Exterior Waterproofing in the GTA

Exterior Waterproofing, Done Right the First Time

Exterior waterproofing means excavating down to the footing, sealing the foundation wall itself, and correcting drainage before backfilling, which addresses the source of the problem rather than the symptom.

It's more invasive than interior systems, and it's also the more permanent fix when a foundation has ongoing water intrusion through the wall itself.

What's Included

• Excavation to the foundation footing
• Foundation wall crack repair and sealing
• Membrane and drainage board installation
• Weeping tile replacement and backfill
