Restoring Stability to a Slab Foundation in Fresno, CA

Tuesday, February 11th, 2025 by Mike Gray

Challenge

Project Overview

A homeowner in Fresno, CA, faced a challenging issue with their home: settlement beneath the slab foundation had caused cracking throughout a section of the slab. Concerned about the structural integrity of their home and the potential for further damage, the homeowner contacted Foundation Repair of CA for an expert assessment and solution.

The Problem

The homeowner observed visible cracking in the slab foundation and was worried about its progression and the underlying issues causing it. Settlement beneath the slab, often caused by shifting soil or uneven load distribution, was identified as the root cause. Left unaddressed, this type of damage could worsen, leading to additional cracks, uneven flooring, and even structural instability.

Solution

Assessment & Proposed Solution

Foundation Repair of CA conducted a thorough evaluation of the property and determined that the foundation settlement required a multi-step solution to stabilize the slab, prevent further movement, and repair the existing damage.

The team recommended the following steps:

X-Ray Slab Scanning

To ensure precision during the repair process, an X-ray machine was used to detect rebar and post-tension cables embedded in the slab. This process minimized the risk of damaging these critical components during drilling or cutting.

PolyLevel Foam Injection

The PolyLevel foam injection system was used to stabilize the slab and lift it back into place.
This process involved drilling small port holes in a grid pattern across the affected area and injecting expanding polyurethane foam beneath the slab. The foam filled voids, reinforced the soil, and raised the slab to its original elevation. Surface holes were filled upon completion.

Slab Crack Repair with SealBoss

The existing cracks in the slab were prepared for repair by grinding them with a V-notched blade to increase the surface area for bonding.
SealBoss polymer was applied to seal the cracks. Once cured, the repaired areas were smoothed to align with the existing slab surface. While this method restored the slab’s functionality, it was noted that the repair areas would not match the original concrete's color or finish.

Execution

The repair process was carried out efficiently, with a focus on precision and minimizing disruption. The X-ray scanning process guided the installation team, allowing them to avoid critical reinforcements during slab drilling. The PolyLevel foam injection process successfully stabilized the slab, halting further settlement and restoring the foundation's integrity. Finally, the cracks were repaired with SealBoss polymer, ensuring a durable and long-lasting seal.

Outcome

The homeowner was relieved to see their foundation stabilized and the cracks sealed. By addressing both the root cause of the settlement and the visible damage, Foundation Repair of CA delivered a comprehensive solution that restored the home's structural integrity.

Key Benefits

Stability Restored: PolyLevel foam injection effectively halted further settlement.
Cracks Sealed: SealBoss polymer repair provided a durable and long-lasting solution to visible cracks.
Minimized Risk: X-ray scanning reduced the chance of damaging critical slab components during repairs.

The homeowner expressed their gratitude for the team's professionalism, clear communication, and thorough execution of the project.
