Uneven concrete walkway — Hilversum, Noord-Holland

Sunken or heaved concrete walkway slabs create trip hazards, collect standing water, and reduce curb appeal. The problem is typically caused by soil erosion, tree root growth, or freeze-thaw cycles that shift the sub-base. A concrete mason can level the slabs through mudjacking or polyurethane foam lifting, or replace severely damaged sections with new concrete or pavers.
