Soil erosion and settlement often cause concrete slabs in patios, sidewalks and driveways to sink into the ground. This type of settlement isn’t just unsightly; it can also cause more damage and can be a safety hazard. Water tends to pool on sunken surfaces and unleveled floors cause a trip hazard.
Until now, the only solution available to repair sinking slabs was mudjacking, a process that involves drilling holes in the slab to inject a mixture of cement and mud underneath, to raise it back to level.
