FAQ

Frequently Asked Questions
About Foundation Repair & Drainage

In Portland’s wet climate, expanding soil and hydrostatic pressure push against concrete. Without proper drainage, this stress creates cracks and leaks over time

Exactly. We repair cracks and supports, then design drainage that prevents future problems — not just patch what’s visible.

If leaks or dampness persist, we may recommend additional waterproofing or vapor barriers to ensure full protection.

We don’t just patch cracks — we address the root cause. Every system is engineered for long-term stability and year-round protection from Portland’s rain.

Yes. A well-designed drainage system — like French drains and sump pumps — relieves water pressure and keeps the soil stable around your foundation.
