Concrete Repair in Lenexa, KS

Concrete repair in Lenexa depends on which era your slab comes from. Old Town concrete is often decades old and brittle, near the end of its service life; City Center and the newer K-10 developments sit on fill that is still settling. We identify which before quoting, because a worn slab and a sinking one need different fixes entirely.

Getting that read right is the whole job. We sound the concrete for the hollow ring of delamination, classify every crack, and probe the edges for voids. If yours is an old slab that has simply run out of life, we say so and point you to full replacement rather than selling patches that fail by spring.

An older Lenexa slab gets repaired only where it can bond to sound concrete. We saw a clean perimeter around the damage, remove material to sound substrate, and abrade it to an ICRI CSP profile so the new concrete keys in. The weak laitance layer comes off, the surface reaches saturated surface-dry, and we place at 4,000 PSI.

We never feather-edge a patch to a thin, unsupported border — that always breaks off, the reason so many old-slab repairs look worse a year later. Full-depth breaks get load transfer restored across the joint so the panels move together instead of apart.

Freeze-thaw cycling shows first as scaling — the top surface flaking away — then spalling at joints and edges where deicing salt collected. Once water reaches the reinforcement, corrosion starts and the expanding rust breaks the slab from inside.

Shallow scaling on a sound slab takes a bonded resurfacing overlay. Spalling with exposed reinforcement means removing concrete to sound material behind the steel, cleaning the corrosion, and rebuilding — there is no patch over rusting rebar that holds.
