Concrete Contractors in Decatur, IL

Decatur Concrete Contractors pours new driveways, patios, stamped concrete, sidewalks, steps and garage slabs in Decatur, Illinois, and nearby towns, and we fix or replace concrete that has cracked, settled or scaled. When you line up concrete contractors in Decatur for quotes, put the same three questions to each: what sits under the slab, what is in the truck, and how the surface gets finished and cured. The answers predict how the concrete will look after ten Central Illinois winters better than any sales pitch.

An older city with older concrete

Decatur built its economy on grain processing and manufacturing, and Wikipedia records its population peaking at about 94,000 in 1980. The housing still reflects that era. Census data summarized by Point2Homes puts the median Decatur home's build year at 1960, with 22.8 percent built in 1939 or earlier, 18.4 percent in the 1950s, and only about 4.6 percent since 2000. Roughly 74 percent are single-family detached houses, so most owners have their own driveway, front walk and steps to maintain.

Age changes the job. Many slabs from the middle of the last century went down on native soil with little or no stone under them, and older concrete was not always air-entrained. Street trees have had decades to push up walk panels, garage aprons have dropped, and stoops have tipped away from foundations. A lot of Decatur work starts with sorting what can stay, what can be lifted and what has to be broken out and rebuilt.

Wet, then frozen

Wikipedia's 1991 to 2020 normals for Decatur give a January daily mean of 26.9 degrees and a July mean of 75.6, with records of 113 above and 25 below zero. Average precipitation is about 40.4 inches a year; average snowfall is only about 13.6 inches.

Do not let the light snow fool you. Rain and melt keep slabs damp, and a damp slab that drops below freezing again and again is what breaks down a concrete surface. Water in the top layer expands as it freezes and pushes the paste apart. Add salt brine from cars and sidewalks and the surface starts to scale and pop out in chips. In summer the risk flips: hot, breezy afternoons pull water out of fresh concrete before it has cured, and the slab cracks from shrinkage.

What goes into every outdoor slab

• Stone underneath. Soft and organic soil comes out, and crushed stone goes in and gets compacted so the slab has a firm, draining bed.
• Built-in fall. Glaciers left Macon County mostly flat, so water rarely runs off on its own. We pitch forms so drives, patios and walks drain away from the house.
• Air-entrained ready-mix. Millions of tiny air pockets give freezing water space, which is what keeps the surface from scaling.
• Steel where it helps. Mesh on chairs for light slabs, rebar for driveways and garage floors.
• Joints on purpose. Cuts about one quarter of the slab's depth, laid out so panels stay near square and cracks land in the cuts.
• A real cure. The surface is kept from drying out too fast, and sealer goes on once the concrete is ready for it.

Repair or replace?

Not every bad-looking slab needs to come out. A sunken sidewalk panel or a tipped step on a solid base can often be lifted. A thin layer of scaling can sometimes be resurfaced. But when cracks are wide and growing, panels are broken into pieces, or the base underneath has washed out, patching just buys a year or two. We tell you which situation you have and why, and we price both options when both are real choices.

Public walks, aprons and permits

In most cities the public sidewalk and the stretch of driveway between that walk and the street sit on public right-of-way, and work there often needs a permit and has to meet the city's own standards. The City of Decatur and the villages around it, such as Mount Zion and Forsyth, each set their own rules. Before a pour date goes on the calendar, we find out what applies to your address and build the apron and walk to match.
