Local context
Exterior Waterproofing for Mississauga homes
Detached homes across Lorne Park, Mineola, Erin Mills, and Meadowvale often have the side and rear access that exterior waterproofing needs. Where that access exists, treating the outside face of the foundation deals with water before it ever touches the interior.
It is the more involved option, and it is the right one when the wall itself is saturating, when original weeping tile has failed, or when the homeowner wants the foundation itself protected rather than drained.
- Stops water before it reaches the wall
- Addresses failed original weeping tile
- Protects the foundation material itself
Signs this service may be needed
- The exterior wall stays dark and damp well after rainfall
- Soil settles into a trench line along the foundation
- Water enters at several points along the same wall
- Interior repairs have been done before and water returned
- Below-grade block or parging is deteriorating
Common causes of the problem
- Original weeping tile silted up or collapsed
- No membrane or a deteriorated damp-proof coating
- Backfill that traps water against the wall
- Downspouts and sump discharge released too close to the house
- Negative grading created by settled soil or new landscaping
What the work involves
How exterior waterproofing is carried out
Exterior work means excavating down to the footing along the affected wall, cleaning and inspecting the foundation, repairing cracks from the outside, then applying a waterproof membrane and a dimpled drainage board that channels water down to the footing drain.
New or cleared weeping tile in clean stone with filter fabric carries that water away, and the backfill and final grade are set to shed water rather than hold it.
