New concrete stairs and sidewalks with ADA-compliant ramps
ADA-compliant concrete ramps, curb cuts, and accessible surfaces in Oklahoma City — fast response to violations and proactive upgrades. (405) 458-4805.
The Americans with Disabilities Act requires accessible concrete surfaces at every commercial property — parking lots, entrances, sidewalks, and curb transitions. Non-compliant properties face fines, lawsuits, and liability exposure. FDZ builds and repairs ADA-compliant concrete ramps, curb cuts, and accessible surfaces throughout the OKC metro. Whether you received a violation notice, failed an inspection, or are proactively upgrading your property, we provide fast, code-compliant installation with documentation you can present to inspectors and tenants.
Commercial properties along Penn Ave, May Ave, NW Expressway, and in downtown OKC are actively inspected for ADA compliance. Newly permitted projects require ADA-compliant accessible routes as a condition of certificate of occupancy. OKC's expansive clay also creates a secondary challenge: accessible surfaces that were compliant when poured can become non-compliant as clay movement creates cross-slopes exceeding the 2% ADA limit.
New curb ramps at parking lot transitions — saw-cut existing curb, proper 1:12 slope, detectable warning surface, and compliant landing at top and bottom.
Freestanding ramps at building entrances and loading areas — width, slope, landing, and handrail coordination per ADA standards.
Accessible parking spaces, access aisles, and connecting routes — layout, slope, marking, and signage coordination.
Truncated dome panels or cast-in-place dome concrete at curb ramp transitions — required at all curb ramps per ADA and OKC code.
Fast response to cited violations with documentation package — photos, measurements, and completion certificate for the city or ADA inspector.
ADA concrete compliance comes down to four things: slope, surface texture, width, and detectable warnings. Get any of these wrong and the surface fails compliance regardless of how well the concrete was poured.
Maximum ramp slope: 1:12 ratio — no steeper than 8.33% (one inch of rise per twelve inches of run). Maximum cross-slope on accessible routes and landings: 2% (1:50). Minimum ramp width: 60 inches where handrails are required. Surface must be stable, firm, and slip-resistant — broom finish meets this requirement. Detectable warning surfaces (truncated domes) required at all curb ramp transitions.
| ADA Concrete Spec | Requirement |
|---|---|
| Maximum ramp slope | 1:12 (8.33%) |
| Maximum cross-slope | 2% (1:50) |

| Minimum accessible route width | 36" |
| Landing slope (all directions) | 2% max |
| Detectable warnings | Required at all curb ramps |
| Surface texture | Stable, firm, slip-resistant |
Every ADA project is site-specific — pricing depends on the number of ramps, existing concrete conditions, and whether permits are required.
