The Challenge
A homeowner in San Ramon, CA, was experiencing significant structural concerns, including visible cracks in their walls and ceiling and widening gaps in their hardwood flooring. These signs indicated potential foundation settlement. In addition, the concrete patio outside the home was damaged, requiring repair and sealing. The homeowner sought Foundation Repair of CA to address these issues and restore stability to their home.

Inspection and Diagnosis
Upon inspection, the Foundation Repair of CA team confirmed that the foundation settlement had caused the visible damage inside the home. To address the gaps in the hardwood flooring, cracks in the walls and ceiling, and uneven exterior concrete, a comprehensive repair solution was required to stabilize the foundation and repair the outdoor patio.

Push Pier Installation
The team installed Push Piers using low-profile galvanized brackets to stabilize the home’s foundation. Excavation was completed up to 3 feet, with an 80-foot pier depth clause to ensure the piers reached load-bearing soil. The piers were strategically placed to support the foundation and prevent further settlement. Additionally, the homeowner was offered an annual Care Club Membership, which includes an annual floor elevation survey and evaluation of any cracks, sagging floors, or sticking doors and windows.
Concrete Removal and Replacement
To complete the Push Pier installation, sections of concrete (approximately 2’ x 2’ per pier) were removed and replaced. This necessary step ensured the foundation piers could be installed effectively while minimizing disruption to the concrete surfaces.
NexusPro Crack Repair
Cracks in the patio were addressed by grinding out and cleaning the cracks, then injecting silicone-based NexusPro Crack Repair sealant. This was smoothed and finished with sand to blend seamlessly with the surrounding concrete, ensuring a durable and long-lasting repair.
NexusPro Joint Sealant
To further protect the concrete, NexusPro Joint Sealant was applied to any visible joint gaps up to 1 inch wide. This involved cleaning the joint, inserting a backer rod (if necessary), and injecting silicone sealant for a flexible, water-resistant finish. The joint was smoothed and sanded to improve both appearance and durability.
PolyLevel Injection
To lift and level sunken areas of the concrete patio, the team used PolyLevel, a polyurethane foam injection system. This involved drilling port holes in a grid pattern, injecting the foam underneath the concrete to raise it, and then filling the surface holes to leave the area smooth and stable.

Outcome
Thanks to the comprehensive repair plan executed by Foundation Repair of CA, the homeowner’s foundation is now stabilized, preventing further settlement issues. The interior cracks and gaps in the hardwood floors are no longer worsening, and the outdoor patio has been repaired and sealed for long-term durability. The homeowner now has peace of mind knowing their home is structurally sound and protected against future damage.

This case study showcases the effectiveness of the Push Pier system, NexusPro sealants, and PolyLevel injection in addressing complex foundation and concrete repair challenges.
