The causes of concrete settlement and sinking are the same whether it's a driveway, walkway, patio, garage floor, or pool deck. As soil underneath a concrete slab shrinks, settles or washes away, this leaves empty space, or voids, beneath the slab. With the soil no longer supporting the slab, the concrete will sink, creating an uneven surface.
If your concrete is structurally-sound, why replace it? Replacing the concrete won't fix the soil problem that's causing the settlement. Concrete leveling is the answer. Contact Laumann's Outdoors today for an on-site inspection and free cost estimate in the Wright County, Minnesota area.
