Challenge

Problem: A homeowner in Fremont, CA, was experiencing significant sinking and cracking along the walkway that extended from their front door to the driveway. This issue not only caused visible damage to the slab but also created a serious tripping hazard, posing a risk to anyone using the path. The homeowner needed a permanent solution to ensure the walkway was safe and structurally sound again.

Solution

Solution: Foundation Repair of CA provided a lasting solution to address the homeowner's concrete sinking and tripping hazard issues. After a thorough inspection, we recommended and implemented two key systems:

PolyLevel (Foam Injection): To lift the sunken sections of the walkway and stabilize the concrete, we installed PolyLevel, a high-density polyurethane foam. Our team drilled small port holes in a grid fashion across the affected concrete area and injected the foam beneath the surface. As the foam expanded, it raised the sunken concrete back to its original level, restoring the walkway's evenness. We filled the surface holes post-injection to complete the process. This non-invasive solution was perfect for providing long-lasting support without the need for major demolition or replacement.

NexusPro (Joint Sealant): To prevent water from seeping into the concrete joints and causing further erosion or shifting, we installed NexusPro joint sealant. This silicone-based sealant was applied by first cleaning the existing joints, placing a backer rod in any gaps, and then injecting the NexusPro into the joint areas. We finished by smoothing the surface and applying sand as specified in the job drawing. This step ensures the joints remain flexible and water-resistant while maintaining a durable bond.

Outcome: Thanks to the PolyLevel injection, the homeowner's walkway was lifted back to its proper level, eliminating the tripping hazard and restoring safety to their property. The NexusPro joint sealant provided added protection by sealing the joints to prevent future cracking or water damage. The homeowner was pleased with the efficiency of the installation and the long-term stability these solutions provided.

With Foundation Repair of CA’s innovative approach, the homeowner can now enjoy peace of mind, knowing their walkway is both safe and structurally sound for years to come.
