Crack repair
Seals an isolated crack in poured concrete.
Fits when water tracks down one line in poured concrete and the rest of the wall stays dry.
Wall cracks
Water through a foundation wall crack
Water following a line down a poured concrete wall in a Oakville basement is often coming through that crack. Sealing one isolated crack from inside can be the right repair. If the wall is wet beyond that line, the wall is block or stone, or water shows up only after the ground is saturated, the crack is probably not the whole problem. Someone has to see the wall before a method is chosen.
Possible causes
- An isolated crack in poured concrete
- Hydrostatic pressure after rain or snowmelt
- Wet wall beyond the crack, which points past injection
Repairs that are usually considered
Exterior waterproofing
Stops water at the outside of the wall.
Fits when seepage is wider than the crack, or the wall is block, stone, or saturated soil.
When to call
Flowing water, a sewage smell, or water near outlets or the electrical panel needs same-day help. A damp line that shows up after rain should be looked at before the next storm.
