A new patio is a short job with long consequences. The pour takes hours. The cure takes weeks. Decisions on size, base, slope and finish are locked in once the concrete sets, so the planning stage matters most.
Formatlawrence Concrete is a referral service. It connects homeowners in Concord and the Concord area with independent local providers who build new concrete patios. The providers do the work. Formatlawrence Concrete explains the timeline, helps you line up written estimates on equal terms, and leaves the decision to you. There is no obligation to hire anyone you speak with.
Planning a Patio Before the Pour
Concrete rewards planning. A patio is concrete flatwork, meaning flat slabs poured at ground level. Once the truck arrives, the clock runs. Choices made weeks earlier decide how the slab looks in ten years.
The Pour-to-Cure Timeline
Here is what happens after the concrete is placed:
- Hours 0–2: Concrete is placed, leveled and smoothed. Mistakes are still fixable.
- Hours 2–8: Bleed water, the thin film that rises to the surface, evaporates. Finishers set the texture and cut control joints.
- Hours 24–48: The slab can usually take light foot traffic. Pets and kids stay off until then.
- Day 7: The slab has reached roughly 70 percent of its design strength. Light furniture is often fine.
- Day 28: Full design strength. Heavy loads can wait for this point.
Timing changes the outcome. Rushed finishing or poor curing can lead to dusting, scaling and cracks. Cure on schedule.
Why Homeowners Choose Concrete
Concrete is durable and shapes to almost any yard. It needs little upkeep. It also suits the stucco ranch homes, older bungalows and 1950s–1980s tract homes common in our region, where a slab patio often sits right off the back door.
What a New Patio Project Includes
Most projects follow four stages. Ask each provider to confirm all four in writing.
Layout and Excavation
The provider marks the footprint, removes sod and sets the depth. Access for equipment is checked now.
Base and Forms
Compacted gravel goes down first. Wood or metal forms hold the edges. Reinforcement, such as rebar or wire mesh, is placed before the pour.
Pour and Finish
The crew places concrete, levels it and applies the chosen texture. Joints are cut to control where cracks form.
Cure and Cleanup
The slab is protected while it hardens. Forms come off after a day or two. Sealer is applied once the surface is ready.
Sizing Your Patio
Start with how you will use it. A bistro table needs about 10 by 10 feet. A dining set with a grill needs closer to 14 by 16. Leave room to pull chairs back without stepping off the slab.
Size drives cost, so mark the outline with garden hose or spray paint first. Live with it for a few days.
Finish Options
A broom finish is the standard. It is textured for grip and simple to clean. Smooth troweled surfaces look sleek but can be slick when wet. Exposed aggregate shows small stones in the surface. Color can be mixed in or applied later.
Stamped concrete patios press patterns into the surface to mimic stone, brick or wood. They cost more and need sealing on a regular schedule. Ask providers to show finished examples.
Drainage and Your Foundation
Water should move away from the house. A typical target is a slight slope, about one-quarter inch per foot, running away from the wall. Patios that tilt toward a stucco wall invite moisture problems.
Slabs on grade and raised foundations react differently to wet soil. If you already see cracks or sagging near the house, bring in foundation repair experts first. A patio should not be poured over an unresolved issue.
Timing Around Weather
Our long dry seasons suit pouring, but hot, dry air pulls moisture out of fresh concrete too fast. Good providers pour early and keep the surface damp. Winter rain events are the bigger risk. Rain on a slab in its first hours can ruin the finish, so providers watch forecasts and schedule around them. Smoke seasons add ash, so ask when sealer will be applied. Mild coastal temperatures are easier on curing.
Comparing Estimates, Specs Side by Side
Two quotes can look far apart and still describe different jobs. Line them up on the same terms:
- Square footage and slab thickness (4 inches is common)
- Base depth and material
- Reinforcement type
- Finish, color and sealer
- Drainage work and haul-away of old material
- Start window and expected cure period
Request each estimate in writing. A written quote makes comparison simple and decisions calm.
Choosing a Provider
Ask about experience with patios like yours. Ask how they handle rain delays. Confirm that licensing and insurance requirements for your area are met, and verify them directly with the provider. Formatlawrence Concrete does not do the work or vouch for any provider, so confirm the details yourself.
If you are looking at concrete driveway repair instead, that is a different kind of job. This page covers new patios.
Caring for Your New Patio
The First Week
Keep vehicles, heavy planters and furniture off. Avoid de-icing salts, harsh cleaners and sharp dragging. Water the slab lightly only if the provider advises it.
Long-Term Upkeep
Sweep regularly and rinse spills quickly. Reseal on the schedule your provider gives, often every two to three years for sealed surfaces. Clear soil and leaves from edges so water keeps draining away.
What's Included
Layout and Excavation
The footprint is marked, sod is removed and the depth is set before anything else begins.
Base and Reinforcement
Compacted gravel and rebar or mesh give the slab a steady foundation that resists cracking.
Pour and Finish
Concrete is placed, leveled and textured, with joints cut to guide where cracks form.
Cure and Seal
The slab is protected while it hardens, then sealed when ready.
Typical Concrete Patio Costs in the U.S.

No obligationConcrete Patios FAQ
How long until I can walk on a new concrete patio?
Light foot traffic is usually fine after 24 to 48 hours. Furniture can often wait until about day 7. Heavy loads like a large grill are better kept off until the 28-day mark.
How thick should a concrete patio be?
Four inches is common for a residential patio. Heavier use or poor soil may call for more thickness. Ask providers to list thickness, base depth and reinforcement in each written estimate.
How do I compare concrete patio estimates?
Match square footage, thickness, base, reinforcement, finish, drainage work and schedule across all quotes. Differences in those items usually explain price gaps. Request every estimate in writing.
