Warning signs to waterproofing issues in a basement are many. We have listed typical ones:
- Damp floor, visible water, flaky basement walls.
- Mold and musty smell that never goes away.
- Cracks on the floor or walls can signify water buildup.
- A sump pump that never runs can mean that the ground water is not entering the drainpipe underneath your basement, either because it is damaged or blocked. It could also be because the drainpipe is not pitched enough.
