Restoring a Backyard Patio in Hayward, CA

Challenge

The Problem
A homeowner in Hayward, CA, noticed their decorative concrete patio in the backyard was sinking and becoming uneven. Over time, soil erosion had washed away the support beneath the concrete, leading to noticeable settlement. The uneven surface posed not only an aesthetic issue but also a potential safety hazard. Concerned about further damage and seeking a long-term solution, the homeowner reached out to Foundation Repair of CA.

The Inspection
The Foundation Repair of CA team conducted a thorough inspection of the patio and identified the extent of the soil erosion and settlement. Their assessment revealed that the soil voids beneath the concrete were the primary cause of the instability. The homeowner wanted to restore the patio to its original level while ensuring it remained stable in the future.

Solution

The Solution
To address the issue, Foundation Repair of CA proposed the installation of PolyLevel, a polyurethane foam injection system known for its durability and effectiveness. This solution would:

• Lift the settled concrete to its original level.
• Fill the voids beneath the patio to restore its stability.
• Provide long-lasting support to prevent future settlement.

Scope of Work
The project involved the following steps:

Drilling Port Holes: The crew drilled small port holes in a grid-like pattern across the affected areas of the concrete patio, as indicated in the job drawings.

Injecting Polyurethane Foam: Using specialized equipment, the team injected PolyLevel foam beneath the concrete. The foam expanded, filling the voids and lifting the patio back to a level position.

Sealing Surface Holes: Once the injection process was complete, the port holes were carefully filled and sealed, leaving the surface clean and restored.

The Outcome
The PolyLevel solution successfully lifted the patio back to its original, even position. The injection process not only restored the patio’s appearance but also provided a stable foundation that will prevent future settling. The homeowner was thrilled with the results, noting that the process was minimally invasive, quick, and left no visible damage to their decorative patio.

Conclusion
Foundation Repair of CA’s expertise and innovative use of PolyLevel foam allowed this Hayward homeowner to reclaim their backyard patio. By addressing the underlying issue of soil erosion and providing a permanent solution, Foundation Repair of CA delivered peace of mind and a beautifully restored outdoor space.
