Sinking concrete slab — Leiden, Zuid-Holland
A concrete slab that has sunk or settled unevenly creates trip hazards, pools water against the foundation, and worsens as the void beneath the slab grows. Causes include soil erosion from poor drainage, tree-root decay leaving voids, or inadequate compaction during the original pour. A concrete mason can lift the slab back to grade using polyurethane foam injection or mudjacking, fill the void, and level the joints so the surface is flush, safe, and drains correctly.
