Basement Waterproofing The Danforth, Toronto

Common basement problems in The Danforth

Homes along The Danforth are typically 90 to over 100 years old. Their foundations are often poured concrete, brick, or a mix of stone and block, and the original waterproofing — if there was any — was a thin asphalt coating that has long since cracked and peeled. With the wall coating gone, groundwater presses directly against the concrete.

The most common basement waterproofing issue we see on The Danforth is a leaking crack in a poured concrete wall. These are usually vertical or diagonal and can be sealed with polyurethane injection from the inside, without touching the outside of the house. That matters on The Danforth, where front yards are small and attached homes make exterior excavation hard.

When water is coming in at the floor/wall joint instead of through a crack, the usual cause is failed weeping tile at the footing. An interior perimeter drainage system tied to a sump pump is often the practical fix. For persistent wall dampness on a detached home, exterior waterproofing stops the water at the wall.
