The Problem

The homeowners noticed persistent dampness along their basement walls and a lingering musty smell, classic signs of drainage failure. Like many older properties in Toronto, this home was originally built with clay weeping tiles. Over decades, these clay pipes had become brittle, clogged with tree roots, and partially collapsed, effectively trapping water against the foundation instead of draining it away. This compromised the home’s basement waterproofing integrity.

Our Professional Assessment

Upon excavation and inspection, we confirmed that the existing drainage system had reached the end of its lifespan. The clay tiles were segmented and blocked, preventing proper water flow. We determined that a spot repair would not suffice; the home required a complete perimeter drain replacement to ensure long-term dryness and structural health.

The Solution We Recommended

We recommended upgrading the entire exterior drainage system to modern PVC (Polyvinyl Chloride) piping. Unlike clay, PVC is continuous, durable, and resistant to root intrusion. This comprehensive drain system replacement would not only resolve the current water ingress but also align the home with modern building standards, similar to recommendations found in the City of Toronto’s Basement Flooding protection guidelines.

The Work Performed

  • Excavation: Carefully dug a trench along the foundation footing to expose the old system.
  • Removal: Removed the damaged and collapsed clay weeping tiles and debris.
  • System Installation: Installed new 4-inch perforated PVC piping with a filter sock to prevent silt clogging.
  • Gravel Bedding: Covered the new pipe with ¾-inch clear gravel to maximize drainage speed.
  • Backfilling: Refilled the trench with native soil, compacting it in layers to prevent future settling.

The Results

  • Dry Basement: The dampness and musty odors were eliminated immediately.
  • Superior Flow: The new PVC system moves water away from the foundation rapidly.
  • Longevity: The homeowners now have a drainage system rated to last 50+ years.
  • Property Protection: Stopped the risk of hydrostatic pressure building up against the walls.
