Foundation Waterproofing in Burlington

Exterior excavation waterproofing for Burlington homes with leaking basements, failed weeping tile, or cracked foundation walls. We do the dig-out properly, not the cheap interior patch.

Why Burlington projects need a tailored approach

Burlington sits on Burlington Bay clay near the lakeshore, Halton Till on the bench above the escarpment, and the homes we work on are spread across neighbourhoods like Aldershot, Tyandaga, Mountainside, Roseland, Shoreacres, Headon Forest, Millcroft, Alton Village and Orchard. North Burlington lots above Mountainside transition to escarpment limestone shelf where rock is often within 600 mm. Lakeshore lots have clay that swells and shrinks seasonally. Combined with Lake-effect milder winter than inland, but escarpment funnels stormwater through Tyandaga and Mountainside in heavy rain, this changes how we design the slab and the base.

We pull permits where needed through City of Burlington Building Department (426 Brant Street), so the work is documented and inspected, not buried under landscaping. Whether you are in postal code area L7L, L7M, L7N, L7P, L7R, L7S, L7T, we serve every Halton Region address with the same crew, the same supervisor, and the same written quote.

How we waterproof a Burlington foundation properly


Our waterproofing process

  1. Step 1. Diagnosis. We locate the leak, check basement humidity, inspect existing weeping tile cleanouts, and confirm whether interior or exterior work is correct for the failure mode.
  2. Step 2. Excavation. Equipment access marked, locates called (Ontario One Call), then careful machine excavation to footing depth with proper shoring.
  3. Step 3. Wall repair and membrane. Cracks repaired, parging where the wall is rough, then primer and rubberized membrane to spec.
  4. Step 4. Drainage and weeping tile. Dimple board fastened, new weeping tile placed in clear stone, filter fabric wrapped, and connected to the sump or gravity outlet.
  5. Step 5. Backfill and grading. Granular backfill compacted in lifts, then topsoil and final grading sloped away from the foundation.
  6. Step 6. Restoration. Walkways, driveway sections, or landscaping disturbed during excavation are restored to original or better condition.
