Exterior Waterproofing in North York

Project Overview.

A North York homeowner reached out to Aquatech after noticing signs of water infiltration around their foundation, putting the basement at risk of moisture damage, mold growth, and structural issues. To protect the home long-term, they chose a full exterior waterproofing solution – excavating around the foundation, repairing any defects, and applying a high-quality waterproof membrane to keep the basement dry for years to come.

Challenges:

  • Water Infiltration at the Foundation: Moisture was penetrating the foundation walls, putting the basement at risk of ongoing water damage.
  • Undetected Foundation Defects: Hidden cracks and defects needed to be exposed through excavation before any waterproofing could begin.
  • Aging Waterproofing Protection: The original exterior coating was no longer providing a reliable barrier against groundwater.
  • Risk of Mold and Structural Damage: Left untreated, the ongoing moisture exposure threatened both the home’s structural integrity and indoor air quality.

Materials Used

  • Aqua Bloc 770-06 waterproof membrane
  • Yellow Jacket fibre mesh reinforcement
  • Hydraulic cement for crack sealing
  • 4″ x 100′ corrugated drain pipe with filter sock
  • Termination bar for membrane edge sealing

Solutions Implemented:

  1. Foundation Excavation: Excavated around the foundation to expose the walls and identify any cracks or structural defects.
  2. Defect Repair: Repaired all identified cracks and defects to restore the foundation’s structural integrity.
  3. Waterproof Membrane Application: Applied a high-quality waterproof membrane and coating to the exterior foundation walls, creating a durable barrier against moisture.
  4. Weeping Tile Installation: Installed new corrugated drain pipe to carry groundwater safely away from the foundation.
  5. Backfilling and Site Restoration: Backfilled around the foundation and restored the property to its original condition, on time and within budget.
