Interior Waterproofing in Etobicoke
Interior waterproofing manages water once it has reached the foundation. Instead of excavating the outside of the house, an interior system collects water at the base of the wall and moves it to a sump pit, where a pump discharges it away from the building.
It is often chosen when exterior access is limited by driveways, decks, additions, neighbouring properties or mature landscaping, which is common on narrow Etobicoke lots.
How an interior drainage system works
A channel is cut into the concrete slab along the interior perimeter of the affected walls. Drainage pipe is bedded in clean stone in that channel, connected to a sump pit, and covered with new concrete. On block foundations, a membrane or drainage board may be run down the wall so water travelling through the block is directed into the pipe rather than out onto the floor.
The sump pit and pump are the working end of the system. Sizing the pit, choosing a pump that suits the volume, and running a discharge line that carries water well away from the foundation all matter as much as the pipe itself.
Problems this service addresses
- Water seeping at the joint where the basement floor meets the wall

- Basements that cannot be excavated because of access restrictions
- Repeated flooding of a finished lower level
Potential benefits

Landscaping, driveways and patios stay in place
Gives the basement a controlled outlet during heavy rain
Can be combined with crack repair and backup pump systems
How the process works
Confirm the water path
We determine whether water is arriving at floor level, through the wall, or from a plumbing source, since interior drainage only helps with the first two.
Plan the run
The affected walls, sump location, discharge route and any mechanical obstructions are mapped out before work starts.
Install the system
Concrete is cut and removed, drainage pipe and stone are set, the sump pit is placed, and the slab is restored.
Test the discharge
The pump and discharge line are run and checked so water is being carried away from the foundation, not back toward it.
Interior Waterproofing in Etobicoke
Many Etobicoke semis and townhomes near Islington, Rexdale and Mimico sit close to property lines, leaving little room for machinery. Interior waterproofing is frequently the practical route on these properties because all the work happens inside the basement.
Homes with finished basements built in the 1980s and 1990s across Central Etobicoke often show water at the floor-wall joint first, which is exactly what an interior perimeter system is designed to capture.
