Crawl Space Repair Photo Album: Concrete Crawl Space Upgrade - Chatham, ON

In this project, we transformed a damp, inefficient concrete-floor crawl space into a clean, dry, and energy-efficient environment. Our crew removed the failing fiberglass insulation from the foundation walls and installed perimeter drainage leading to a new sump pump. We added a powerful SaniDry Sedona dehumidifier to control moisture and improve air quality after the CleanSpace Encapsulation system was put down on the floor. The foundation walls and headers were then insulated with spray foam for long-term efficiency and sealed with DC315 thermal barrier paint for added safety and code compliance. All work was completed by our in-house team—no subcontractors. A great example of how Advanced Basement Systems delivers full-service crawl space solutions from start to finish.

Before

A thin concrete floor sits over the dirt beneath it. Fiberglass, or blanket-wrap, insulation is on the walls. This type of insulation on foundation walls is one of the worst things you can have in a basement or crawl space!

Encapsulation

After we installed an interior footing drain around the perimeter of the space, our CleanSpace is installed on to the floor, and mechanically fastened to the walls.

Half-Way

We also have to wrap and seal the support columns! Although this space looks tight, this crawl space offers more headroom than the average in our area.

Sump Pump and Back-Up

Our CleanSpace is sealed to the sump liner, and the two-piece lid helps maintain an airtight seal. We have our UltraSump Battery Back-Up system here- because crawl spaces can flood, too!

Spray Foam and DC315

That's a wrap! The spray foam has been correctly applied, at 3" thick. The sump's discharge line is done and the DC315 paint has dried.

SaniDry Sedona Dehumidifier

The best crawl spaces have this- our Sedona Air System. It's primary focus is keeping humidity at a stable level, but it also helps filter the air and condition the space!
