Why homeowners pick Tri-County
Built for Delaware weather, finished to last
Built to a real spec
6-inch slabs over a compacted stone base — the same spec we'd use on a municipal sidewalk, not the cut-rate version most replacement quotes hide.
On schedule, no surprises
Carlos Sr. or Carlos Jr. is on site every day, and you get a daily check-in on what got done and what's next. No ghosting between the deposit and the pour.
Finished by hand
Joints are snap-line straight, edges are tooled, and the broom finish is even across the whole slab. The kind of work that makes the neighbors ask who did it.
One written estimate
You get a clear quote with the scope, dimensions, and finish spelled out — not a verbal range that creeps up halfway through the job.
Details
Why Wilmington driveways fail — and how we fix that
Most failed driveways in Wilmington, Bear, and Newark aren't failing because of the concrete — they're failing because of what's underneath it. When a driveway was poured directly on top of clay sub-grade, with maybe an inch of stone for show, you get the same outcome every time: water gets in, freezes, heaves the slab, and within five winters the panels are tilted and the joints have opened wide enough to roll a quarter through.
A Tri-County replacement starts with a real base. We excavate down past the old slab, haul away every chunk of broken concrete, and bring in fresh DOT-grade stone that we compact in lifts. On a typical Wilmington driveway we're putting 4–6 inches of compacted base under a 6-inch reinforced slab, with rebar grid or heavy wire mesh tied so it sits in the middle of the pour — not on the dirt where it does nothing.
Once the base is set we form the apron to match your curb line, run control joints on a grid that's sized for your panels, and pour 4,000+ PSI mix. We finish with a light broom for traction, edge every joint by hand, and tape and cone the slab so it gets the cure window it needs. You drive on it after seven days, and the slab keeps getting stronger for another three weeks after that.
We replace driveways for two-car and three-car homes, townhouses on shared aprons, long country driveways, and short city pours — and we'll tell you straight if a section can be saved instead of replaced. We'd rather do one honest project than three corner-cut ones.

FAQ
Common questions
Don't see your question? Call (302) 419-3232 or send a quick note through the contact form — we usually reply same-day.
How long does a concrete driveway replacement take?
Most residential driveways in Wilmington are a 3–5 day project once we mobilize: one day to demo and haul out the old slab, one to set base and forms, one to pour and finish, then a sealed cure window before you drive on it. Larger or weather-affected jobs run longer; we give you a written schedule before we start.
How much does it cost to replace a concrete driveway in Wilmington, DE?
Pricing depends on square footage, thickness, base condition, and access — but most standard two-car residential driveways in New Castle County fall into a clear range we walk you through on the site visit. We give one written estimate with the scope spelled out and we don't mark up materials after the fact.
When can I drive on my new concrete driveway?
Foot traffic is fine after 24 hours. Passenger cars after 7 days. Heavy vehicles (trucks, RVs, contractor trailers) after 28 days, when the slab has reached full design strength. We tape, cone, and label the cure zones for you so guests do not cut the corner.
Do you replace driveways year-round?
We pour from early spring through late fall in Delaware. We can sometimes pour in winter with hot water and blankets, but we'll be honest with you — if forecast lows put the cure at risk, we'll schedule you for the next stretch of safe weather rather than gamble with your slab.
Do you tear out the old driveway?
Yes — tear-out, haul-away, and disposal are included in the price. You won't end up with a pile of broken concrete sitting in your yard waiting on a separate dumpster.
