Exterior Waterproofing Hamilton, Excavation, Membrane & Weeping Tile Solutions
For chronic water intrusion, foundation cracks combined with moisture problems, or basements where interior fixes haven't held up, exterior waterproofing addresses the issue at its source, outside the foundation wall, before water ever gets the chance to enter your home. Ontario Foundation Group is an exterior waterproofing contractor Hamilton, Ontario homeowners trust for the more involved job done right the first time.
Exterior waterproofing stops water before it reaches your foundation wall — the most thorough solution, but also the most involved, since it requires excavation. It's the right call for severe water intrusion, foundation cracks needing repair, or older membranes that have simply worn out. We will tell you honestly whether your home needs the full exterior job or whether interior waterproofing would solve it for less.
Professional Solutions for All Exterior Waterproofing Issues
Exterior waterproofing is the most comprehensive solution available for basement water problems, and it's typically the right call when water intrusion is severe, recurring, or tied to foundation cracks that need repair alongside waterproofing. The process involves excavating around the affected section of foundation, applying a waterproofing membrane directly to the exterior wall, installing or replacing exterior weeping tile, and properly backfilling once the system is in place. Our exterior foundation waterproofing Hamilton,n Ontario team handles every step of this process, from the initial excavation waterproofing Hamilton homes require through to final backfill and grading.
This is a bigger job than interior waterproofing, and we're upfront about that, but for the right situation, it's a permanent solution that addresses the problem rather than managing it from the inside indefinitely.
