What a driveway actually costs.
We publish our pricing so you don't have to guess. Some contractors hide the number until they're in your driveway with a clipboard. We don't.

Pricing above is for typical Solano County residential projects installed April 2026. Final price requires on-site measurement and a written contract per California Business & Professions Code §7159. Variables that affect price: existing concrete demo, slope/grading, access, soil conditions, permit scope.
Nine stages. Four payments. All §7159 compliant.
Every stage is physically verifiable. Every payment tied to work completed. California Business & Professions Code §7159 and §7159.5 protect you from contractors who bill ahead of work — our schedule is built to those standards.
Red-line measurement
Our foreman visits, measures, marks the slab outline with spray paint, photographs with dimensions drawn in red. No cost, no obligation.
Scope + total price
Written quote within 48 hours. Detailed scope, specs, exclusions, warranty, and "everything included" total. No hidden costs.
§7159 compliant
Written contract with scope, total price, timeline, warranty, 4-stage payment schedule, mechanics lien warning, and 3-day right to cancel per Civil Code §1689.7.
$1,000 deposit
Locks your pour date. Per §7159.5(a)(3), California caps down payments at the LESSER of 10% or $1,000. We never ask for more. Contractors demanding 30-50% upfront are violating state law.
USA ticket called first
Underground Service Alert (811) ticket required by Gov Code §4216 — 2 working days before dig. Existing concrete broken out. Subgrade excavated. Debris hauled same-day.
Base, forms, rebar
Compacted Class 2 aggregate base to 95% relative compaction. Form boards set to string line. #4 rebar at 18" OC both ways, lifted on chairs per ACI 318. Ready for your inspection.
~30% of contract
Due when demo, excavation, base compaction, forms, and rebar are physically in place and inspectable. Per §7159.5(a)(4), this payment covers work completed + materials delivered. Never for future work.
6-sack 4000 PSI
Townsend Concrete delivery with mix ticket verified. Placed, screeded, bull-floated, edged, troweled, broom-finished per ACI 302 flatwork standards. Control joints cut within 24 hours.
~50% of contract
Due when concrete is placed, finished, and control joints are cut. Largest milestone because it covers the biggest material + labor outlay. Still §7159.5 compliant: work completed, not advance payment.
Forms stripped, site clean
Walk-on traffic after 24 hours. Forms stripped. Site cleaned. You walk through with our foreman, list any punch items. Punch items corrected before final invoice.
Balance on completion
Due after walkthrough approval, punch items addressed, and unconditional lien release delivered per §7159(c)(4). Typical balance: remaining 14-20% of contract. Not a penny before walkthrough signed.
Written guarantee delivered
Warranty certificate hand-delivered: 1-year workmanship warranty. Unconditional lien release signed and given to you. Contract fully closed.
Full design strength
6-sack 4000 PSI reaches design strength at 28 days per ACI 318. Light vehicle at 7 days, full loads at 28. Your driveway is now engineered for 30-40 year service life.
⚖️ Why our payment structure is different
California Business & Professions Code §7159.5(a)(4) requires that progress payments match work actually completed + materials actually delivered. Contractors who collect 30-50% upfront are violating this section.
Your contract will include the exact 12-point boldface warning §7159 mandates:
"IT IS AGAINST THE LAW FOR A CONTRACTOR TO COLLECT PAYMENT FOR WORK NOT YET COMPLETED, OR FOR MATERIALS NOT YET DELIVERED. HOWEVER, A CONTRACTOR MAY REQUIRE A DOWNPAYMENT."
We cite it because we follow it. If another contractor's contract doesn't include this warning — that's a §7159 violation.
The $12/sqft driveway trap.
You may have seen quotes for $10–$14 per square foot. Here's what that price almost always means:
- 4-sack or 5-sack mix instead of 6-sack 4000 PSI (weaker, cracks faster)
- 4-inch slab instead of 6-inch (not rated for vehicles, will crack under repeated load)
- Wire mesh or no reinforcement at all instead of #4 rebar (mesh sinks to the bottom, does nothing)
- Unlicensed labor — no CSLB recourse if the job fails
- No permit, no workers' comp, no liability insurance — the risk is on your homeowners policy
- No expansion joints, improperly cut control joints — guaranteed crack patterns
That $12/sqft driveway typically cracks within 3-5 years of pour. Then you're paying to demolish AND repour. You pay twice to save once.
Bachi's pricing reflects the real cost of doing the job right the first time — licensed C-8 labor, full specs, proper insurance, pulled permits, and a written workmanship warranty that's backed up on paper.

Things homeowners ask us every week.
How much does a concrete driveway cost in Solano County?
Standard broom-finish driveways run $22–$28 per square foot installed. Stamped or decorative driveways run $28–$35 per square foot. A typical 2-car driveway (600 sqft) costs $15,000–$18,000 for broom finish. Price includes demo, excavation, compacted base, #4 rebar, 6-sack 4000 PSI concrete, control joints, and cleanup.
How long does a Bachi driveway last?
A properly installed 6-inch, 6-sack 4000 PSI driveway with #4 rebar lasts 30–40 years with minimal maintenance. Our spec exceeds California code minimum on mix strength, thickness, and reinforcement. That's why we back it with a written warranty.
Do I need a permit for my driveway?
Under California Building Code §105.2, residential driveways at grade level (not more than 30" above adjacent grade and not part of an accessible route) are exempt from building permit requirements statewide. This exemption is adopted by every Solano County city. Most residential driveway replacements do NOT require a building permit. Our C-8 license (CSLB #1074044) is the state authority to perform this work. If your project involves work in the public right-of-way (curb cut, approach work touching the street), an encroachment permit from the city may be required — in which case the property owner or general contractor is responsible for verifying and obtaining it. We'll tell you at the site visit if anything special applies.
Can you pour around my existing landscaping?
Yes. We can form custom edges, protect trees, work around irrigation, and handle tight access. Our foreman walks the site before quoting to flag any complications up front. No surprises on pour day.
What's the difference between broom, stamped, and exposed aggregate?
Broom finish is the standard — textured with a push broom for slip resistance. Most driveways. Stamped concrete is pressed with patterns (slate, cobblestone, wood plank) and colored. Exposed aggregate reveals decorative stones by washing the cream off the surface. All three use the same structural spec underneath — just different finishes.
How long before I can park on the new driveway?
Walk-on within 24 hours. Light vehicle after 7 days. Full design load (heavy trucks, RVs) after 28 days. Concrete gains strength over time — we'll tell you exactly when each milestone is reached for your specific pour.
