Combining Concrete Overlays and PVA Fibers to Fix Cracking

Jerry Van Cleave of VanCrete Decorative Concrete repaired this Tulsa, Okla., driveway using a ductile concrete mix with PVA fibers from GST International LLC.

Besides being used to make thin yet durable countertops that don’t easily chip or break, a mix of PVA fibers and ductile concrete does an excellent job of fixing cracks in concrete. Jerry Van Cleave, co-owner and president of VanCrete Decorative Concrete in Tulsa, Okla., who has been using GST’s ductile cement mix for the past two to three years as a repair product, sings its praises.

“I tried epoxy and urethane injection, but they didn’t work as patches to keep the cracks from reappearing under an overlay,” he says. He began to work with Jim Glessner of GST International LLC, and after much testing, concluded that ductile concrete mixed with PVA fibers was the way to go.

To work well, he continues, a heavy coat is required to gain adhesion. “I mainly use it for difficult repairs where cracks are excessive or there is a heavy fracture. In the past, I had to cut out those sections and repour. But I don’t have to do that now. I’ve had good success with the ductile cement product. I haven’t had any callbacks.”
