The job

An entire floor of a downtown Louisville high-rise, stripped to the structure for a new tenant build-out. The slab underneath was original to the building — sound, but rolling and out of plane by more than any finish floor would forgive. Before walls, ceilings or flooring could go in, the whole floor had to be brought to one flat plane.

We did it as a single pump-fed pour of UZIN NC 888 self-leveling underlayment. Screed rails were set across the slab to fix the finished height, the pump was staged at the core, and the crew walked the hose out across the floor bay by bay — mixing, pumping, raking and smoothing in one continuous operation so there were no cold joints between placements.

Floor preparation was self-performed by Trade Mark Floors, our UZIN certified flooring subsidiary. On a high-rise that matters: one crew, one hoist schedule, and no hand-off between the company that flattens the floor and the company that finishes it.

Pump, hose, rake — in sequence

The floor before the pour. Hose run out from the pump and the screed rails set across the slab so the underlayment lands at one height.
