ADA ramps and curb cuts are accessibility code, not optional design. Every slope, every cross-fall, every detectable warning panel has a defined spec, and inspection compares the as-built work against it. Oshawa Concrete pours ADA ramps and curb cuts to those specs, ties them into adjacent commercial sidewalks and curb and gutter, and documents compliance for the inspector. Every project starts with a free written estimate.
ADA accessibility specs are clear about what a ramp or curb cut must do: a maximum running slope, a maximum cross-slope, a minimum width, detectable warnings (the truncated dome panels) at every flush transition between pedestrian and vehicular surfaces, and level landings at the top and bottom of every ramp run. Hit those specs and the work passes; miss any one of them and it fails inspection.
We design and pour every ADA ramp and curb cut to those specs, with the detectable warning panels embedded properly, the cross-slope verified during the pour rather than estimated after, and the landings sized correctly for the transition. Where the existing site has an out-of-spec ramp or curb cut, we replace it to current code.
We verify the applicable ADA spec for the project (federal, provincial, or local accessibility code), confirm the slope, cross-slope, width and landing requirements, and identify where detectable warnings are required.
Excavate ramp to elevation
The ramp footprint is excavated to subgrade, with the start and end elevations confirmed so the running slope hits the ADA max, and the cross-slope footprint is graded into the base.
Form, embed warnings
Forms are set with the engineered slope and cross-slope, reinforcement placed, detectable warning panels positioned in the form footprint where required, and the ramp transition to adjacent walks or curbs is detailed flush.
Pour, verify, document
Concrete is placed and finished, slope and cross-slope are verified with a level before cure, the detectable warning panels are confirmed in position, and the as-built dimensions are documented for inspection.
Where ADA work fails
Slope Is What Most ADA Work Misses
The most common ADA failure we are called to remediate is slope, either the running slope is too steep (the ramp came out at higher than the max angle) or the cross-slope drains across the ramp instead of off the side. Both fail inspection and both require demolition and re-pour to fix; you cannot adjust slope on cured concrete — which is why commercial concrete ADA work has to be right the first time.
We verify slope during the pour, not after. A level and a story-pole on every section catch slope errors while the concrete is still workable. The result is a ramp that passes inspection on the first walk-through. Coordinate with adjacent commercial sidewalks so the ramp lands flush at both ends.
Slope specs, detectable warnings, landings, and where ADA work is required.
The current ADA running-slope maximum is defined in the accessibility code; we follow the specific code version applicable to your project (federal, provincial, local). The cross-slope maximum is also specified separately and is just as critical.
Truncated dome panels (typically yellow, cast into the concrete or surface-mounted) at every flush transition between pedestrian and vehicular surfaces. They are tactile cues for the visually impaired. They are required at curb cuts, ramp bottoms at parking lots, and similar transitions.
Yes, ADA requires a level landing at the top and bottom of every ramp run, sized to the spec for that ramp's use. The landing has to be flat in both directions (running and cross-slope) within the ADA tolerance.
Modification rarely works because slope cannot be changed on cured concrete. Most non-compliant ramps need full replacement to bring them to current code; the quote will say which case yours is.
Most public-accessible commercial properties do, especially new construction and any renovation that triggers accessibility review. The exact scope depends on the property, the renovation work, and the local accessibility code; we coordinate with the accessibility consultant on every project.
They replaced four non-compliant curb cuts across our retail center. Each one to current ADA spec, detectable warnings cast in, accessibility consultant passed all four first walk-through.

Slope was verified during the pour, not after. They had a level out on every section. The inspector specifically commented on how clean the as-built dimensions were.

Multiple ramp installations during off-hours so the mall stayed open. Coordinated with adjacent sidewalk pours, detectable warnings flush, ADA inspector signed off without a single revision.

ADA ramps at every entrance to our medical building. They knew the accessibility code cold, no improvisation, no surprises at inspection. Compliance was their first concern, not their last.
