How Thick Concrete Should Be, by Job
Not all flatwork carries the same load. The right thickness and slope depend on what the slab is for, and Johnson County clay and freeze-thaw make the basics matter more.
A 4-inch slab is the residential baseline for walks, pads and patios. Driveways, garage aprons and slabs that carry heavier loads are usually poured 5 to 6 inches thick. Either way, control joints every 8 to 12 feet on a 4-inch slab keep cracks in straight lines, an air-entrained mix helps the surface survive freeze-thaw, and walks within 10 feet of the house should slope at least 2 percent away from it.
Commercial walks that are part of an accessible route follow the 2010 ADA Standards: at least 36 inches wide, a cross slope no steeper than 1 in 48 (about 2 percent), and a running slope no steeper than 1 in 20 (5 percent). Anything steeper is treated as a ramp. Sidewalks in the public right-of-way fall under city rules too: in Overland Park, any construction or repair in the right-of-way requires a right-of-way permit. See concrete replacement.
- 4 inches for walks, pads and patios
- 5 to 6 inches for aprons and drives

Do I need a permit to replace the sidewalk in front of my house?
Often, yes. The sidewalk along the street is usually in the public right-of-way, and in Overland Park any construction or repair in the right-of-way requires a right-of-way permit. Other cities have their own rules, so check with yours.

Under the 2010 ADA Standards, an accessible walk must be at least 36 inches wide, with a cross slope no steeper than 1 in 48 (about 2 percent) and a running slope no steeper than 1 in 20 (5 percent). Anything steeper than that along the walk counts as a ramp and has stricter rules.
Do you do commercial concrete?
Yes. Commercial flatwork, sidewalks, ADA improvements, concrete repairs and curbs are part of what we do for businesses and property owners.
Can you replace a cracked or sunken sidewalk?
Yes. We break out and haul away the damaged sections, fix the base and pour new concrete. See concrete replacement.
