Basement Flood Protection Built for Real Toronto Conditions
Basement flooding doesn’t happen by accident.
It happens when groundwater pressure has nowhere to go.
A professionally installed sump pump system protects your home by collecting excess groundwater and safely removing it before it enters your basement.
At Kome Waterproofing and Underpinning Inc, we install custom sump pump systems designed specifically for Toronto & GTA homes — based on soil conditions, foundation type, and real-world water issues.

What Is a Sump Pump — and Why Toronto Homes Need One
A sump pump is installed in a sump pit below your basement floor.
As groundwater rises, it flows into the pit and is pumped away from your foundation through a discharge line.
In Toronto & GTA, sump pumps are essential because of:
-
Heavy rainfall and extreme storms
-
Aging weeping tile systems
-
High water tables
-
Older foundations not built for modern water volumes
Without a sump pump, water pressure builds until it finds a weak point — cracks, joints, cold joints, or floor drains
-
