What makes the PolyRenewal™ system different?

Bay Area Underpinning’s PolyRenewal™ system is a two-part polyurethane foam that weighs significantly less than traditional repair materials, yet it will not wash out or erode from under the concrete. Our system does not leach chemicals into the soil. It is a quick-curing solution superior to traditional methods like mudjacking. Learn more during a free inspection with one of our professionals.
