Exterior Waterproofing in Etobicoke
Exterior waterproofing treats the problem at the source by excavating alongside the foundation, cleaning and repairing the wall, applying a waterproofing membrane, and rebuilding the drainage at the footing.
It is the more involved option, and on the right property it is also the most direct: water is stopped before it can enter the wall assembly at all.
What exterior waterproofing includes
Excavation is carried out down to the footing along the affected wall. The foundation is exposed, cleaned, and any cracks, honeycombing or deteriorated parging are repaired. A waterproofing membrane is applied to the wall, typically followed by a dimpled drainage board that gives water a downward path and protects the membrane during backfill.
New weeping tile is set at the footing in clean stone with filter fabric, and connected to a drainage outlet or sump. Backfill and grading are then rebuilt so surface water is directed away from the house rather than pooling against the new work.
Problems this service addresses
- Water entering through cracks or cold joints in the foundation wall
- Old tar damp-proofing that has degraded or was never applied
- Weeping tile that is collapsed, crushed by roots, or full of silt
- Negative grading that channels rainwater toward the foundation
- Repeated leaks that interior repairs have not resolved

How the process works
Assess and locate services
Access, utility locates, tree roots, hardscaping and the specific wall to be excavated are all reviewed first.
Excavate to the footing
The affected section is dug out so the full height of the foundation wall can be inspected and repaired.
Repair and membrane
Cracks are sealed, the wall is prepared, and membrane plus drainage board are applied from footing to grade.
Drainage and backfill
New weeping tile in stone is installed, the trench is backfilled, and grading is restored to slope away from the house.
Exterior Waterproofing in Etobicoke
Detached homes in The Kingsway, Humber Bay and parts of North Etobicoke often have side and rear yards with enough clearance for excavation equipment, which makes exterior work feasible where a semi-detached property may not allow it.
In older Etobicoke neighbourhoods, exterior work also gives an opportunity to replace clay or early plastic weeping tile that has silted up over the years.
