Commercial Concrete Lifting at NWTC Niagara Campus In Niagara, WI

Before: Sinking Concrete Threatens Critical HVAC Equipment

At NWTC's Niagara campus, a small but essential concrete pad supporting a commercial AC compressor unit had begun to settle and tilt unevenly. Over time, shifting soils beneath the slab caused it to sink by several inches—putting strain on the compressor lines and creating long-term risk for the system’s performance and longevity.

The college’s facilities team wanted a solution that was fast, clean, and wouldn’t require moving or disconnecting the equipment.

After: Leveled, Stabilized, and Protected with PolyLevel®

Sure-Dry installed the PolyLevel polyurethane foam lifting system, which allowed our team to:

• Lift and re-level the sunken concrete pad with precise control

• Minimize vibration and disturbance to the attached AC unit

• Avoid costly removal or shutdown of the HVAC system

• Achieve long-term slab stabilization with minimal downtime

The work was completed in just a few hours, and the pad is now perfectly level and structurally sound, protecting both the concrete and the heavy equipment it supports.
