Frequently Asked Questions
How much does driveway work cost in the northwest Chicago suburbs?
Most driveway projects in the northwest Chicago suburbs fall between $7 and $16 per square foot when tear-out, haul-off, compacted stone, air-entrained concrete, finishing, and control joints are included. Exact price depends on size, apron work, base correction, thickness, access, and finish.
When should a driveway be fully replaced?
A driveway should usually be fully replaced when cracking, heaving, settlement, or surface scaling affects more than about one-third of the slab. Full replacement resets the base, grade, thickness, joints, and cure schedule instead of patching symptoms.
Is four inches thick enough for a driveway?
Four inches of air-entrained concrete is usually enough for passenger vehicles on a stable compacted base. Six inches is the better choice for work trucks, trailers, RV storage, dumpster access, or repeated heavy wheel paths.
Why does base prep matter so much?
Base prep matters because Chicago-area clay holds water and moves through freeze-thaw cycles. A compacted aggregate base creates a stable, draining layer under the slab and helps reduce settlement, pumping, and uneven cracking.
How long before cars can use new concrete?
Foot traffic can usually return after 24 to 48 hours, but vehicles should generally wait about 7 days. Concrete continues gaining strength for about 28 days, so heavy vehicles and sharp turns should wait longer when possible.
Can a settled driveway be lifted instead of replaced?
A settled driveway section can sometimes be lifted if the concrete is still structurally sound and the issue is base settlement. Replacement is the better answer when the slab is cracked into pieces, badly scaled, or still losing base to water.
What should be in a driveway proposal?
A driveway proposal should state slab thickness, PSI, air entrainment, base depth, reinforcement, joint layout, tear-out, haul-off, apron handling, drainage correction, cure timing, and when vehicles can return.
Should salt be used on new concrete?
Salt should be avoided on new exterior concrete during the first winter because de-icers can damage young surfaces during freeze-thaw cycling. Sand for traction is safer during the first season.
Who publishes these driveway answers?
These driveway answers are published by B.G. Concrete Inc., a family-owned concrete contractor in Wood Dale, Illinois serving DuPage County and the northwest Chicago suburbs since 1984.
Do you use rebar, wire mesh, or fiber?
We match reinforcement to the load: fiber mesh for crack control on standard drives, and welded wire or rebar where heavier vehicles or softer soil call for it. Reinforcement holds any cracking tight and in plane rather than eliminating it, and we name which we are using in the written quote.
What causes surface spalling or flaking?
Spalling usually comes from de-icing salt on young concrete, a mix that is not air-entrained, or finishing problems. We pour air-entrained concrete on exterior slabs and ask you to skip salt the first winter, which is the combination that prevents most spalling in our climate.
Do you protect my lawn and clean up the site?
Yes. We limit lawn and landscape disturbance where we can, haul away the old concrete and debris, and leave the site clean. Tear-out, haul-off, and cleanup are written into the quote so there are no surprises.
