Crawl Space Waterproofing & Encapsulation
Crawl space waterproofing controls ground moisture and humidity through drainage, vapour barriers and full encapsulation. We diagnose the moisture source and design a system to keep the space dry.
Inside a Crawl Space Solution System
Hover over each component to see how drainage, encapsulation, and humidity control work together to keep your crawl space dry.
System Component
Crawl Space Drainage
Where water enters the crawl space, dedicated drainage channels and a sump pump collect and safely route groundwater away before it causes moisture issues.
Where water enters the crawl space, dedicated drainage channels and a sump pump collect and safely route groundwater away before it causes moisture issues.
- Perimeter channels collect seepage at the footing
- Sump pump discharges water away from the home
- Prevents standing water and saturated ground
Encapsulation seals the entire crawl space with bright, commercial-grade liners across the floor and walls, isolating your home from ground dampness and humid air.
- Seals floor and walls with a continuous liner
- Isolates the home from ground moisture
- Bright, clean, serviceable finished space
Polyethylene sheets prevent ground moisture from evaporating into the air. Seams are completely sealed and mechanically fastened for longevity.
- Reinforced liner resists punctures and tearing
- All seams taped and sealed airtight
- Mechanically fastened for long-term hold
A dedicated dehumidifier provides ongoing moisture control, keeping the crawl space dry and protecting the air quality of the home above.
- Sized to the crawl space volume
- Drains directly to the sump or condensate line
- Maintains healthy humidity year-round
Signs of Crawl Space Moisture
Common indicators of crawl space moisture include:
- Standing water or damp ground
- Musty odours in the home
- Mold or mildew growth
- High indoor humidity
- Sagging or damp insulation
- Wood rot or moisture damage

Benefits of a Dry Crawl Space
A properly managed crawl space offers several benefits:
Step-by-Step
Installation Process
Crawl space waterproofing follows a clear, systematic process from diagnosis to final humidity control:
Inspect & Diagnose
Identify exact moisture source and groundwater entry points.
Install Drainage
Set perimeter channels and sump pump system where needed.
Prep Surfaces
Clean, level, and prepare ground and foundation walls.
Ground & Wall Barriers
Lay reinforced ground vapour barrier and mechanically seal wall liners.
Seal Vents & Humidity Control
Seal foundation vents and add a dedicated dehumidifier for ongoing moisture control.
Final Walkthrough
Verify system performance and provide written completion report.
