Concrete Driveways in Greenwich, CT
We pour and replace concrete driveways for homeowners in Greenwich, Connecticut. That covers the full job: breaking out and hauling the old slab, excavating and compacting a stone base, setting forms, tying steel, placing the concrete and cutting the joints, plus the apron where your drive meets the road. The result is a flat, properly drained driveway that carries vehicles without cracking apart in its first few winters.
What Does a Driveway Job Actually Involve?
Most of the work happens before any concrete shows up. We strip the existing surface and the organic soil under it, then cut to a grade that sheds water away from your garage and your foundation, not toward them. Six to eight inches of processed stone goes in and gets compacted in lifts, because a base dumped in one thick layer never compacts all the way through.
Forms get set to a string line so the finished surface is where we said it would be. Reinforcement — rebar on a grid, or heavy welded wire on chairs — sits in the middle third of the slab where it can actually hold a crack closed. Residential drives get poured four to six inches thick depending on what parks on them, in a 4,000 psi air-entrained mix. We finish with a broom texture for grip on a wet hill, cut control joints within a day, and seal the slab before its first winter.
When Do You Need a New Driveway Instead of a Patch?
There are five signs that the slab has stopped being repairable:
- Cracks wider than a quarter inch that run most of its length.
- Sections at different heights, where one panel has dropped or heaved past its neighbor.
- Panels that rock or click when you step or drive on them.
- Surface spalling down to the stone across a large area, not just one patch by the road.
- Water pooling on the drive or running toward the garage after every rain.
Two or more of those together almost always mean the base underneath has washed out or is moving with the frost. Pouring new concrete over a bad base buys you a few seasons at full price.
Why Do Driveways Fail in This Town?
Greenwich driveways take an unusual beating. They get salted heavily every storm, and cars track more brine up from the Post Road and the hill routes. Chloride works down through the surface and rusts the steel inside, which swells and pushes the concrete apart. Meanwhile the glacial till under most properties here holds pockets of clay that trap water, so the ground itself lifts as it freezes and drops as it thaws.
Add root pressure from the big oaks and Norway maples lining these streets, and a long backcountry drive with a real slope to it, and you have a slab being pushed from underneath, corroded from above and drained badly in between. None of that is exotic. It just has to be designed for.
What Affects the Price of a Concrete Driveway?
Square footage is the starting point, but it is rarely what moves the number most. Thickness matters, since a drive rated for a delivery truck is heavier construction than one for two cars. Demolition and disposal of the old slab is charged by weight at the transfer station. Ledge is the big one north of the Merritt Parkway — hitting rock where we planned to excavate means breaking or redesigning. Access counts too: if a mixer cannot back down a narrow tree-lined drive, the concrete has to be pumped or buggied in. Finally, if water caused the original failure, drainage has to be part of the job.
Can a Driveway Be Repaired Instead?
Often, yes, and we will say so when it is true. A slab with a sound base and a tired surface is a candidate for routing and filling the cracks and resurfacing, at a fraction of replacement cost. One settled panel can be lifted back to grade rather than replaced. The decision is about the base, not the appearance.
If you want the drive to look like something other than gray concrete, the apron and borders can be stamped and colored while the field stays broom-finished for traction.
Driveway Questions We Get
How long before I can park on it?
Walk on it after 24 to 48 hours. Keep vehicles off for a full seven days, and heavy trucks off for two weeks. Concrete reaches most of its strength at 28 days.
Will it crack?
Every concrete slab cracks. The job is to control where. Cut joints give the slab a planned place to relieve stress, so what you get is a straight line in a joint instead of a jagged one across the middle. Anyone promising you a crack-free driveway is selling something.
Do I need a permit?
Often yes, particularly where the apron meets the town right-of-way or where grading changes drainage. We pull what the Town of Greenwich requires as part of the job.
Should I seal it, and how often?
Yes. Seal after the first full cure, then every two to three years. In a climate with this much salt exposure, sealing is the cheapest thing you can do to add years to the slab.
