Below-Grade Entry
Below-Grade and Foundation Water Entry
Below-grade water can come from groundwater, surface drainage, a failed membrane or a plumbing line. Telling them apart decides whether the fix is drainage, waterproofing or a pipe repair.
Symptoms we're called for
- Damp or wet basement walls and floors
- White efflorescence or peeling paint below grade
- Crawlspace humidity and odours
- Water after heavy or prolonged rain
Property types
- Basements and crawlspaces
- Retaining walls and parkade walls
- Elevator pits and utility rooms
Methods used
- Moisture mapping of walls, floors and joints
- Drainage and grade assessment
- Pipe and drain testing to separate plumbing from groundwater
- Dye and flood testing where suitable
Limitations, stated plainly
- Distinguishing groundwater from plumbing requires testing, not opinion
- Exterior excavation is not part of detection
- Repairs are performed by waterproofing, drainage or plumbing contractors
What you receive
- A moisture and entry-path map
- A classification of likely water sources
- Repair and drainage recommendations
Next steps
- Correct drainage and grading where implicated
- Repair plumbing sources first if confirmed
- Verify with a follow-up scan after the next rain
