Foundation Crack Injection in Chilliwack, BC

Horizontal cracks are always serious — they indicate lateral soil pressure and potential wall bowing. Vertical cracks wider than 3 mm or actively growing need repair. Hairline vertical cracks under 2 mm with no moisture can typically be monitored. When in doubt, call us for a free on-site assessment.

Interior crack injection typically runs $600–$1,500 per crack depending on method (polyurethane for active leaks, epoxy for structural bonding). If exterior work is required, costs range from $3,000–$5,500 per crack. A full interior perimeter drain (weeping tile) system runs $5,000–$15,000. We provide written quotes with no obligation.

Fraser Valley's clay-heavy soils expand when saturated and contract during dry summers, creating cyclic pressure on foundation walls. Hard frosts from October through March cause water already inside cracks to freeze and expand, widening them each year. Settlement of backfill soil is also common in newer builds in Sardis and Promontory Heights.

Polyurethane is flexible and expands to seal water — the right choice for wet or actively leaking cracks. Epoxy is rigid and bonds concrete back together — used for dry structural cracks where strength restoration matters. Choosing the wrong material is the most common reason DIY repairs fail within a year.

Most interior injections take 2–4 hours for 1–3 cracks. No curing wait — you can use your basement the same day. More extensive work like a full perimeter drain system typically takes 1–2 days.

Generally no. Insurance covers sudden accidental damage (burst pipe, earthquake); gradual soil movement and concrete aging are maintenance items. Some policies cover resulting water damage from a covered event. We provide a detailed written scope of work to support any insurance inquiry.
