Seal a leaking or hairline foundation crack from inside, usually in half a day, with no digging.
Poured concrete cracks are sealed by injecting resin under pressure through ports along the crack. Polyurethane foam expands and stays flexible, which suits the wet, moving cracks we see after a spring melt. Epoxy cures rigid and bonds the two sides back together, which suits a dry crack where strength matters.
The crack is cleaned, surface-sealed, ported and injected until resin shows at the next port. The ports come off once it cures. There is no excavation and no mess outside.
Injection works on poured walls. Block and stone foundations, common in older Ottawa homes, need a different fix, usually from the outside.
