Case Study: Commercial Lift
Background
An oil field repair shop was originally built on a marshy site, which led to long-term foundational challenges. Over the years, the concrete floor began showing significant signs of deterioration. Voids developed beneath the slabs, sections became misaligned, trip hazards emerged, and stress cracking spread across the surface. These issues created growing operational and safety concerns within the facility.
The Problem
As a high-use industrial repair facility, the shop required a load-bearing floor capable of supporting heavy machinery and equipment on a daily basis. Due to ongoing settlement and void formation, the slabs were fracturing, shifting, and creating uneven surfaces. This posed serious health and safety risks for employees and compromised the structural integrity of the floor.
The shifting slabs could no longer reliably support the weight of heavy loads being moved in and out of the shop. With both safety and productivity at risk, immediate corrective action was necessary.
The Alternative
Full concrete removal and replacement was considered. However, this option would have required significant demolition, extended downtime, and major disruption to daily operations. Given the critical nature of the facility’s work, shutting down for an extended period was not a practical solution.
The Solution
CR Concrete Lifting recommended polyurethane structural foam injection as an efficient and long-lasting solution. To demonstrate the effectiveness of the process, a test area was first selected and completed. Once the trial successfully re-leveled the slabs and eliminated trip hazards, the project proceeded with a targeted focus on the facility’s heavy-load bays, where the greatest structural demands existed.
Polyurethane foam was strategically injected beneath the slabs to fill voids, stabilize the underlying soil, and realign misaligned sections. This non-invasive and fast-acting method restored structural support without the need for major demolition or prolonged shutdown.
The Results
The entire project was completed in just three days with minimal disruption to operations. The load-bearing capacity of the floor was fully restored, allowing for the safe movement of heavy machinery and equipment. Trip hazards were eliminated, significantly improving workplace safety for employees.
By choosing polyurethane lifting instead of full replacement, the client secured a cost-effective and durable solution that extended the life of the existing concrete while maintaining uninterrupted business operations.
