Walkways and Curbs Built to Code

Concrete curbs, sidewalks, and pavement work for commercial and municipal projects in the Illinois Valley and surrounding areas.

Commercial properties and public spaces in the Illinois Valley need walkways and curbs that meet ADA slope requirements, handle weather cycles, and stay level under foot traffic and occasional vehicle contact. Gillan Construction LLC installs concrete sidewalks, curbs, and pavement sections using code-compliant construction methods that produce durable, accessible surfaces.

This service covers new sidewalk installation, curb and gutter sections for parking lots and streets, pavement repairs, and replacement of damaged sections. Subgrade is prepared to prevent settling, forms are set to match grade and alignment, and finishing produces the texture required by local standards. Each installation coordinates with drainage plans and site utilities so water flows correctly and no lines are damaged.

If your commercial or municipal project in the Illinois Valley needs curbs, sidewalks, or pavement work that meets accessibility and durability standards, reach out to Gillan Construction LLC to discuss your site plans.

How Concrete Walkways and Curbs Are Installed

Sidewalk and curb construction in the Illinois Valley starts with excavation to remove existing material or establish subgrade, followed by compaction and placement of aggregate base where needed. Forms are set to control width, thickness, and elevation, with slopes checked to meet ADA requirements of 1:12 or less for ramps. Concrete is placed, screeded, and finished with a broom texture for traction or a smooth finish for curbs.

Once the work is complete, you see level sidewalks with consistent slope, curbs that define parking areas and direct stormwater, and transitions that accommodate wheelchairs and strollers. Joints are placed at intervals that control cracking, and edges are tooled to resist chipping. The surface drains properly and shows no settlement or heaving.

Gillan Construction LLC follows municipal standards for joint spacing, thickness, and reinforcement. The service includes removal and disposal of old concrete when replacement is required. Pavement work does not include asphalt paving or seal coating, which are separate trades. Truncated domes and detectable warning surfaces are installed where code requires them.

What People Ask Before Pouring Sidewalks

Concrete walkways and curbs involve site grading, code compliance, and coordination with utilities, so clients usually ask about slope, thickness, and how long before the concrete can be used.

What thickness is required for commercial sidewalks?

Most municipal codes in the Illinois Valley require four inches for pedestrian sidewalks and six inches where occasional vehicle traffic may cross. Your site plan or public works department provides the specification.

How is ADA compliance verified for ramps and walkways?
Slopes are measured during construction to confirm they do not exceed 1:12 for ramps or 2 percent cross slope for walkways. Gillan Construction LLC uses a digital level or transit to verify grade before finishing.
Why do sidewalks crack even when newly installed?
Concrete naturally shrinks as it cures, which is why control joints are cut or formed at regular intervals. These joints guide cracks to predetermined locations rather than random patterns across the surface.
When can pedestrians walk on new concrete sidewalks?
You can typically allow foot traffic after 24 hours, but full strength develops over 28 days. Barricades or caution tape should remain in place until the surface is safe and fully cured.
What happens to existing utilities when sidewalks are replaced?
Utilities are located before excavation begins, and work is coordinated to avoid damage. If a utility conflict is found, the sidewalk alignment or depth may be adjusted, or the utility may need relocation.
