Concrete Overlays & Resurfacing in Lawrence, KS

It depends on whether the surface is worn or the base is fatigued. Years of commuter and game-day load wear the top face of a Lawrence lot long before the slab fails, and a worn surface over a sound base is exactly what a bonded overlay is for. A fatigue-cracked base is different, and no topping fixes it.

So the read starts with the cracks, not a sales quote. We separate surface wear from a base that has flexed itself apart, then tell you which one you have before anyone talks about resurfacing.

Where the base is sound, a bonded overlay rebuilds the load-carrying surface the traffic wore away. The topping has to be placed at its rated minimum thickness — thin enough to tie in flush at edges and doorways, thick enough to carry the load without curling or breaking up under the next event surge. Too thin and it ravels off; too thick at an edge and it lips.

On high-cycle commuter lanes that thickness discipline is the whole game. We spec the overlay to the actual traffic a Lawrence lot sees rather than a one-size number, so a resurfaced 23rd Street lot holds through the load it was rebuilt for.

Lawrence straddles two river valleys. Slabs in the Kansas River bottoms and the Wakarusa lowlands sit on alluvial ground with a high water table, and concrete heaves and settles there where the uplands stay put. That movement drives cracks straight up through a new topping — reflective cracking — unless the joints are honored, so we saw the overlay over every existing joint.

On grade-level slabs near the river we also test the moisture vapor drive before resurfacing. A damp valley slab poured without a barrier pushes vapor up through the concrete and releases the topping regardless of how clean the prep was. We read the water first so the overlay stays down.

Resurfacing prices off the prep, the thickness, and the drainage — not the square footage. A sound slab with a straight wear course is inexpensive per foot; a valley lot needing joint honoring, vapor testing, and a load-rated thickness costs more but stays well under full replacement. The honest line holds: a fatigue-cracked base gets reconstructed, because a topping fails with it. Our replacement page covers that call, and the cost guide covers how we price.

You get a written number after we sound the slab, read the joints, and check the drainage in person. Commercial permits run through the City of Lawrence and Douglas County under KDHE standards — see our permits guide.
