Concrete Contractors Concord NC

A driveway for cars is usually four inches thick, but a trailer, an RV, or a work truck needs more. We pour five to six inches in the heavy spots, and we add steel so the slab holds together if the ground moves. Concord has plenty of race fans and truck owners who park big trailers at home, so we ask what you plan to park before we quote the job. We also look at the turn. A tight turn with a heavy trailer wears the edge fast, so we widen it or thicken the edge. The gravel base under the slab matters just as much as the concrete. We pack four to six inches of gravel in layers, and we add more where the clay is soft. Tell us the weight of your largest vehicle, and we will plan the slab to match it. A thicker slab costs more at first, but it saves money if a cracked corner means a full replacement later.

You cannot stop every crack, but you can control where they show up. Red clay in this area swells when it is wet and shrinks when it dries, and that movement pulls at the slab. We start by removing soft spots and packing a gravel base in layers, so the slab sits on even support. Then we add steel, cut control joints, and cure the slab slowly. Control joints are shallow cuts that tell the concrete where to crack, so the crack hides in a straight line instead of wandering across the middle. Good drainage helps too. We slope the slab and point the downspouts away from it. That is how concrete contractors Concord NC property owners call back handle clay: they plan for movement instead of hoping it stays away. Ask us to show you the joint layout before we pour. We also leave room at the edges for the slab to move, and we tie it to old concrete with steel pins.

Most sealers go on after the concrete has cured for about 28 days, though some breathable sealers can go on sooner. Sealing is not required for a plain driveway, but it helps. It keeps out water, oil, and stains, and it makes the surface easier to clean. For stained or stamped concrete, sealing is a must because the color needs protection from sun and rain. Pick a sealer that fits the job. A matte penetrating sealer is a good choice for a driveway, and a film forming sealer gives a glossy look to a patio. Do not seal wet concrete, or you can trap moisture and turn the surface cloudy. Pick a dry day, sweep the slab clean, and apply a thin coat. We can recommend products, and we can apply them for you. Plan to reseal every two to three years in Concord sun. If a sealer ever looks cloudy or peels, strip it and start fresh instead of coating over it.
