Evidence Before Beauty.

Every project leads with tolerances, volumes, and crew data — then the photograph. Because the people who sign purchase orders read specs first.

Superflat tolerance achieved

A 420,000 sq ft tilt-up warehouse pour executed across four continuous overnight pours. The facility manager specified a superflat floor for automated guided vehicle (AGV) operations — tolerances that leave no margin for deviation.

Grit mirror polish level

An architect-specified polished concrete floor for a 12,000 sq ft luxury retail flagship. The finish required a 1,800-grit mirror polish with dye integration — the kind of surface that makes product photography redundant because the floor itself reflects the merchandise.

Phased pours, zero production loss

A complete 85,000 sq ft mill floor replacement for a heavy manufacturing facility. The existing slab had deteriorated from forklift wear and chemical exposure over 30 years. The replacement required coordinating around active production lines, pouring in sections with zero disruption to the 24/7 operation.

Client Record // Verified Results

The Numbers Don't Lie.

General contractors, architects, and facility managers who put their reputation on the line by specifying Slab — and got exactly what was promised.

Derek Calloway, Senior Project Manager at Calloway General Contracting
FF 50
Delivered vs. FF 35 specified
We spec'd Slab for the Meridian distribution center after seeing their FF/FL numbers. Most crews promise 35 and deliver 22. These guys hit 50. The AGV operation went live without a single recalibration event — that's never happened on a first pour.

Sample board match, first pass
The Vela flagship was my first time specifying polished concrete for a retail build-out at this budget level. I needed a crew that understood the difference between a 400-grit and an 1,800-grit finish. Slab's team didn't just understand it — they matched the architect's sample board on the first pass.

Zero defects in service
We were replacing 85,000 square feet of mill floor in a facility that runs three shifts. The ask was zero production downtime. Slab phased the pour across 12 sections, worked nights and weekends, and never once caused a line shutdown. The new floor has been in service 18 months with no cracking, no joint failure.
