The technicians chose AP Lift 475 for the job. This material offers strong load-bearing capacity and cures quickly, minimizing plant downtime. Fast-curing was essential for a swift return to full operation, making AP Lift 475 the ideal solution for this repair task.
The repair began with the drilling of 3/4-inch holes. Workers drilled these holes roughly every 3 feet across the affected area. Then, they injected the repair material into each hole until the substance flowed beneath the slab from one drilled hole to the next. This method provided comprehensive coverage of the voids beneath the slabs, ensuring no areas remained untreated.
The entire repair took only one day to complete. After the work, the slabs were securely stabilized, and the pump equipment and workers were safe. The paper manufacturing company expressed satisfaction with the outcome. Due to the quick turnaround time, minimal disruption occurred. Most importantly, eliminating the dangerous voids created a safer work environment.
