Know What You Have
Types of Foundation Damage in Chilliwack
The crack type tells you the cause. The cause tells you the fix. Here is what we see most often in Chilliwack homes and what each one means.
Vertical Cracks
Run straight up and down the wall. Usually from concrete shrinkage during the original cure or minor settlement over time. Most vertical cracks under 6 mm with no active moisture are not structural. Polyurethane or epoxy injection stops the water and seals the crack.
Horizontal Cracks
Run side to side across the wall. This is the crack that gets our full attention. Horizontal cracks mean lateral soil pressure is pushing against the foundation. Fraser Valley clay expands significantly when saturated. Left alone, the wall can bow inward. Carbon fibre straps or wall anchors stop the movement.
Diagonal and Corner Cracks
Run at an angle, often from window or door corners. Typically caused by differential settlement where one section of the footing moves more than another. Common in homes built on filled ground, which includes parts of Sardis and Promontory Heights. Severity depends on width and whether they are growing.
Stair-Step Cracks
Follow the mortar joints in a stair-step pattern. Found in older block or brick foundations, which are common in downtown Chilliwack homes built before the 1980s. Usually caused by frost heave or settlement. The mortar fails before the block does. Repair involves repointing and in some cases carbon fibre reinforcement.
Bowing or Leaning Walls
The wall has moved inward at the middle. This is active structural movement, not just a crack. Most common where clay soils have been saturated for extended periods. In the Fraser Valley, that is most winters. Carbon fibre straps can stabilise a wall that has moved less than 2 inches. More movement usually means wall anchors or full excavation.
White Staining (Efflorescence)
White or grey powder on concrete walls. Not a crack you can see, but a sign that water is moving through the wall and depositing minerals on its way. The crack or pore is there even if invisible. Efflorescence that keeps coming back usually means an exterior drainage problem or a crack that needs injection and a waterproof membrane.

What Our Clients Say
Real results from real homeowners across Chilliwack and the surrounding area.
"Found a crack in my foundation wall after last winter. They came out same week, did the polyurethane injection, and explained exactly what caused it — clay soil movement under the slab. Two rainy seasons later, completely dry. Would recommend to anyone in Chilliwack."
"Our crawl space was a disaster — moisture everywhere, joists starting to show mould. They encapsulated the whole thing and installed a vapour barrier in two days. Huge difference in the smell upstairs. Worth every penny."
"Got three quotes. These were the only ones who actually explained the difference between polyurethane and epoxy and why our crack needed waterproofing-grade injection. Honest about what it needed, didn't oversell. Two years on — no issues."
"Old house in downtown Chilliwack, poured concrete walls from the 70s. Had a horizontal crack I was worried about. They used carbon fibre straps to stop it progressing. Told me honestly what it needed rather than upselling me on a full waterproofing job."
"Called for a wet basement — they installed an interior perimeter drain with a sump pump. Done in two days. Basement has been dry through two full BC rainy seasons. Professional crew, clean worksite."
"Noticed white staining on our basement wall after we moved in. They identified it as efflorescence from an invisible hairline crack, injected it, and applied a waterproof membrane. Haven't seen a spot since. Appreciated that they explained what was actually happening rather than just quoting."

FAQ
Frequently Asked Questions
How do I know if my foundation crack is serious?
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.
How much does foundation crack repair cost in Chilliwack?
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.
What causes foundation cracks in the Fraser Valley?
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.
What is the difference between polyurethane and epoxy injection?
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.
How long does a foundation crack injection take?
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.
Is foundation repair covered by home insurance in BC?
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.
