Basement Waterproofing

When water shows up inside—on walls, floors, or at the cove joint—an interior system is often the fastest, least invasive fix. We start with moisture mapping and a foundation assessment to locate the true entry points, then recommend the right combination of: • Interior drainage channel along the footing to capture seepage before it reaches your floor • Sump basin & pump with check valve and optional battery backup (critical in Ottawa power outages) • Vapour barrier & wall encapsulation to separate living space from damp foundation walls • Dehumidification & air quality improvements to control mould risk and odour When to choose interior waterproofing: repeating leaks after heavy rain, hydrostatic pressure under the slab, finished basements you want to protect without excavating outdoors. Benefits: quick install (often 1–2 days), minimal exterior disruption, excellent value. Add-ons: high-water alarm, back-up pump, discharge freeze protection for Ottawa winters.

Foundation Repair

Exterior systems stop water at the source—outside the wall—ideal when you have persistent wall seepage, aging or failed exterior membranes, or poor grading and drainage. Our exterior process: Excavate to the footing with shoring and utility locates for safety. Clean & inspect the wall for cracks, tie-rod holes, honeycombing. Repair cracks with epoxy/urethane injection as needed. Apply elastomeric membrane (spray- or brush-applied) for a seamless waterproof layer. Install drainage board (dimpled membrane) to protect the coating and channel water downward. Replace/upgrade footing drains (weeping tile) with filter fabric and washed stone. Regrade soil & add downspout extensions to move surface water away. Why it matters in Ottawa: freeze-thaw movement and saturated clay put stress on exterior coatings and drains. A modern membrane plus new weeping tile prevents water from ever touching your basement wall. Typical use cases: severe exterior seepage, visible foundation damp spots, landscaping or driveway projects where excavation access is available.
