Foundation waterproofing Mississauga homeowners trust is essential for preserving both structural integrity and indoor comfort.

With climate-tested materials and proven techniques, we protect homes and commercial buildings across Mississauga from the damaging effects of groundwater and heavy precipitation.

Why Waterproof Your Foundation?

Water infiltration weakens concrete and mortar, leading to cracks, settling, and ultimately expensive structural repairs.

Avoid Mold & Mildew:

Water infiltration weakens concrete and mortar, leading to cracks, settling, and ultimately expensive structural repairs.

Our Waterproofing Services

Exterior Membrane Systems

Install heavy-duty PVC or rubberized coatings on the outside of your foundation for a permanent moisture barrier.

Interior Drainage & Sump Pumps

Fit perimeter drainage tiles (weeping tiles) behind walls, channeling water into a reliable sump pump system with battery backup.

Crack Injection & Sealing

Inject polyurethane or epoxy resins into cracks to seal leaks under hydrostatic pressure.

Basement Tanking & Coatings

Look for damp spots, efflorescence (white deposits), musty odors, mold growth, or visible leaks after rainstorms.

We use protective measures and efficient excavation techniques to minimize damage—and we restore all disturbed areas afterward.
