Why Foundation Cracks Leak

Most foundation cracks develop from settlement, hydrostatic pressure, or thermal expansion. McMinnville's clay soil expands when wet and contracts when dry, which puts stress on concrete walls. Over time, small cracks widen and allow water to seep through during heavy rain. Once water finds a path inside, it follows the crack and drips onto your basement floor or runs down the wall. Some cracks are structural and require engineering evaluation, but most are minor and can be sealed effectively.

Immediate Steps After Water Enters

Remove standing water using a wet vacuum or sump pump. Move anything valuable away from the leak and place a bucket or tarp under the drip to contain water. Do not attempt to seal the crack from the inside while water is actively leaking. The pressure will push through the sealant and it will fail. Instead, wait for dry weather and have the crack professionally evaluated and sealed from the exterior if possible.

Professional Foundation Crack Repair and Waterproofing

We inspect the crack to determine if it's structural or cosmetic, then recommend the appropriate repair method. For minor cracks, we inject polyurethane or epoxy from the inside to create a watertight seal. For larger or active cracks, we excavate the exterior, apply waterproof membrane, and install drainage to relieve hydrostatic pressure. If water has already caused interior damage, we extract it, dry affected materials, and remove mold if present. Once the foundation is sealed and the interior is dry, we monitor the area during the next rain to verify the repair is holding.

Insurance Coverage for Foundation Leaks

Foundation cracks from settlement or soil movement are usually excluded as maintenance issues. However, water damage that results from a sudden crack may be covered. We document the timeline, photograph the crack and interior damage, and provide a scope that explains whether the leak was gradual or sudden. If any portion of the loss is covered, we handle that part of the claim.

If water is leaking through your foundation, call for a free inspection. We'll assess the crack, recommend the right repair, and dry your home before mold starts growing.
