Wet winters, poor drainage and loose fill soils cause most residential driveway settlement in the Pacific Northwest. Here's how to spot the cause — and whether lifting is right for your slab.
Most sinking driveways in Spokane share three culprits: water, soil and time. When the ground beneath a slab loses volume — from erosion, from decomposing organic material left during construction, or from soil compaction — the slab loses support and begins to drop. For a broader look at the local soil and climate factors at play, see why concrete sinks in Spokane.
The good news is that in the vast majority of residential driveways, the concrete itself is still structurally sound. The problem is underneath. That's exactly the situation driveway leveling is designed for: instead of demolishing a perfectly usable slab, a specialty concrete leveling contractor fills the void beneath it and raises the slab back to grade. Roof runoff is a common trigger — our guide to downspouts and slab settlement explains why.
Not every slab qualifies. Deeply cracked, spalled or crumbling concrete is usually a replacement job. But a slab that has settled evenly, or tilted at one edge, with only hairline cracks along control joints, is almost always a candidate for lifting. Homeowners across Spokane and the surrounding communities we serve can request a free on-site assessment to confirm whether their driveway qualifies.
