Case Study: Foundation Stabilization for Layne Construction Office, Chandler, AZ
Commercial Foundation Repair Using Deep Soil Injection and Structural Polymer
Background
The regional office for Layne Construction in Chandler, Arizona, was facing serious foundation settlement. The issue caused visible damage to interior office spaces and the exterior brick walls. The company needed a long-term solution to protect the structure’s stability and prevent further deterioration.
Problem & Analysis
Soil testing was carried out by project engineers, and additional testing using a dynamic cone penetrometer (DCP) confirmed the problem: layers of weak, poorly compacted soil existed between 5 and 12 feet below the foundation. These unstable layers were the cause of the settlement and structural distress.
Poor soil compaction can occur during original site development or over time due to water infiltration, drought cycles, or nearby construction. When the ground beneath a building loses density, it becomes unable to support the structure’s weight, leading to cracking, uneven floors, and even long-term damage.
In commercial buildings like this one, early signs of foundation settlement often go unnoticed until visible damage appears. That’s why proper soil analysis is critical for diagnosing the root cause and choosing a permanent solution.
Solution & Installation
StrataLock worked in collaboration with project engineers to create a focused plan targeting the unstable soil. Our team used a deep soil injection process, installing injection tubes along the affected perimeter at varying depths.
We then injected our specially formulated geotechnical polyurethane, which expanded underground to fill hidden voids, compress loose soil, and lift the settled foundation. This structural repair method improved the load-bearing capacity of the soil and reduced the risk of future movement.
StrataLock Deep Soil Injection
At StrataLock, we use deep soil injection as a proven method for stabilizing weak soils beneath structures without the need for excavation. This process involves injecting a high-density, expanding structural polymer into the soil at targeted depths.
As the geotechnical polyurethane expands, it fills hidden voids and compresses surrounding soil layers. This strengthens the ground beneath buildings, roads, or commercial facilities and improves the load-bearing capacity of the foundation.
Our process is precise, fast, and minimally disruptive—making it ideal for commercial projects like Layne Construction’s office, where ongoing operations must continue uninterrupted.
Results
The repair process was completed with minimal disruption to office operations. The building was successfully stabilized, with cracks closing and no signs of continued movement. This project demonstrates how non-invasive foundation stabilization techniques can be applied effectively in commercial settings with structural challenges.
