When a basement leaks, exterior waterproofing Midland homeowners choose is the fix that addresses the cause: water pressing against the outside of the foundation. GDS Landscaping and General Contracting excavates to the footing, prepares and repairs the wall, seals cracks, applies a waterproof membrane and drainage board, installs weeping tile and backfills with grading that moves water away. It is thorough work, done once and done properly, and it starts with a free on-site assessment. Learn more on our Midland landscaping page and our main exterior waterproofing page.

Our Exterior Waterproofing Process
- Excavation and inspection. We dig to the footing and assess the actual condition of the foundation wall and its drainage.
- Surface preparation and crack repair. The wall is cleaned and cracks and weak points are sealed before waterproofing is applied.
- Membrane application. A waterproof membrane plus drainage board protects the wall and channels water down to the drainage system.
- Weeping tile and drainage. New perimeter drainage carries groundwater to a sump or storm outlet, away from the home.
- Backfill and grading. We backfill carefully and finish the grade so surface water slopes away from the foundation.
Each stage supports the next. A sealed wall without drainage leaves water building against it; new drainage without sealing leaves the cracks that let water in. The complete system, installed in order by one responsible crew, is what keeps a Midland basement dry for the long term.
Built for Midland & Georgian Bay Conditions
Midland sits on Georgian Bay, and its homes handle heavy snow, serious spring melt and clay-heavy soils that hold water against foundations. Freeze-thaw cycles then widen small cracks a little each year, which is why a basement can stay dry for years and then start leaking seemingly out of nowhere. Older homes in town may have original weeping tile that has clogged or collapsed, and grading that once sloped away can settle toward the house over decades. We build every waterproofing system for exactly these conditions.
What’s Included in Exterior Waterproofing
- Foundation waterproofing membranes. A seamless protective barrier applied to the exterior foundation walls.
- Weeping tile installation and replacement. Proper perimeter drainage that carries water away from the home.
- Sump pump installation. Dependable protection where water tables run high.
- Foundation crack repair. Sealing cracks before they become active leaks.
- Grading and drainage correction. Reshaping the ground so water flows away from the foundation.
- Window well drainage. Keeping basement window wells dry and draining.

These signs deserve a proper look, not another coat of interior sealant. Exterior waterproofing protects your finished spaces, your stored belongings and the foundation itself. Browse our project photos to see the quality of work we deliver across Simcoe County.
What to Expect During the Work
Exterior waterproofing is planned excavation, and we treat your property accordingly. Before digging, we agree on which walls are included, how equipment will access them, how soil will be handled and how decks, walkways, driveways and gardens beside the house may be affected. When the wall is exposed, we inspect it thoroughly; if we find something that changes the scope, such as a damaged footing drain or a larger crack, we explain it and the options before proceeding. Then the membrane, drainage board and new weeping tile go in, we backfill in a controlled way and the surface is graded away from the house. At the end we walk you through each buried layer, so you understand exactly what is protecting your basement.
A Local Note for Midland
Midland’s character is tied to Georgian Bay: the waterfront, the marina and the established residential streets behind downtown. Many homes here are older, with mature trees, settled grading and foundations that have quietly aged. Waterfront and low-lying properties also contend with high water and spring conditions off the bay. The practical sequence is to assess the foundation and grading before investing in basement finishing; fix the outside first, and the inside can be finished with confidence. For seasonal and waterfront homes, we can also talk through scheduling so the work fits the way you use the property.
