Expert Concrete Repair Company in Richmond, CA

Background
A homeowner in Richmond, CA, noticed that a portion of their concrete patio had begun to sink, creating an uneven surface and potential tripping hazard. Concerned about safety and future settling, they reached out to Foundation Repair of CA for a long-term solution to lift, stabilize, and protect their patio from further settlement.

Assessment
Upon inspection, Foundation Repair of CA’s team identified underlying soil compaction issues that had caused sections of the patio to sink over time. After discussing options, they recommended a combination of PolyLevel Foam Injection for lifting and stabilizing the concrete and NexusPro Joint Sealant to seal the joints and prevent water infiltration that could contribute to further settlement.

Solution

1. PolyLevel (Foam Injection)
The first step was to lift and stabilize the concrete patio using PolyLevel foam injection. Our skilled team drilled port holes in a grid pattern over the affected area to inject the polyurethane foam beneath the patio slab. The expanding foam filled any voids and gently lifted the concrete to restore an even surface. This process is minimally invasive, with the port holes sealed after injection, and it provides lasting support against further settlement.

2. NexusPro Joint Sealant
To protect the patio from water intrusion and potential erosion, our team applied NexusPro Joint Sealant along the patio joints. The process began with thoroughly cleaning the joints, inserting a backer rod to reinforce gaps, and then injecting a durable silicone sealant. The joints were smoothed and finished with sand for a clean look. Although NexusPro does not match the exact color of concrete aggregate finishes, it forms a waterproof, flexible barrier that withstands temperature changes and prevents water from entering under the slab.

Results
The PolyLevel and NexusPro applications effectively restored the homeowner’s patio, eliminating uneven surfaces and safeguarding the structure from further settling. The project met the homeowner's expectations for a reliable, professional solution to their sinking concrete, ensuring the patio remains safe and stable for years to come.

The homeowner called us because he was fed up with walking on his sagging floor. He had decided to inspect what was going on beneath his floor by himself. Upon inspection, he had seen 9 posts that looked like they needed to be fixed. When our Structural Consultant, Mike A. came to the scene, he determined that we could lift and stabilize the floor without removing any of the old posts, but rather by installing our SmartJack Adjustable Post system in near the 9 posts that the homeowner had an issue with. 

Our crew came to the scene and installed 9 SmartJacks, each with a new concrete cast-in-place footing (poured on site). We were able to fix the sagging and give the homeowner peace of mind.
