CONCRETE CRACKS. WE DECIDE WHERE.
Straightedge pours 4,000-psi air-entrained flatwork with the control-joint map drawn before the truck rolls — because a slab that cannot crack where you chose will crack where it wants to. Every rate on this page is per square foot, and every number survives daylight.
(555) 604-2213 · book@straightedge.example · 1,180 slabs placed across Harrow Bend and the toll-road valley
Pouring runs April through November. The 2027 calendar opens March 1 and the measure visits go in call order — March is usually spoken for by the thaw.
Services & rates
The rates — per square foot
Measured off your lot and held for sixty days. Forming, steel, finishing, jointing and wash-down live inside the per-foot number — the only extra we have ever charged is rock we could not see, and we telephone before we dig it.

rebar grid · control joints on a 10-ft map · broom or aggregate
Exposed aggregate$15.50

The slab book
Six pours from last season, chosen because each one shows a different finish doing its job. Ask on the phone and we will give you the street — our customers like their concrete more than we do.
How it goes
Form, pour, finish, cure
The same sequence on every job — the only variable is your project.
Day 0
Form & subbase
Six inches of three-quarter-inch aggregate compacted in lifts and proof-rolled with the loaded truck. Forms pinned to the string line, rebar chaired, and the joint map drawn on the plan where you can argue with it.
Day 1, 6 a.m.
The pour
One continuous placement — 4,000-psi air-entrained, five bags to the yard, batched at 5.7% entrained air. Screeded, darbied and edged while the sheen is still on the surface, because the sheen is the deadline.
Hour +6
Finish & the map
Broom, expose or stamp; then the control joints sawed within twelve hours on the grid you approved. Movement lands in the groove we cut — that is the entire promise of this trade, and it is a promise about geometry, not luck.
Day 28
Cure & handover
Sealed at full cure with a high-solid acrylic. Foot traffic at three days, the mower at five, vehicles at seven. The five-year joint-line warranty starts the morning you first park on it.
Straightedge was the only outfit that showed me a drawing of where the cracks would go. I thought that was a strange thing to be proud of until the neighbor’s slab, poured by someone else, did its own drawing.
They poured the courtyard between Saturday market and Tuesday opening. The joints are exactly where the plan said, and two winters of salt later the exposed aggregate still looks rinsed.
A crew of four arrived at six, and the one who quoted was one of them. The number never moved a dollar. I have had kitchen renovations I cannot say that about.
What the rate buys underneath
A slab is a roof over dirt. Ours sits on six inches of compacted aggregate, proof-rolled before a single form board is set — because concrete does not fix ground, it only reports on it, and we would rather read the report first.
Above the base: five inches for drives, four for walks, rebar on chairs at eighteen inches on centre, entrained air for the freeze-thaw cycle, and the joint map sawed inside twelve hours. None of it is optional, so none of it is an extra.
The five-year joint line
If a control joint spalls or the finish delaminates inside five years, we repair it — materials and labor. Concrete cracks; ours cracks where we told you it would.
Before you ring
Straight answers
When can we drive on it?
Vehicles at seven days, sealer and full strength at twenty-eight. Concrete makes roughly seventy percent of its strength in the first week — the calendar is chemistry, not a mood we are in.
So it WILL crack?
Every slab on earth moves. A jointed slab moves in the grooves: we saw within twelve hours of the pour, on a grid mapped to your slab’s geometry — usually every ten to twelve feet. The crack you never see is the one we sold you.
Do you color concrete?
Integral pigment in ten ranges, and exposed aggregate in three local stones. Both are batched at the plant, not dusted on top — the color goes through the slab, so a scratch cannot find a different colour underneath.
How small a job will you take?
About 200 square feet. Below that the truck minimums punish the per-foot price, and we will say so on the phone rather than pad the quote until it looks reasonable.
Winter pours?
Down to 40°F and rising, with hot water in the mix and blankets on the cure. Below that we re-book. A frozen pour is a warranty claim we would have manufactured ourselves.
