Commercial Concrete
ADA Concrete in Smithville and the North KC Metro
ADA-compliant concrete covers the ramps, curb cuts, accessible walkways, and entry approaches that provide required access to commercial properties. Smithville Concrete Services pours ADA concrete to the dimensional and surface requirements that compliance demands — slope, cross-slope, surface texture, and landing configuration.

What You Get
Accessible Entries and Paths That Meet the Requirements
ADA concrete work provides compliant access that serves real users — customers, employees, and visitors with mobility limitations — while protecting commercial property owners from accessibility deficiencies. Done correctly, it integrates into the property rather than looking like a retrofit.
- ADA ramps at curb cuts and sidewalk transitions
- Accessible entry approaches and door landings
- Accessible parking stall approach walks
- Detectable warning surfaces (truncated dome panels)
- Compliant walkway width and cross-slope correction
- Coordination with existing paving and curb systems
Common Projects
When Homeowners and Businesses Call Us for ADA Concrete
Commercial property accessibility update
A commercial property that needs curb cuts, ramp approaches, or accessible routes to meet ADA requirements for customers and employees.
New commercial construction access
A new construction project that needs ADA-compliant site access integrated from the start — curb ramps, parking approaches, entry walks.
Parking lot accessibility improvements
Adding or upgrading accessible parking stalls and their approach paths to meet current requirements.
Building permit or inspection requirement
A remodel, addition, or change of use that triggers accessibility requirements under local or federal building code.
Tenant improvement
A commercial tenant improvement that requires upgraded exterior access as part of the permit scope.
Technical Standards
What Makes a Well-Installed ADA Concrete
Ramp slope: maximum 1:12 (8.33%)
The running slope of an ADA ramp cannot exceed 1:12 — one inch of rise for every 12 inches of horizontal run. Steeper ramps do not meet the requirement regardless of other design features.
Cross-slope: maximum 2% (1:50)
The surface perpendicular to the direction of travel cannot exceed 2 percent. Cross-slope over this threshold causes wheelchair instability and fails the technical requirement.
Landing dimensions
At the top and bottom of every ramp, and at doors, landings must be at least 5 feet by 5 feet to allow wheelchair turning radius. This is a common deficiency in retrofit work when existing site constraints are tight.
Detectable warning surfaces
Truncated dome warning panels are required at the base of curb ramps where the accessible route meets the street or vehicle area. These are tactile indicators for visually impaired users.
Accessible route continuity
An accessible route must connect from accessible parking spaces to building entries without requiring travel behind parked vehicles or across curbs. This sometimes requires rethinking the overall site path before designing the concrete.
Local Context
ADA Concrete in Smithville and the North KC Metro
Frost Heave at Ramps
ADA ramps that heave from frost action present both a compliance problem and a safety issue. Proper footing depth and drainage around ramp bases are important in the KC climate.
Deicer and Detectable Warning Surfaces
Detectable warning dome panels made of concrete are durable and deicer-resistant. Plastic retrofit panels degrade faster in freeze-thaw climates — concrete-integral dome panels are the more durable choice for KC winters.
