Concrete Stair Wall Crack Repair in Bonita, CA | PolyLevel & NexusPro

This before-and-after photo set highlights a concrete stair wall crack repair completed by Saber Foundation Repair in Bonita, CA, located in San Diego County. Prior to repair, the concrete showed vertical cracking and separation along the stair wall, a common sign of soil settlement and loss of support beneath exterior concrete structures.

To address the issue, our team used PolyLevel® foam injection to stabilize the underlying soil and support the affected concrete. Once the movement was corrected, the visible cracks and joints were sealed with NexusPro®, a durable, flexible sealant designed to prevent water intrusion and accommodate natural expansion and contraction.

This solution restored stability, improved safety, and significantly enhanced the appearance of the concrete without the need for demolition or replacement. PolyLevel and NexusPro concrete repair offers homeowners in Bonita, San Diego, and surrounding Southern California communities a long-lasting and minimally invasive option for cracked and settling concrete.
