Exterior waterproofing Collingwood homeowners trust protects the foundation from the outside, where water problems actually start. GDS Landscaping and General Contracting excavates to the footing, cleans and repairs the wall, seals cracks, applies a waterproof membrane and drainage board, installs new weeping tile and backfills with grading that sheds water away from the house. If your basement is damp, the assessment is free. Visit our Collingwood landscaping page and our main exterior waterproofing page to learn more.

Our Exterior Waterproofing Process
- Excavation and inspection. We dig down to the footing and get an honest look at the foundation wall and existing drainage.
- Surface preparation and crack repair. The wall is cleaned and every crack and vulnerable point is sealed before waterproofing.
- Membrane application. A waterproof membrane and drainage board are applied to shield the wall and channel water downward.
- Weeping tile and drainage. New perimeter drainage is installed and connected to a sump or storm outlet, moving water away from the home.
- Backfill and grading. Soil is replaced carefully and the finished grade is shaped to slope away from the foundation.
Skipping steps is how waterproofing fails early. Membrane alone cannot hold back water with nowhere to go, and new drainage alone cannot seal a cracked wall. We build the complete system, in sequence, with one crew accountable for the result.
Built for Collingwood & Georgian Bay Conditions
Between Georgian Bay and the Niagara Escarpment, Collingwood homes see lake-effect snow, rapid spring melts and soils that can hold water against a foundation. Clay-heavy ground makes drainage more important, not less, and freeze-thaw cycles widen small cracks year after year. Sloped lots near the escarpment add runoff that has to be managed at the surface as well as below it. Our waterproofing is designed for these local conditions, whether the home is a downtown century house, a newer subdivision build or a four-season property near Blue Mountain.
What’s Included in Exterior Waterproofing
- Foundation waterproofing membranes. A seamless protective barrier on exterior foundation walls.
- Weeping tile installation and replacement. Perimeter drainage that carries groundwater safely away.
- Sump pump installation. Extra protection where water tables or lot conditions demand it.
- Foundation crack repair. Cracks sealed correctly before they turn into leaks.
- Grading and drainage correction. Re-sloping soil so rain and meltwater move away from the house.
- Window well drainage. Preventing basement window wells from filling and leaking.
Signs Your Collingwood Home Needs Exterior Waterproofing
- Water stains or damp patches on basement walls
- White, powdery efflorescence on concrete surfaces
- Persistent musty odours in the basement
- Visible cracks in foundation walls
- Pooling water against the house after rain or melt
- Window wells that collect water instead of draining
These are early warnings worth acting on. Exterior waterproofing protects finished basements, stored belongings and the foundation itself, and it is far better than repeatedly repairing interior water damage. See our project photos page for examples of our workmanship.
What to Expect During the Work
Before excavation begins, we walk the property with you and agree on the walls being treated, equipment access, how excavated soil will be managed and how nearby decks, walkways, driveways and plantings may be affected. As the foundation is exposed, we inspect it together in effect: if the wall or drainage shows something unexpected, we explain it and your options before proceeding. Once the membrane, drainage board and new weeping tile are in place, we backfill carefully and restore grading so surface water moves away from the house. We finish with a walkthrough of what was installed at each stage, because most of a waterproofing system is invisible once the soil is back, and you deserve to know it was built properly.
A Local Note for Collingwood
Collingwood’s four-season lifestyle means homes work hard all year, from heavy snow loads to spring runoff coming off the escarpment toward Georgian Bay. Properties used year-round, and those that host family and guests through ski season and summer alike, cannot afford a basement that smells musty or floods at melt. Older downtown homes may have drainage that has simply reached the end of its life, while newer builds can suffer from settled backfill that quietly slopes water toward the wall. Assessing the foundation and grading before finishing, or re-finishing, a basement is the smart sequence, and it is exactly what our free assessment is for.
