Vaughan Basement Waterproofing and Leak Repair
Clay holds water near the wall and driveways often sit higher than the basement floor. Older properties may have clay weepers that are clogged or broken. Newer blocks can settle and push water to the footing. We start with a camera and moisture check. Then we install the right repair. Exterior membrane with dimple board and a new footing drain. Or an interior drain to a sealed sump with optional battery backup. We also do epoxy or urethane crack injection and backwater valves for storm surges.
Early signs in Vaughan include white salt on block walls, a damp line where the floor meets the wall after rain, water in window wells, and a pump that runs for hours.

How We Waterproof Vaughan Basements
Inspect then plan then install exterior or interior then photo proof then 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
Waterproofing keeps ground water from crossing your foundation. In Vaughan, clay soils and storm run off raise pressure at the footing. We use two main methods. Exterior waterproofing adds a rubber membrane, dimple board, and new weeping tile to move water away before it reaches the wall. Interior waterproofing collects water inside with a perimeter drain and sends it to a sealed sump pump. This helps when side yards are tight or you want to keep patios and walkways in place. For single leaks we use crack injection with epoxy or urethane. Every job includes photo proof and a 5 Year Workmanship Warranty.

When to Call the Experts
After a driveway or patio project
If new concrete or stone now sits higher than the basement floor, water can push toward the wall. Watch for a wet line at the floor joint or soft baseboards. Call for an inspection before the next storm.
Cold room and fruit cellar leaks
Front cold rooms sit under porches and often leak at the slab edge. Signs include damp corners, peeling paint, or a musty smell in that room only. We seal the joint and add drainage so it stays dry.
Ravine and slope pressure
Homes near valleys or on a hill can see water move toward the footing after long rain. If window wells fill or the sump runs nonstop, we add a well drain, improve grading, and upgrade the weeper or interior drain.
