IDOT's design manual lists what a curb is for. These are the jobs you'll notice.
Moves water
The gutter controls drainage, carrying runoff along the edge of the pavement.

Barrier or mountable?
IDOT's curb codes start with one of two letters. Here's what each one tells you.
| Barrier (B) | Mountable (M) | |
|---|---|---|
| The face | Vertical | Sloping |
| Heights in IDOT's standard | 6 or 9 in. | 2, 4, or 6 in. |
| Read it like this | B-6.12: a 6 in. curb with a 12 in. gutter | M-4.24: a 4 in. curb with a 24 in. gutter |

On streets designed for 45 mph or less, either type can be used, so your plans or your town's detail decide. Not sure which yours calls for? We'll go over the plans at your free quote visit.
How we build it
Set to line. Poured to profile.
A curb only works if it's on line and on grade. Here's the order.
- 01
Read the detail
The profile, the joints, and the concrete all come from your plans or your town's standard detail.
- 02
Grade & base
Excavated and graded, then set on an aggregate base. New Lenox's detail calls for 4 in. of crushed aggregate.

- 03
Set line & grade
Lines and grades are set so the gutter carries water to the drains.
- 04
Pour & shape
Poured and finished to the profile by the same crew that graded it.
- 05
Cut the joints
Sawed 2 in. deep 4 to 24 hours after the pour, then sealed. IDOT's standard keeps them 15 ft apart or less.

- 06
Cure & protect
Cured before it takes traffic, then kept free of deicers for its first year.

3,500 psi
Strength at 14 days
New Lenox's detail calls for at least 3,500 psi in 14 days, tested with cylinders from every day's pour.

Plan ahead
Every town draws it differently.
Get your town's detail
Towns set their own numbers. IDOT caps contraction joints at 15 ft; New Lenox's detail allows up to 20.

Confirm the profile
IDOT's standard lists 17 barrier and mountable profiles. Confirm which one your plans call for before the first pour.

Plan the openings
Where driveways, sidewalks, and paths reach the road, Will County's rules have the curb depressed or cut to IDOT standards.

Plan for salt
Gutters carry salty runoff. For severe exposure, NRMCA calls for 6–7% air, and at least 4,000 psi where deicers are used.

It's IDOT's shorthand. B means barrier, a curb with a vertical face. The 6 is the curb height in inches, and the 12 is the gutter width in inches.

A barrier curb has a vertical face, and a mountable curb has a sloping one. On streets designed for 45 mph or less, either can be used, so your plans or your town's detail decide.

Under IDOT's standard, contraction joints match the adjacent concrete pavement, never more than 15 ft apart. They're sawed 2 in. deep 4 to 24 hours after the pour, then sealed.

It depends on the detail. New Lenox's calls for 3/4 in. expansion joints:
- 10 ft either side of storm structures
- At curb returns and points of curvature
- Wherever new curb and gutter meets existing
- Every 50 ft on straight runs
Two 2 ft dowels go in at each expansion joint and wherever new curb meets old.

Under Will County's subdivision rules, it's required in every nonresidential subdivision, in residential ones where lots average less than 120 ft wide at the front, and where slopes exceed 5%. The required type is B-6.12.

Keep deicers off it for the first year, and never use ammonium nitrate or ammonium sulfate.
