Concrete Driveway Installation

Example builds › L&S Excavation › Services › Concrete Driveway Installation

A concrete driveway is one of the largest single pours on a residential property — and the one that gets seen and used every day for decades. Done right, it lasts 30-50 years and looks the same on year 25 as it did on year 1. Done wrong, it cracks across the middle by the second winter. We install concrete driveways across the Greater Chattanooga area with the same approach we use on every pour: subgrade first, reinforcement always, joints planned, finish to spec.

What's included

• Layout and stakeout of the driveway footprint with proper grade falls
• Site excavation and stripping of organic topsoil and unsuitable material
• Subgrade compaction to 95% standard Proctor
• Crushed-stone base course — typically 4-6 inches of compacted #57 or crusher run
• Edge forms set to elevation, including the apron transition to the road
• Rebar grid or wire mesh sized to the loading
• Vapor barrier under attached or heated slabs where called for
• 4,000 psi air-entrained concrete mix for our freeze/thaw zone
• Control joints cut at the right spacing (typically every 10-12 feet)
• Broom finish standard; smooth, salt, exposed aggregate, or stamped options
• Cure with wet-cover or membrane curing compound for the first 7 days

Concrete vs. asphalt vs. gravel

We build all three. The right choice depends on use, budget, and how the driveway connects to the rest of the property:

• Concrete — 30-50 year service life, highest upfront cost, lowest maintenance, looks finished
• Asphalt — 15-25 year service life, mid-cost, periodic seal-coating required (we don't pave asphalt — we coordinate with paving sub if needed)
• Gravel — 5-15 year service life with periodic top-up, lowest cost, rural and rustic look

For most residential builds in Hamilton County with a 50-100 foot driveway, concrete is the right long-term call when the budget allows.

Thickness, reinforcement, and slope

A residential concrete driveway in our area is typically:

• 4 inches thick for cars and light SUVs
• 5-6 inches for trucks, dual-axle vehicles, or RVs
• 6 inches with #4 rebar grid for heavy loads (dump trucks, equipment trailers)
• 2% minimum slope away from the house and toward the street, ditch, or yard

We hit each spec. We don't pour 3.5 inches and hope.

Why concrete driveways crack

Some hairline cracking in any concrete pour is normal. The cracks that ruin a driveway are the ones that telegraph through the slab in the first two years. The usual culprits:

1. Insufficient subgrade prep. Soft spots under the slab settle, and the slab cracks where the support fails. 2. Missing or wrong control joints. Concrete shrinks as it cures. If we don't tell it where to crack with joints, it picks its own spot. 3. Pouring on saturated subgrade or in extreme weather. Hot summer pours need timing; cold winter pours need protection. 4. Wrong mix design. Our freeze/thaw zone needs air-entrained concrete. Plain mix from a regional plant will spall by year five. 5. Skipped curing. Concrete that loses water too fast in the first 7 days cracks for the next 50.

We don't skip any of those.

The apron — where most driveways fail first

The transition from the driveway to the public road or street curb is where the most stress concentrates: heavy vehicle wheel loads, the angle change, the seam between your concrete and the public asphalt or curb. The apron usually needs:

• 6-inch thickness instead of 4
• Heavier rebar reinforcement
• A clean isolation joint between your slab and the curb
• A permit from the road department for the connection (we file it)
