Signs of Foundation Water Intrusion
Common warning signs include damp basement walls, peeling paint, staining, moisture after heavy rain, visible foundation cracks, musty conditions or water entering at wall penetrations. The right repair depends on the source and exterior conditions, so we start with an on-site assessment rather than assuming every leak needs the same solution.
Our Waterproofing Process
- Inspect the affected interior and exterior areas.
- Identify accessible cracks, penetrations, grading concerns and likely entry points.
- Define the excavation, surface preparation, waterproofing and restoration scope.
- Prepare the foundation surface and complete the agreed waterproofing system.
- Protect the treated area, backfill where applicable and clean the site.
