Marcus has poured over 2.1 million square feet of warehouse and distribution center floor. He reads a floor like a topographic map — knows where water will run before the truck backs in.
"Control joints at 10-foot intervals aren't a code minimum — they're the difference between a floor that cracks where you want it to and one that cracks wherever it wants. On a 40,000 sq ft pour, that's 160 joints placed by hand. Every one matters."

How a floor gets
mirror-flat.
Three finishing phases, each requiring different tools, timing, and judgment. Here's what happens after the truck backs in.

Bull Float
Initial Surface Leveling
Immediately after screeding, the bull float closes the surface, embeds aggregate, and removes high spots. A 10-foot magnesium bull float is standard on commercial pours — aluminum leaves drag marks that show in the final polish.
Tool Length
10 ft mag
Timing
10–20 min
Pass Count
2–3 passes
Timing
Used within 10–20 minutes of placement, before bleed water rises.
Result
Flat, closed surface ready for edging and jointing.
