Concrete Contractors Mount Holly NC

We can extend it, but a perfect match is hard. Old concrete fades and darkens, and new concrete looks lighter at first. After a year or two in the sun, the colors blend more. We cut a clean edge on the old slab, drill holes, and set steel dowels so the new section ties into the old one. That keeps the two pieces from pulling apart. Then we pour, finish, and cut a joint along the seam. If your old driveway has deep cracks or has sunk, we may suggest replacing it, because a new extension will not fix a failing slab. We also look at drainage. A wider driveway can send water toward the house if the slope is wrong. We check the grade before we quote the job. If you want a bold change, a border or color band can turn a mismatch into a design choice. Concrete contractors Mount Holly NC owners should ask about color matching and about steel dowels at the seam.

Flaking, also called scaling, happens when the top layer breaks loose in thin pieces. The usual causes are too much water in the mix, finishing while bleed water is still rising, and deicing salt on young concrete. Freeze and thaw cycles make it worse, because water in the pores expands as it freezes. Mount Holly does not have many hard freezes, but a few each winter are enough to damage a weak surface. Pressure washing too hard can strip the top, too. We prevent scaling by using a proper mix, waiting for the bleed water to leave before we trowel, and curing slowly. For an older slab that is already flaking, a sealer may slow the damage, and a thin overlay can renew the surface. A badly scaled slab may need replacing. Keep salt off new concrete for the first winter, and sweep sand off the surface in spring so it does not scratch the top. A good sealer helps a lot here.

Yes, with extra planning. Low ground near a creek can stay soggy, and heavy storms can raise water levels fast. We look at the yard after rain and ask neighbors where water collects. Near a creek, some lots have buffers or floodplain rules, so check with the county before you build. If a slab is allowed, we raise the grade with compacted stone, slope the surface away from the house, and add a drain or a swale where it helps. We use thicker concrete and steel in wet areas. We also avoid blocking a natural drainage path, because that can send water into a neighbor's yard. Gutters and downspouts should empty well away from the slab. Sometimes a French drain or a small catch basin solves a wet yard better than concrete alone. Tell us where the water goes, and we will tell you honestly what we think. A short walk around the yard after a storm shows us more than any drawing could.
