Accessible concrete, done to the details that matter
ADA-accessible routes live or die on small numbers: a ramp at 1:12 maximum slope, cross slopes no steeper than 1:48, firm and slip-resistant surfaces, and detectable warning surfaces where a walk meets a street. We pour accessible sidewalks and curb ramps to these standards every day, with the grade control and finishing discipline that make the difference between “close enough” and genuinely compliant.
What’s included
- Accessible routes with 36-inch minimum clear widths (wider where your plans require)
- Curb ramps at 1:12 maximum running slope with level landings top and bottom
- Truncated-dome detectable warning surfaces cast or set at ramp bottoms and transit interfaces
- Cross slopes held to 1:48 or flatter for stable wheelchair travel
- Slip-resistant broom finishes — never slick trowel finishes on accessible routes
- Coordination with your architect or civil engineer on grades, and with striping for accessible stalls and access aisles
Ideal use cases
New accessible routes for offices, retail centers, restaurants, medical buildings, churches, schools, and multifamily properties; retrofitting older properties whose ramps predate current standards; and repairing heaved or settled walks that have become non-compliant trip hazards. We also rebuild curb ramps during parking lot reconstruction so the whole site comes up to standard at once.
A note on compliance
We build to ADA Standards for Accessible Design and local requirements, but final compliance responsibility sits with the property owner and design team — we always recommend your architect or engineer confirm the design. What we guarantee is precise execution: slopes, widths, and warning surfaces built exactly to the plans and the standards, in freeze-thaw-rated concrete that holds those tolerances for years.
Built for Colorado’s climate
Heaved panels and settled ramps are how accessible routes fail in Colorado Springs — usually from water under the slab and expansive soils. We compact the base, control drainage, and use air-entrained concrete so slopes stay true through freeze-thaw cycles instead of drifting out of tolerance a few winters in.

The numbers in plain language: slopes, widths, and landings
Accessible design runs on a handful of measurements, and it helps owners understand what they’re looking at — even though your architect or engineer owns the final design. The headline number is the ramp slope: no steeper than 1 unit of rise to 12 units of run (about 8.3 percent). In practical terms, a 6-inch curb means a ramp at least 6 feet long; a 30-inch elevation change needs 30 feet of ramp, usually with a level landing breaking it up. That ratio surprises owners used to thinking of “a ramp” as a short wedge — real accessible ramps are long, gentle, and deliberate.
Cross slope — the sideways tilt of the walking surface — is capped even tighter, at 1:48 (about 2 percent). This is the number that fails most often in the field, because it’s hard to see: a sidewalk that looks flat can easily carry a 3-percent cross slope from sloppy grading, and a wheelchair user feels every bit of it as a constant downhill pull. We check cross slopes with a digital level during finishing, not after, because by the time concrete sets, the number is permanent.
Widths and landings complete the picture. Accessible routes need 36 inches of clear width minimum — wider wherever your plans call for it, and we always confirm against the drawings rather than assuming. Ramps need level landings at top and bottom (and at intervals on long runs) where a wheelchair can rest and turn; a landing that’s even slightly sloped becomes a place where a chair rolls when the user stops pushing. Getting these right is grade-control work: string lines, laser levels, and checking twice. “Close enough” is the most expensive phrase in accessible construction, because non-compliant work gets torn out.
Detectable warnings: what they are and where they go
Detectable warning surfaces — the truncated-dome pads you feel underfoot at curb ramps — alert visually impaired pedestrians that they’re entering vehicular traffic. They’re required at curb ramps, at transit stops, and at other street interfaces, and they come in two main types: cast-in-place (wet-set into fresh concrete) and surface-applied (bolted or glued onto existing concrete).
For new construction, we prefer cast-in-place or wet-set systems: the panel becomes part of the concrete, with no edge to catch snowplows or peel up. The domes must be aligned with the direction of travel and the panel must sit at the right position on the ramp — typically at the bottom, full width of the ramp — per your plans. Color contrast with the surrounding concrete matters for low-vision users; we coordinate the panel color with your design team rather than defaulting to whatever’s on the truck.
Surface-applied panels have their place in retrofits, where cutting out a ramp nose to wet-set a panel may not be practical. They’re a legitimate solution when properly installed on sound concrete — but they need the right adhesive, the right fasteners, and a flat substrate, or they become a maintenance item. During an estimate we’ll tell you which approach your situation actually warrants, because the cheapest panel installed badly is worse than no panel at all.
How accessible routes fail in Colorado Springs
Almost every non-compliant walk we rebuild failed the same way: the ground moved. Colorado Springs’ expansive clay soils swell with spring moisture and shrink in summer drought, and a sidewalk slab riding that cycle heaves at one end, settles at the other, and turns a compliant 1:48 cross slope into a 1:20 sled run. The second killer is water under the slab — poor drainage saturates the base, freeze-thaw does the rest, and within a few winters the panels are faulted enough to trip pedestrians and strand wheelchairs.
The prevention is unglamorous: compacted, well-drained base; concrete that resists freeze-thaw (air-entrained, adequate strength); joints that let panels move without faulting; and grades that never let water sit against or under the walk. We also pay attention to the gutter interface at curb ramps — the most failure-prone six inches on any site. If the gutter settles or the ramp nose lips up even a half inch, you’ve built a barrier where the accessible route meets the street. We form and verify that transition with particular care, because it’s where the whole system’s promise is kept or broken.
There’s also the slow failure: surface deterioration. A broom finish that’s too smooth polishes under foot traffic and becomes slick when wet; deicing salts chew up weak surfaces and create the spalled, uneven texture that catches cane tips and walker wheels. We finish accessible routes with a consistent, slip-resistant broom — never a slick trowel finish — and we specify concrete that holds its surface. An accessible route has to be accessible in year ten, not just at final inspection.
Retrofitting an existing property: the process
Most of our ADA work is retrofit: older properties whose walks and ramps predate current standards, or whose routes have drifted out of tolerance through settlement. The process starts with an assessment — we walk the property with you (and your architect or engineer, if one is engaged), measure existing slopes and widths, and identify every non-compliant segment: ramps too steep, cross slopes over tolerance, missing detectable warnings, walks too narrow, settled panels creating lips.
Then we prioritize. Full reconstruction of every walk is the gold standard, but budgets are real, so we help you sequence: the primary accessible route from accessible parking to the main entry comes first, then secondary routes, then cosmetic upgrades. Where existing concrete is sound but a panel has settled, mudjacking or grinding can sometimes restore tolerance without replacement — we’ll tell you honestly when a repair suffices and when replacement is the only fix that lasts.
Construction on an occupied property takes choreography. We phase the work so an accessible route remains open at all times — tearing out the only accessible entry ramp with no alternative is not an option — and we maintain temporary compliant routing with clear signage. Work areas get barricaded properly, not just coned; dust and noise are scheduled around your tenants’ or customers’ sensitive hours where possible. At completion, we document the built conditions — as-measured slopes and widths — so you have a record for your files. That documentation is worth keeping: if compliance is ever questioned, measured as-builts are your best evidence.
Working with your design team — and what we guarantee
Let’s be clear about roles, because this is where accessible projects go sideways. Your architect or civil engineer designs the accessible routes: they set the grades, locate the ramps, size the landings, and certify that the design meets the ADA Standards and local requirements. Final compliance responsibility sits with the property owner and the design team. Our role — and what we guarantee — is precise execution: we build exactly to the plans, hold the slopes and widths the design requires, and verify our work with measurements, not eyeballs.
Practically, that means we want the drawings before we price, we ask questions when grades don’t tie together (they sometimes don’t — a plan that works on paper can have a ramp landing floating six inches above the adjacent walk), and we flag conflicts in the field rather than building something we know is wrong. If you don’t have a design team and need a straightforward ramp or walk rebuilt to standards, we can work from established standard details — but for anything complex, we’ll recommend engaging an engineer, because the liability for the design belongs with a licensed professional.
We also coordinate the adjacent trades: the striping contractor placing accessible stall markings and access-aisle hatching (which must align with the built ramps, not the other way around), the signage installer, and anyone doing site lighting along the route. An accessible route is a system — concrete, markings, signage, lighting — and we make sure our part integrates with the rest.
What drives the cost
- Linear feet and ramp count. Straight sidewalk is efficient; every curb ramp is custom forming, careful grading, and a detectable warning panel.
- New versus retrofit. Retrofits add demolition, haul-off, phasing around occupants, and often grade corrections the original never had.
- Grade complexity. Flat sites are straightforward; sites needing ramps to negotiate real elevation changes involve longer runs, landings, and sometimes retaining.
- Base conditions. Expansive clay or poor drainage under the existing walks means base reconstruction, not just new concrete on old problems.
- Detectable warning systems. Panel type and quantity; wet-set on new work versus surface-applied on retrofits.
- Phasing and hours. Occupied properties needing phased work, temporary routing, or off-hours construction.
- Design and documentation. As-built measurements and coordination time with your design team.
Keeping the route compliant after construction
Compliance isn’t a one-time event — it’s a maintenance commitment, and it’s the part owners most often neglect. Put the accessible routes on your spring walkthrough checklist: check cross slopes and ramp slopes for movement (a digital level and five minutes per ramp), look for faulted joints and settled panels creating lips over a quarter inch, confirm detectable warning panels are intact and haven’t peeled or worn smooth, and verify that drainage still moves water off the route. Catching a heaved panel in year two is a grinding or mudjacking fix; ignoring it until year five is a reconstruction.
Winter operations matter too: snow removal crews should know where the detectable warnings and ramp noses are, because a steel plow blade catches panel edges and ramp lips. Use sand rather than piled deicing salts on accessible routes — salts damage the surface and the resulting spalling creates exactly the uneven texture the standards prohibit. And never let a “temporary” obstruction become permanent: the dumpster, the sandwich board, the snow pile that migrates onto the accessible route every winter. The most common compliance failure we see isn’t bad concrete — it’s good concrete blocked by bad habits.
