Replacing the builder driveway — the most common job in Summerville
Fifty-two percent of Summerville's homes were built after 2000, and the driveway the builder poured in a day on a scraped lot is cracking, sinking at the garage and holding water at the street. Here's what went wrong and what the replacement looks like.
Summerville's median home was built in 2001, and the subdivisions of that decade — the tracts off Bacons Bridge and Dorchester Road, the first phases of Carnes Crossroads, the neighborhoods around Sangaree and Ladson, the early streets of what became Nexton and Cane Bay — all got the same driveway: the lot scraped to grade, no stone base, no fabric, no reinforcement, three to three and a half inches of the cheapest mix on the truck, the apron poured in the same pass, and the whole thing finished before lunch. On the sand ridge downtown that might have lasted. On the Rains, Lynchburg and Coxville soils with water a foot down in winter, and on the Mouzon-Brookman-Wahee clays with their high shrink-swell potential, it didn't. Twenty years on the panels have dropped at the garage where the backfill settled, lifted at the walk where the clay swells, cracked across the middle where the wire never was, and the apron holds a puddle because the builder never graded it to the street. We replace more of these than any other job.
A replacement is the opposite of the original in every line. The old slab is broken out and hauled — or crushed and recycled as base, which the North Charleston yards do — and the ground underneath is finally dealt with: soft spots dug out, four to six inches of compacted stone over fabric where it's wet, the garage approach compacted in lifts so it doesn't drop again. Four inches minimum, six where the truck parks, welded wire or rebar on chairs through all of it, control joints cut the same day, a real slope to the street and away from the garage slab, and a curing compound. The apron gets its own permit from whichever authority owns the road, and the Town's 12-foot curb-cut and 30-percent coverage rules get checked, because the original builder may have exceeded both and the replacement has to comply. The HOA gets a drawing that matches the street. And when the slab is sound but simply sunk — common at the garage — we'll tell you that foam lifting is the honest answer at a third of the price.
What's included
Honest assessment first
Sunk but sound gets foam-lifted; cracked through, heaved and unreinforced gets replaced. We say which.
Break-out and recycling
The old slab broken out, hauled, and crushed as base where the recycling yards take it.
The base the builder skipped
Soft spots dug out, four to six inches of compacted stone over fabric, the garage approach compacted in lifts.
Thickness and steel
Four inches minimum, six at the parking area, welded wire or rebar on chairs — reinforced for the clay.
Permit and HOA package
The apron permitted with the right road authority, the Town's curb-cut and coverage rules checked, the ARB drawing submitted.
Joints, slope, cure
Control joints the same day, a grade that drains, curing compound against the summer heat.

Questions we get about builder driveway replacement
My driveway is only 18 years old. Why is it failing?
Because of what's under it — nothing. A thin unreinforced slab on scraped Lowcountry soil settles where the backfill was loose and heaves where the clay swells. The concrete isn't the problem; the base and the drainage are.
Can you just replace the bad panels?
Sometimes, if the rest is sound and the new panels can be tied in and matched. Often the whole thing is the same thin slab on the same ground and patching buys two years. We'll tell you which on site.
Will the HOA let me change the width or finish?
Within their standard, yes. Nexton, Cane Bay and Carnes Crossroads all have ARB rules on width, materials and color; Carnes limits the driveway to 10 feet in the right-of-way and 22 at the garage. We draw to their rule and submit it.
Does a replacement need a permit?
The apron does — Town, county or SCDOT, depending on the road. The Town also checks that the replacement meets the current curb-cut and lot-coverage rules even if the original didn't. We handle both.
How long is the driveway out of use?
Two to three days of work, then a week before cars. We stage it so you have the street and a path to the door throughout.
