Concrete accessible entry approach showing compliant slope and finished surface quality

The Result

Accessible Routes That Meet Code and Work in Practice

ADA-compliant concrete is about more than the ramp — it's the approach, the landing, the slope transition, and the truncated dome placement that together make an accessible route genuinely usable. Getting the slope numbers and landing dimensions right the first time is simpler than retrofitting work that was done close-but-not-quite.

Overview

What ADA Concrete Work Covers

Projects include curb cuts and ramps at intersections and parking lots, accessible building entries and thresholds, truncated dome detectable warning installation, commercial walkways meeting slope requirements, and accessible parking area concrete. Both new installations and upgrades to non-compliant existing concrete are common scopes.

Common Reasons

Commercial Property Compliance

Bringing existing commercial properties into ADA compliance — particularly curb ramps, building entries, and parking access routes.

New Commercial Construction

Accessible route concrete as part of new commercial building projects — coordinated with site work, parking, and building entry design.

Parking Lot Accessibility

Accessible parking spaces, access aisles, and routes from parking to the building entrance.

Building Entry Ramps

Ramp additions, threshold corrections, and entry approach re-grading to create accessible building entries.

Municipal Sidewalk Curb Ramps

Curb ramp installation at intersections as part of public right-of-way improvements or required compliance work.

Technical Standards

What Matters on ADA Concrete Projects

Running Slope Requirements

Ramps have a maximum 8.33% running slope (1:12 ratio). Steeper slopes are non-compliant. Landings at top and bottom must be essentially level (max 2% slope in any direction).

Cross-Slope on Accessible Routes

Accessible walkways can't exceed 2% cross-slope. Steeper cross-slopes make wheelchair navigation difficult and are non-compliant.

Truncated Dome Specifications

Detectable warning surfaces (truncated domes) are required at curb ramps and hazardous vehicle crossings. Dome dimensions, spacing, and color contrast are ADA-specified.

Landing Dimensions

Landings at the top and bottom of ramps, and at door entries, must meet minimum dimension requirements (typically 60 inches × 60 inches) for wheelchair maneuvering.

Drainage Without Creating Slope Violations

ADA concrete still needs to drain. The challenge is routing drainage while keeping the surface within the maximum allowable cross-slope.

Raytown & Southeast KC

Local Conditions That Affect This Work

KC's freeze-thaw cycling makes ADA ramp concrete vulnerable to damage because water collects at ramp bases and in landing areas. Proper drainage design — sloping away from the ramp transition while maintaining compliant cross-slope — reduces freeze-thaw damage and prevents ice formation that makes accessible routes hazardous in winter.

From First Call to Final Walkthrough

Request Your Estimate

Call or submit the form. We'll schedule a site visit at your property — no phone quotes for work we haven't seen.

Site Review and Quote

We assess scope, site conditions, and measurements in person, then provide a written quote.

Prep, Form, and Pour

We handle demo if needed, subgrade preparation, forming, and the pour on an agreed schedule.

Finish and Walkthrough

We finish to spec, apply curing compound, and walk you through care and timeline before leaving the site.

Note for this service

We verify slope compliance before finalizing forms — max 8.33% ramp run, max 2% cross-slope on landings and accessible routes. Getting this right before the pour avoids costly reconstruction.

Common Questions

ADA Concrete FAQ

What slope is required for an ADA ramp?

Maximum 8.33% (1:12 ratio) for the ramp run. Landings at the top and bottom must be no steeper than 2% in any direction. Steeper slopes are non-compliant under ADA Standards for Accessible Design.

What are truncated domes and when are they required?

Truncated domes — also called detectable warning surfaces — are the raised bumpy surfaces at curb ramps. They're required at curb ramps where pedestrian routes meet vehicle areas. Dome pattern, spacing, and color contrast requirements are set by ADA standards.

Do ADA upgrades require permits?

Commercial ADA work typically requires building permits. Curb cuts in the public right-of-way require permits from the municipality. We'll identify permit requirements for your project during the estimate.

Can you do ADA ramps at a residential property?

Yes. Residential accessibility adaptations — ramps at front entries, accessible routes from driveway to door — are within scope. These follow ADA design principles even if they're not technically required under the ADA for private residences.

How do I know if my existing ramps are compliant?

The most common non-compliance issues are ramps that are too steep (over 8.33%), landings that are too small, truncated domes that are missing or incorrect, and cross-slopes that exceed 2%. We assess what we observe during the site visit.
