A Homeowner's Guide To Concrete

Concrete is a hard, durable paving material made from portland cement, sand, crushed stone, and water. Portland cement is the powdery binder that hardens through a chemical reaction with water. When concrete is placed, finished, and cured correctly, it can serve as a long-lasting driveway, walk, or patio surface. Bruck Construction installs and repairs concrete driveways for homeowners.

What concrete is made of

Concrete combines portland cement with sand, aggregate, and water. Aggregate is the crushed stone that gives the mix its bulk and strength. The paste formed by cement and water coats the aggregate and hardens as the cement reacts with the water. The mix proportions and the amount of water used affect strength and durability, which is why the mix specification matters as much as the finish.

How concrete is placed and finished

Crews prepare the subgrade, install forms to hold the edges, and often place a layer of compacted gravel for drainage and support. Reinforcement, when used, is positioned in the slab before the pour. The concrete is placed, leveled with a straightedge, and floated to smooth the surface. The final texture, such as a broom finish for traction, is applied while the surface is still workable.

Control joints prevent random cracks

Concrete shrinks slightly as it cures, and it will crack somewhere if it is not given a planned place to crack. Control joints are grooves cut into the slab at set intervals so that shrinkage cracks form in straight, controlled lines. Joint placement is part of sound design, and a good installer will explain where the joints go before the pour.

Curing is the step that is often overlooked

Curing is the process of keeping fresh concrete moist and at a reasonable temperature while it gains strength. Concrete that dries too quickly can develop surface cracks and lose strength. Protection from rain, heat, wind, and freezing is part of a proper installation, and the schedule should account for it before the slab is walked on or driven over.

Concrete and Ohio freeze-thaw cycles

Ohio freeze-thaw cycles put heavy demands on concrete. Water that soaks into the surface freezes, expands, and can cause scaling, which is when the surface flakes, or spalling, which is when chunks break away. Air entrainment, a controlled amount of tiny air bubbles in the mix, helps concrete resist this damage. Keeping water off the slab, draining it away from the edges, and repairing cracks promptly also reduce the moisture that gets into the concrete.

Concrete compared with asphalt

Concrete is rigid, holds its shape well, and offers many finish options, which is why many homeowners choose it for appearance. Asphalt is flexible and can be repaired in sections. Both can be a good choice, and the right answer depends on your site, drainage, use, and budget. Our guide to asphalt covers the other side of that decision.

Repairs and the guarantee

Cracks, scaling, and settlement can often be repaired, but the cause matters. A repair that ignores drainage or the base will usually fail again. Bruck provides a 1-year guarantee on all asphalt and concrete work, and the written estimate describes the scope of each job.

Maintenance that helps

• Keep water draining away from the slab edges.
• Fill cracks before water can reach the base beneath them.
• Use de-icing products sparingly, and choose products suited to concrete.
• Keep heavy loads off fresh concrete until it has cured.

Following these habits helps a slab reach its full service life.

Frequently asked questions

When can I drive on new concrete?

Vehicles should wait until the concrete has gained enough strength for the load. The timing depends on the mix, the weather, and the design of the slab. Your installer should give you a clear schedule before the pour.

Why did my concrete crack?

Some hairline cracking is normal as concrete cures, especially near control joints. Cracks that are wide, uneven, or growing can point to a base problem, a drainage issue, or a curing problem. An on-site look is the best way to tell the difference.

Can concrete be poured in winter?

Concrete can be placed in cold weather with added protection, but freezing before it gains strength can damage it. Many projects are scheduled for warmer months for that reason.
