Fix it before
you replace it.

It depends whether the base failed or only the surface did. Hairline surface cracks and spalling are repairable. If the slab has heaved, settled unevenly, or cracked completely through and shifted, the base underneath has failed and a repair will just crack again.

Crack injection typically runs $8 to $16 per linear foot. A bonded resurfacing topping is roughly $6 to $10 per square foot. Both are far cheaper than replacement – when the slab is a genuine candidate for repair.

Almost always de-icing salt combined with freeze-thaw on concrete that was poured without adequate air entrainment. Water gets into the surface, freezes, expands, and pops the top layer off. A 32 MPa air-entrained pour largely prevents it.

We can address minor differential settling with a bonded topping. True slab-jacking or polyurethane lifting is a specialist trade – if that is what you need we will tell you and point you to someone who does it properly.

A properly bonded repair on a structurally sound slab lasts ten years or more. A repair on a slab whose base has failed will crack again within a couple of seasons, which is exactly why we assess the cause first.
