Most of what goes wrong with concrete in this part of South Carolina starts under the slab, not on top of it. So the first thing we look at on any property is the ground: how it drains, where the clay holds water, how the lot slopes toward or away from the house. The pour itself is the short part of the job. The base, the forms, the joints and the cure are what decide whether a slab still looks right ten summers from now.
What we pour, build and grade
The work splits into five kinds of job, and plenty of properties need more than one of them.
Flatwork is the biggest share. If you are planning a new driveway or patio, a shop or garage slab, a sidewalk or a walkway to the front door, that is everyday work for us, for homeowners and for businesses that need parking pads, aprons and walks.
Stamped and colored concrete gives a patio, pool deck or front walk the look of stone, slate or brick in a single poured surface. Retaining walls and French drains deal with slopes and standing water, which on clay usually turn up together. Grading, clearing and site work get a raw or overgrown lot ready to build on, with silt fence along the low side to keep the soil where it belongs. Demolition covers breaking out and hauling off old driveways, slabs and walks so something better can go in their place.
Because one company handles the dirt work and the concrete, the grade under your slab is set by the same people who have to stand behind the slab.

Why concrete fails on red clay
Greenwood sits on red Piedmont clay. It is an expansive soil: it swells when it takes on water and shrinks back when a dry spell bakes it. A slab poured straight onto that clay rides up and down with the seasons, and concrete does not bend. It cracks, then one side of the crack settles, and a few years later there is a lip in the driveway that catches a tire or a toe.
The weather pushes on it from every direction. This area sees around 47 inches of rain a year, and a lot of it comes down hard in summer thunderstorms and the leftovers of tropical systems. Water that has nowhere to go sits against the slab edge and softens the ground beneath it. Summer highs run in the 90s, so fresh concrete sets fast and can crack across the surface if it is placed in the heat of the day and left to dry out. Winters are mild, but there are still a few dozen nights a year when water in the surface freezes and thaws, and that is enough to flake a weak finish.
None of that is a reason to avoid concrete. It is a reason to build it for this ground: a compacted stone base between the clay and the slab, control joints placed so the concrete cracks where we tell it to, an air-entrained mix for outdoor work, early pours in hot weather, a proper cure, and a grade that sends water away from the house and off the slab.
Where we work
Greenwood is home base, and most weeks we are somewhere inside the city or just off the bypass. We work across Greenwood County and the nearby Lakelands towns, from Ninety Six and Hodges to Abbeville, Ware Shoals and Laurens. That covers older in-town streets where the original driveways are narrow and broken, new subdivisions that need drives and patios behind fresh construction, farm and acreage properties that want a shop slab or a long drive, and the steep lots around Lake Greenwood where a wall and good drainage come before any concrete.
If you are not sure whether your address is inside our range, ask. The answer is usually yes.
How a job runs
It starts with a visit. Someone walks the property with you, measures, checks the slope and the soil, and asks what the concrete has to do: carry a work truck, hold a camper, drain a wet corner, or simply look good from the street. Every job is priced after someone has walked the ground and measured it, with the price in writing before a truck is ordered. You know the scope and the number before anything is torn up.
From there the order is the same on nearly every job. Old concrete or sod comes out. The ground is graded and compacted, stone base goes down and is compacted again, and forms are set to the right slope. The concrete is placed, struck off, floated and finished, joints are cut or tooled, and the slab is cured rather than left to bake. Forms come off, the edges are backfilled and the site is cleaned up. We tell you how long to keep foot traffic and vehicles off the new surface, because the first week matters more than most people expect.

Use the quote form on this page. It asks for your name, your phone number, the property address if you want to give it, and a message. In the message box, type what you have in mind: roughly how long and wide the driveway or slab is, what is there now, and anything the ground is doing that worries you, such as water standing after rain or a bank that is starting to slide. You can also reach us by phone at (864) 554-5164. The phone is answered around the clock, and the quote form on this site works any hour too. Either way, the next step is a visit to look at the ground and a free written quote.
