Foundation waterproofing & drainage

Interior patches treat the symptom. We dig to the footing, repair cracks, membrane the wall, install drain board, and re-route water around the foundation — the right way to stop a wet basement.

FAQ

Common questions

  • Exterior is the only one that stops water from reaching the wall. Interior systems (interior weeping tile, sump pumps) manage water once it's already inside. If you can dig, dig.

  • One wall is typically 2–3 days. Full perimeter is 5–8 days depending on access and depth.
