Concrete Stair & Walkway Repair in Bonita, CA | PolyLevel & NexusPro

This before-and-after photo set shows a concrete stair and walkway repair completed in Bonita, CA, a suburb of San Diego, by Saber Foundation Repair. The original issue included a visible crack and separation where the concrete steps met the adjacent structure, a common problem caused by soil settlement and movement beneath exterior concrete in coastal Southern California.

To correct the problem, our team stabilized and lifted the affected concrete using PolyLevel®, a high-density polyurethane foam designed to fill voids and restore proper support beneath the slab. Once the concrete was stabilized, the crack and joint were sealed with NexusPro®, a flexible, waterproof sealant that helps prevent moisture intrusion and future deterioration.

This repair restored structural integrity, improved safety, and enhanced the appearance of the concrete without the need for removal or replacement. Concrete lifting and crack repair using PolyLevel and NexusPro is an effective, long-lasting solution for homeowners in Bonita, San Diego County, and surrounding Southern California communities dealing with cracked or settling concrete.
