Driveway sinking or settling — Zaandam, Noord-Holland

When a concrete or asphalt driveway develops uneven sections, sunken slabs, or noticeable dips near the garage, the underlying soil has likely eroded or compacted unevenly. Settling creates trip hazards, pools standing water that accelerates damage, and can redirect runoff toward your foundation. Mild settling (under 1 inch) can often be fixed with mudjacking or polyurethane foam injection — a process that lifts the slab back to grade by pumping material under it through small holes. Severe settling or heaving may require slab removal and re-pouring. A handyman or concrete contractor can assess whether leveling, patching, or replacement is the right call.
