Dampproofing in Toronto costs $3–$6 per square foot applied to exterior foundation walls — less expensive than waterproofing but only resists moisture, not hydrostatic water pressure from high water tables.
Protect your foundation from moisture vapor and capillary water with professional moisture control. Required by NBC 9.13.2 for all below-grade construction, moisture control is your first line of defense against moisture infiltration, mold growth, and structural deterioration.
Note: Dampproofing controls moisture vapor and capillary action but does NOT resist hydrostatic pressure. Waterproofing required where water table creates pressure against foundation.
Rain and snowmelt flowing toward foundation
Control: Grading, eavestroughs, downspouts

Critical: Dampproofing cannot bridge gaps or pores. Proper surface preparation determines system effectiveness and longevity.
Exception: No dampproofing required for garage floors or if installed over 100mm+ of coarse clean granular fill (max 10% passing 4mm sieve).
