Multi-Story & Commercial Pours
Service Overview
Commercial pours run on tight windows — concrete temperature, labor on the floor, and the crane or forms waiting their turn. A pump truck with the wrong reach or a no-show operator doesn't just slow the pour. It bleeds into the next shift, adds a cold joint where you didn't design one, or gets a load rejected when the batch clocks out.
Grayline's 47-meter Alliance boom covers most multi-story work in a single setup — street-level decks through mid-rise, parking structures, and tilt-up commercial. One truck, one operator, one call. No coordination tax between dispatch and the job trailer.
Why the Right Pump Matters on Multi-Story Work
Commercial pours aren't just big - they're time-sensitive and stackable. One missed window cascades into three lost days and a structurally compromised deck.
Boom pumps place 100–150 yd³/hour; crane-and-bucket averages 25–40 yd³/hour
Ready-mix concrete has a ~90-min window from batch plant to discharge before slump loss
Cold joints from pour delays can reduce deck shear strength by up to 30%
47m of vertical reach covers decks up to the 7th floor without repositioning
Rejected loads cost $150–300 per cubic yard in material alone - before schedule hits
What’s Included in This Service
Every commercial pour with Grayline includes: on-site walkthrough 24–48 hours before pour day, boom-position modeling, operator–mixer coordination, line-pump backup on call if the boom can't clear a setback, pour hand-signaling, wash-down and cleanup before we roll out, and a post-pour volume reconciliation so your super's numbers match the plant's numbers.
