Challenge

Overview: A homeowner in Danville, CA, reached out to Foundation Repair of CA after noticing that the sinking and cracking in their walkway and driveway were worsening. Having lived with the issue for a while, they recognized that delaying repairs could lead to more extensive and expensive solutions. Foundation Repair of CA offered a comprehensive approach to address the sinking and cracking issues and restore stability to the home’s concrete surfaces.

Problem: The homeowner’s driveway and walkway were experiencing visible signs of settling, including cracked and uneven surfaces. As these issues progressed, they created tripping hazards and aesthetic concerns. Without intervention, the structural integrity of these areas could degrade further, requiring more costly repairs in the future.

Solution

Solution Provided by Foundation Repair of CA:

PolyLevel (Foam Injection): To address the underlying settling issues, Foundation Repair of CA implemented PolyLevel foam injection. The process began with drilling port holes in a grid pattern to access void spaces beneath the concrete. The team then injected polyurethane foam under the concrete slabs, filling the voids and stabilizing the area. This injection was carefully controlled to lift the slabs back to a more level position, restoring an even and safe walking surface. Afterward, the drilled holes were patched to ensure a smooth finish.
NexusPro Joint Sealant: To prevent future water intrusion and potential further settling, NexusPro joint sealant was applied to the joints between concrete sections. The process included cleaning the joints, placing a backer rod inside the gaps, and injecting NexusPro silicone sealant. The sealant was then smoothed and finished with sand to match the aesthetic requirements as closely as possible. While NexusPro does not fully replicate the existing concrete finish, it provides a durable and flexible seal that can accommodate slight movements in the concrete, extending the life of the repair.
NexusPro Crack Repair: Foundation Repair of CA used NexusPro Crack Repair to treat the visible cracks in the walkway and driveway. This involved grinding out and thoroughly cleaning each crack before injecting the silicone sealant. Once injected, the sealant was smoothed and finished with sand for a consistent appearance. The durable NexusPro sealant is designed to move with the concrete, helping to prevent future cracking in the treated areas.

Outcome: Upon completion of the project, the homeowner’s driveway and walkway were stable, level, and free from hazardous cracks and uneven sections. Foundation Repair of CA's use of PolyLevel and NexusPro systems provided a durable, aesthetically pleasing solution that will prevent further deterioration and protect the homeowner’s investment for years to come. The homeowner was pleased to have a restored and safer walkway and driveway, knowing that their decision to address the issues now helped them avoid more severe problems and higher costs down the line.

Conclusion: This Danville project highlights the effectiveness of PolyLevel and NexusPro solutions in stabilizing and sealing concrete surfaces. By addressing both structural and surface-level issues, Foundation Repair of CA provided the homeowner with a lasting solution that met both their safety and aesthetic needs, reinforcing our commitment to delivering high-quality foundation and concrete repair services throughout California.
