We seal it from the inside with injected resin that bonds deep into the wall — flexible, watertight, and built to stay that way.

What it is & why it matters

Understanding crack & leak repair

Not every crack is structural, but almost every crack that leaks deserves attention. Water working through a crack erodes your foundation, invites mold, and only widens the gap over time.

We repair it at the source. After cleaning the crack, we set injection ports and fill it completely with a professional-grade polyurethane or epoxy that penetrates the full depth of the wall. Polyurethane stays flexible to handle natural movement, while epoxy restores strength where the crack is structural. Either way, the leak stops.

If a crack is leaking, it’s also slowly growing. Sealing it now is far simpler than the repair it becomes later.
