Pour day
Concrete goes in wet, then it is screeded, floated and troweled while it is still workable. The surface is dark, glossy and soft, so everyone stays off.
See the serviceThe slab holds its shape. We protect it from rain, freezing and fast drying, and cut joints at the right time so cracks stay in line.
See the serviceLight foot traffic is often fine after a couple of days, with care. Furniture and pets can wait a little longer.
See the serviceAbout a week in, many driveways can take cars. Heavy trucks and equipment should still wait.
See the serviceStrength is climbing fast. Colder weather slows it, and warm weather speeds it up.
See the serviceThis is the standard point where concrete reaches its design strength, about four thousand psi on a common residential mix. Sealing usually waits until here.

What is your specialty?
Stamped concrete. We make patios, driveways and walkways look like natural stone, brick, tile or slate in more than a dozen colors plus custom blends. We also pour and repair plain concrete of every kind.
Where do you work?
We are based in Firestone, Colorado, and serve homes and businesses across Denver, Longmont, Boulder, Broomfield, Greeley, Loveland and everywhere within about thirty miles.
Do you offer free estimates?
Yes. We come to your property, measure, talk through the options and put the estimate in writing, free.
Do you do commercial work?
Yes. We handle residential and commercial concrete, including parking areas, sidewalks, dumpster pads and shop floors.
Can you repair or reseal existing concrete?
Yes. We repair cracks, level sunken slabs, replace failed concrete, apply sealer and overlay existing concrete to renew it.
How long before I can use new concrete?
Light foot traffic is often fine after a day or two and cars after about a week, and cold weather stretches that. We give you dates for your pour.
What days are you available?
Our team is available seven days a week to answer questions about your project from start to finish.
How is concrete affected by Colorado weather?
Clay soil, freeze-thaw cycles, dry wind and de-icers all matter, so we build a solid base, plan joints, protect pours from fast drying and recommend sealers.
