Concrete FAQ: the questions that don't belong to one service page
Eight answers here, twelve pointers to where the full answer lives.
Concrete questions answered here
Can concrete be poured on a Sarasota lot in the rainy season?
Yes, in the morning, with the forecast checked the night before and plastic on the truck. Pours here run from 7 a.m. and are finished and covered by early afternoon from June through September.
How soon can a screen cage go back on a new slab?
Seven days for anchors into a 4-inch slab; the edge beam or curb along the cage line is poured with the deck so the anchors have steel behind them.
Why does the estimate say 4,000 PSI when the code says 3,000?
Because 3,000 is the minimum and 4,000 finishes better in heat, scales less near salt and costs a few dollars a yard more. It's a working standard here, not a code requirement.
Will the new slab match my old slab's texture?
The finish can be matched (broom direction and coarseness); the color won't be exact. Plan the joint between old and new as a straight line, not a patch.
What is a proof roll?
Driving a loaded truck or roller over the subgrade before the base goes down to find soft spots; on Myakka sand it's how a contractor finds the wet pocket that would have become a settled panel.
Do I need to water new concrete?
Not if a curing compound was applied; if the crew wet-cures, the slab is kept damp for 7 days with burlap or sprinklers on a timer. Letting it dry out in the first week is the most common owner-caused defect.
Can concrete be tinted after it's poured?
Stained, yes: acid or water-based stains change the color permanently; paints and coatings peel. Integral color at the pour is more even.
Are there concrete trucks small enough for Siesta Key streets?
Mini-mixers and pump trucks handle the keys' narrow streets and weight-limited bridges; the estimate says which is planned and whether a pump adds cost.

The specification these answers assume
| Item | Value on this site |
|---|---|
| Thickness | 4 inches residential; 5 to 6 inches for concentrated loads |
| Mix | 4,000 PSI, water-cement ratio 0.45 or below, fiber included |
| Base | 4 inches compacted crushed limerock, 6 inches where the wet-season water table is within a foot |
| Lifts | 3 inches maximum per lift, each compacted to refusal |
| Reinforcement | #3 or #4 bar on chairs for vehicle slabs; fiber for walks and patios |
| Control joints | 8 to 10 feet, one quarter of slab depth, cut the same afternoon |
| Isolation joints | At the house, the pool beam, columns and existing slabs |
| Slope | 1/8 inch per foot minimum away from the structure |
| Cure | Curing compound or wet cure, 7 days; no vehicles for 7 days, heavy loads 28 |
Each line is argued on the concrete pillar and on the individual service pages. The two that decide most outcomes on this soil are the base lifts and the joint timing, and both are invisible a week after the pour.
