Watched a 30 year old slab in Tulsa go from spider cracked to looking new after one overlay job
Honestly I helped my uncle prep a driveway slab off Sheridan last weekend that had cracks running every which way for the last 20 years, and I figured we were just slapping lipstick on a pig. Ngl after they ground it down about a quarter inch and rolled on that thin polymer overlay, the thing looked like it got poured yesterday. Made me realize half the "worn out" concrete I've written off over the years just needed the top layer fixed, not a full tear out. Any of you guys been doing overlay work more than repours lately? Curious how they're holding up after a few winters.

That thin overlay is doing what, an eighth of an inch of material over cracks that already moved once? Give it two or three hard freezes and that same crack is gonna ghost right back up through it, just in a straighter line. Grinding a quarter inch off the top also takes away the only part of the slab that was still sound in spots, so now you got a thin skin sitting on busted base. I have seen guys in Oklahoma pull this trick and it looks great for a year, then the edges start curling and popping off in sheets after the second winter. A repour is money up front but at least you are not back out there redoing the whole thing in 2027.
