Commercial concrete on an office or corporate property covers everything people walk on, park on, and roll a hand truck across. Parking areas, aprons, loading and dumpster pads, entry landings, and the concrete sidewalk running from the lot to the front door. Some of it is plain flatwork. Some of it is stamped concrete or colored concrete at the entry, where the surface is part of what a tenant sees first. ADA items belong here too: ramps, level landings, and truncated dome panels where a walk meets pavement. Tear-out of the failed sections and hauling the old concrete off is part of it.
Underneath, a commercial slab is built heavier than the flatwork on a house. Delivery trucks and loaded dumpsters call for thicker sections, a compacted base, and rebar set on chairs rather than wire mesh alone. Mix and reinforcement get chosen for the load each area actually takes. Control joints are cut early and laid out so the cracks land where we put them. Pitch matters as much as thickness, because water that stands on a pad works its way into every joint. Finishes follow use: broom texture for traction on a sidewalk, exposed aggregate where grip and appearance both count.
Failures usually start below what anyone can see. A concrete sidewalk poured over soft fill will rock and lip at the joints within a few years, and no finish work fixes that later. Rebar dropped on the ground instead of tied up in the slab does nothing. Spalling often traces back to a surface troweled while bleed water was still sitting on it. Panels opened to truck traffic before the concrete has strength crack through the middle, not at the joints. Concrete installation is unforgiving that way.
Getting it right on an occupied property is mostly sequencing and forming. We pour in sections so a tenant keeps a door, a walk, and a way to the parking they use. Forms get set to hold the grade we want, not the grade the old slab settled to. Barricades stay up through cure.
