Concrete driveway heaving and uneven — Den Haag, Zuid-Holland
Concrete driveway slabs that lift, tilt, or become uneven are usually caused by frost heave (water in the sub-base freezing and expanding), tree root growth underneath, or poor compaction of the gravel base during original installation. The resulting trip hazards and pooling water worsen every freeze-thaw season. A concrete mason can mudjack (pump a cement slurry under the slab to lift it back to grade) for $500–$1,500 per slab, use polyurethane foam injection ($1,000–$3,000) for a lighter, longer-lasting lift, or remove and re-pour the affected section ($8–$15 per square foot). If root intrusion is the cause, the roots need to be addressed first or the heaving will recur.
