Concrete FAQ for Rockford, IL
Direct answers to what Rockford property owners ask before they hire a concrete contractor, grouped by cost, construction and care.
What do Rockford owners ask about concrete cost, permits and planning?
How much does concrete work cost in Rockford, IL?
Plain broom-finish concrete in the Rockford area typically runs $8 to $14 per square foot installed for a new driveway, patio or garage slab. Removing old concrete adds about $2 to $4 per square foot, stamped work runs $14 to $24, and lifting a sunken slab usually costs $3 to $16 per square foot.
Do you need a permit for concrete work in Rockford?
It depends on the job and the municipality. Work in the public right-of-way, such as a driveway approach or the sidewalk along the street, generally needs a permit. Foundations and structural slabs do too. Rockford, Loves Park, Machesney Park and unincorporated Winnebago County each have their own rules, so check with the building department first.
How long does a concrete driveway last?
A concrete driveway built on a compacted stone base with air-entrained concrete and proper joints commonly lasts 25 to 30 years, and many go longer. What shortens that life in the Rockford area is deicing salt on young concrete, water standing against the slab, and heavy trucks on a four-inch pour.
Who calls JULIE before concrete work starts?
Whoever is doing the digging. JULIE is the free Illinois one-call system that sends utility companies out to mark buried gas, electric, water and communication lines. State law requires the call before excavation, and the marks take a few days. On a contracted job the contractor normally makes the request.
What do owners ask about how a slab should be built?
How thick should a concrete driveway or slab be in Rockford?
Four inches of concrete over four to six inches of compacted stone is the usual minimum for a driveway, patio or sidewalk in Rockford. Go to five or six inches where pickups, trailers, RVs or delivery trucks park. In Winnebago County's freeze-thaw climate the base and the air-entrained mix matter as much as the thickness.
What is air-entrained concrete?
Air-entrained concrete contains billions of microscopic air bubbles, created by an admixture added at the ready-mix plant. When water inside the concrete freezes and expands, the bubbles give it room. Exterior concrete in northern Illinois is typically ordered with 5 to 7 percent air. Interior floors that get a hard steel-trowel finish are not air-entrained.
Is rebar or wire mesh better in a concrete slab?
Rebar is stiffer and easier to keep in position, so it is the usual choice for driveways and anything carrying vehicles. Welded wire mesh is fine for patios and walks if it is supported on chairs. Neither stops cracks. Steel holds a crack tight so the two sides stay level.
Why does new concrete crack?
Concrete shrinks slightly as it dries, and that shrinkage has to go somewhere. Control joints are cut so the slab cracks along a straight line at the bottom of the joint. Random cracks usually trace back to joints spaced too far apart or cut too late, a soft base, or too much water in the mix.
What do owners ask about timing, weather and care?
How long before you can drive on new concrete?
Keep passenger cars off a new driveway for about seven days, and longer when temperatures are in the 40s or 50s. Foot traffic is usually fine after 24 to 48 hours. Hold heavy loads such as moving trucks, RVs and dumpsters for 28 days, when the concrete reaches its design strength.
Can concrete be poured in cold weather in northern Illinois?
Yes, with precautions, and never on frozen ground. Once temperatures drop toward freezing, the ready-mix plant heats the water and can add a non-chloride accelerator, and the finished slab is covered with insulated blankets for several days. Most exterior flatwork around Rockford is poured between April and November.
When should new concrete be sealed?
Wait about 28 days, until the slab has cured, then apply a penetrating silane or siloxane sealer before the first winter. It soaks in and slows water and road salt from entering the surface. Reapply every few years. Decorative film-forming sealers on stamped concrete need a fresh coat every two to three years.
What is the best time of year to pour concrete in Rockford?
Late spring and early fall are the easiest, with daytime temperatures between about 50 and 75 degrees. Summer pours work with early start times and prompt curing. Concrete placed in October should be sealed or at least well cured before road salt reaches it, and it should not see deicers its first winter.
