Toronto Basement Waterproofing & Leak Repair
DrainPro designs exterior and interior waterproofing systems that fit Toronto homes—whether it’s a post-war bungalow or a newer subdivision. GTA conditions like freeze–thaw cycles, clay-rich soils, and paved urban lots can push water toward foundations and into cracks, which is why solutions must be correctly specified for each property.
From membranes + dimple board and weeping tile replacement to interior drain channels, crack injection, and sump pumps with battery backup, we stop active leaks and help prevent new ones. Look for signs like water stains, peeling paint, musty odours, or visible mould—all early indicators of a leak that’s worth fixing before it grows.

How We Waterproof Toronto Basements
Assessment → Plan → Install (Exterior or Interior) → Proof & Warranty
Locate & Excavate
Footing Drainage (Weeping Tile)
New perforated weeping tile is set at the footing, wrapped in filter fabric and gravel, and tied to a safe discharge or sump—relieving hydrostatic pressure that forces water through weak points.
We identify where water is entering, then safely excavate along the affected wall down to the footing, keeping the trench neat and protected. Toronto’s freeze-thaw and clay-rich soils can drive leaks, so exposing the problem area lets us treat it properly.
Waterproof the Wall
The foundation is cleaned and primed, then coated with a rubberized waterproofing membrane and covered with dimple drainage board to direct water away from the wall
Backfill, Grade & Verify
We backfill in layers, restore grading away from the house, then perform a function/flow check and review photos with you. Where needed, we recommend a sump pump for extra protection and leave you with our 5-Year Workmanship Warranty.
What Is Basement Waterproofing?
Basement waterproofing stops water from reaching or crossing your foundation. In Toronto, freeze–thaw cycles, clay soil, and heavy summer rain push moisture toward basement walls and the floor-wall seam. We use two main approaches. Exterior waterproofing blocks water on the outside with a rubberized membrane, dimple board, and new weeping tile at the footing. Interior waterproofing manages water from the inside with a perimeter drain channel that leads to a sealed sump pump—great when exterior access is limited. For small, active leaks, crack injection (epoxy/urethane) is a precise fix. Every job is photo-documented and backed by our 5-Year Workmanship Warranty so your basement stays dry year-round.
Common Basement Leak Problems We Fix in Toronto
When to Call the Experts
Waterproofing Problems You Shouldn’t Ignore
If you see damp spots, musty smells, white powder on basement walls, water along the floor–wall seam after Toronto rain, window-well overflow, foundation cracks, or a sump pump that won’t stop, call us.
What doesn’t work
Paint and DIY sealers won’t block outside water. Drain chemicals won’t fix grading or clogged weeping tile. The right repairs are exterior waterproofing (membrane + dimple board), interior drain tile to a sealed sump, crack injection, or weeping tile replacement—we’ll inspect and show photos first.
Preventative Waterproofing Saves You Money
Keep gutters and downspouts clear, make sure soil slopes away, and test your sump (add a battery backup for outages). Book a Waterproofing Inspection for Toronto to get a clear plan and firm price.

Clean sites, photo documentation, and a 5-Year Workmanship Warranty on every job.
