Concrete Driveways in Brentwood, TN

Concrete driveways in Brentwood often have a harder job than the ones in flatter towns. Many lots here are rolling, so the driveway climbs from the street to a side-entry garage, and every heavy storm sends water down its length. Underneath is clay that holds that water. When the base under a driveway is thin or missing, the clay softens, panels settle, and cracks open at the garage, along the edges and where the drive meets the street.

Signs it is time to replace

• Several panels have dropped, and water now pools at the garage door or against the house
• Cracks have opened wide enough that one side sits higher than the other
• The edges along the lawn are breaking off
• The surface is pitted or worn through in the wheel paths
• Runoff cuts a channel across the driveway or washes soil onto it
• The driveway is too narrow for the cars the household now owns

One sunken panel on an otherwise solid driveway can often be lifted instead. When settling, wide cracks and drainage problems show up together, replacement usually costs less over time than repeated patching.

What goes under the concrete

We break out the old driveway, dig out soft or organic soil, and bring in crushed stone compacted in lifts. That layer spreads the load and gives water a path out instead of letting it soak the clay. On a sloped driveway we look closely at where water enters and leaves: a trench drain at the bottom, a swale beside the drive or a downspout extension can keep runoff from undermining the slab.

HomeGuide's driveway cost guide says a residential driveway should be at least 4 inches thick, 5 to 6 inches for RVs or heavy vehicles, with edges of 6 to 8 inches. If a boat trailer, a work truck or a delivery route crosses the driveway, we thicken those areas. Rebar or welded wire keeps any cracks that form from separating, and joints are laid out so shrinkage cracks run where we want them.

At the street

Where a driveway meets the road, the apron may sit in the public right-of-way. Brentwood's Public Works Road Work Permitting page says excavation in the right-of-way or a public utility easement needs a permit, issued only after payment, and work on state routes such as Concord Road, Franklin Road, Moores Lane, Wilson Pike and Church Street also needs a TDOT permit. We check whether your apron falls under that rule and handle the paperwork before the tear-out is scheduled. Tennessee 811 marks utilities before we dig.

Finish choices

• Broom finish: the standard texture, with good grip on a sloped drive in rain.
• Exposed aggregate: the top layer is washed away to show the stone, which hides tire marks and adds traction.
• Stamped or colored borders: a decorative band along the edges or at the entry while the lanes stay broom finished.
• Smooth finish: we avoid it on sloped driveways because it gets slick when wet.

After the pour

HomeGuide advises waiting at least 7 days before driving on new concrete and the full 28 to 30 day cure before heavy vehicles, then waiting 28 to 30 days before the first sealer coat and resealing every 2 to 3 years. Keep downspouts pointed away from the edges, fill joints that open up, and avoid parking heavy equipment near the unsupported edges.
