What To Expect From Your New Concrete

What to Expect From Your New Concrete​

Concrete is a poured, natural-material product — a mix of cement, sand, stone, and water that cures into a hard, rigid surface. Unlike asphalt, it is rigid rather than flexible, and that changes how it behaves. Before we start, we want you to know exactly what a correctly installed concrete surface looks and does in its first year, so there are no surprises.

 

Your concrete will crack. This is normal.

Concrete is rigid, and it shrinks as it cures. Every concrete surface cracks — there is no such thing as crack-free concrete. To manage it, we cut and tool control joints (the straight grooved lines) into the surface. Those joints are designed to guide where cracks form; they steer cracking, they do not prevent it. Hairline cracks, shrinkage cracks, and cracks that appear at or run from the control joints are normal characteristics of concrete and are not defects.

 

Color and surface will vary.

Concrete is a natural product, and color varies from batch to batch, slab to slab, and even within a single pour. Shade differences, mottling, and minor finish or texture variation between areas are normal. You may also see efflorescence — a white, powdery mineral deposit that rises to the surface as the concrete cures. It is normal, harmless, and typically weathers away over time.

 

Finish, and matching existing concrete.

Unless your proposal specifies otherwise, your concrete receives a standard broom finish for slip resistance. New concrete will not match the color or texture of existing adjacent concrete — different age, different materials, and weathering all make an exact

match impossible. A visible line and color difference where new meets old is normal and expected.

 

It needs time to cure. Stay off it.

Concrete is placed wet and gains strength over several weeks. Even when it looks and feels hard, it has not reached full strength. Please observe these windows after placement:

• Foot traffic: keep off for at least 24 hours, potentially longer depending on environmental conditions.

• Vehicle traffic: keep all vehicles off for at least 10 days.

• Heavy loads: no heavy or continuous loads — large trucks, dumpsters, campers, loaded trailers — for at least 28 days.

• Protect the edges and corners. They are the weakest points early on and chip easily. Keep wheels and heavy objects off them.

 

No de-icing salt the first winter.

Do not use rock salt or chemical de-icers on your new concrete, especially through the first winter. De-icers accelerate freeze-thaw cycles at the surface and cause scaling, pitting, and spalling — that flaky, pockmarked look. Use clean sand for traction instead. Fertilizers also contain chemicals that damage concrete; keep them off the surface. Salt and de-icer damage is not covered under warranty.

​

Joints and edges.

Control joints are intentional and necessary — they are where we want any cracking to go. Expansion joints separate your concrete from adjoining structures so both can move. Edges are formed and finished by hand and will have slight variation. All of these are normal, not defects. Joint caulk or sealant is not included unless your proposal specifies it.

Where the new concrete meets the garage, house, or existing concrete.

Where your new concrete ties into a garage floor, the house, an existing slab, or a sidewalk, there will be a transition in height and a joint. A slight lip or grade change at these tie-ins is normal — the new surface has to meet what is already there, and those elevations are fixed. This is a characteristic of the work, not a defect.

​

Water and slight variation.

Your concrete is graded to drain, and we strive for proper drainage on every job. But no slab is a perfectly flat plane, and drainage also depends on the grades around it — so we cannot fully guarantee that no water will ever stand. Here is the standard we use: a low spot that holds up to about a quarter inch of water and clears within 24 hours of a rain is normal and within tolerance. A simple field check is the "quarter test" — set a quarter in the low spot, and if it is no longer covered by water 24 hours after the rain, it is draining fine. Water that drains slowly is still draining — the tell is sediment: slow drainage leaves the surface clean once the water is gone, while true ponding leaves behind a film of fine silt or sand, the kind of thing that rinses off a roof or a car.

Call us if: a low spot still has standing water a day after it rains (a quarter is still covered), a ring of fine silt or sand is left behind after it dries, a crack widens or lips up (one side sitting higher than the other) over time, the surface flakes or scales off in sheets, or a section settles noticeably. Those we will come look at.

​

Scheduling and delays.

Any dates we give you are estimates, not promises. Two things drive your schedule: weather and crew availability. Concrete work is weather- and temperature-dependent — rain, cold, and heat can move your pour date, and concrete has a seasonal window in Ohio. Your job is also worked into an active production schedule, so start and finish dates can shift, sometimes significantly and sometimes on short notice. We will keep you posted and get to your project as soon as we can — but please plan for flexibility. We would rather reschedule than pour in conditions that would compromise your slab.

​

Long-term care.

• Clean gasoline, oil, and chemical spills promptly.

• Sealing concrete periodically with a penetrating concrete sealer helps it resist water and salt. Ask us about timing.

• Use plastic-edged snow shovels and keep steel plow blades off the surface — they gouge and chip concrete.

• Hairline cracking will continue to appear over the years as the ground moves. Sealing and joint maintenance manage it. This is normal maintenance, not failure.
