City ADA Ramp Q&A's
An ADA-compliant ramp is designed according to federal standards to ensure accessibility for individuals with disabilities. This includes proper slope, width, handrails, landing size, and non-slip surfaces. We build ramps that fully meet ADA guidelines to provide safe, accessible entry for everyone.
The ADA requires a maximum slope of 1:12, meaning for every inch of vertical rise, the ramp must be at least 12 inches long. We ensure all ramps we construct meet or exceed this standard.
In addition to ramps, we also install tactile warning surfaces, proper grading, handrails, and smooth, slip-resistant pathways to help your site remain fully accessible.
We use the highest-quality materials when building our ADA Ramps. Our commitment to high-quality means that our ramps are built to last, and offer long-lasting functionality. Our suppliers are trusted to provide materials that will be durable, slip-resistant and weather resistant.

What is an ADA Ramp?
An ADA (Americans with Disabilities Act) ramp is a specifically designed access structure that meets federal guidelines to accommodate wheelchairs, walkers, and individuals with limited mobility. These ramps must meet strict requirements regarding slope (usually a 1:12 ratio), landings, width, handrails, and surface traction. At Keystone, we stay up to date with current ADA codes and local regulations to ensure full compliance and safety.
