Richmond Hill Basement Waterproofing and Leak Repair
Hills and walkouts can push water to the footing. Older streets may still have clay weepers that are clogged or broken. Newer builds can settle and leave a low spot along the wall. 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 heavy rain.
Early signs in Richmond Hill include white salt on concrete, damp baseboards, water where the floor meets the wall after storms, and a sump that runs for hours.

How We Waterproof Richmond Hill 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 Richmond Hill, clay soil and moraine slopes raise pressure at the footing during storms and thaw. 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 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 finishing the basement
If new drywall, flooring, or a bathroom went in and you notice musty air, soft trim, or a damp line after rain, call for an inspection. We check behind finishes with a camera and moisture meter and give you a clear plan.
Garage and cold room trouble
Water at the side wall near the garage or a damp cold room under the porch is common on sloped lots. Signs include peeling paint, rust at posts, or wet corners in the cold room. We seal joints and add drainage so it stays dry.
Winter discharge problems
If the sump line freezes or dumps water beside the house, it can recycle right back in. We add a proper discharge, check valve, and backup options. We also regrade where needed so water flows away.
