Backfill and membrane install along a foundation

Exterior Waterproofing in Durham Region

Foundation membrane, crack sealing, grading correction and drainage. The fix the basement actually needed.

  • Full excavation to footing
  • Membrane & drainage board
  • Weeping tile replacement

Overview

How we handle exterior waterproofing

We excavate to the footing, apply waterproof membrane, install weeping tile, and backfill with clean gravel. We address the root cause, not just the symptom.

Most basement leaks are caused by failed or non-existent exterior waterproofing. Interior solutions manage the water after it's already inside. We stop it from getting in.

FAQ

Frequently asked questions

Do not see your question? Call us at (289) 928-8206 and we will talk it through.

What's the difference between interior and exterior waterproofing?

Interior systems manage water after it's already inside. Exterior waterproofing stops water at the foundation wall before it enters. We always recommend addressing the root cause from the outside.

Will you need to dig up my landscaping?

Yes, we excavate along the foundation wall. We backfill and re-grade after, and can coordinate sod or garden restoration as part of the same project.

Do you install French drains?

Yes. French drain installation is part of our drainage work, alongside grading correction. We confirm the right fix for your yard during the on-site quote.
