Commercial trip-hazard exposure under the ADA Standards for Accessible Design §302 (Floor or Ground Surfaces) is one of the most common accessibility violations cited on multifamily, retail, hospitality, and office properties. It is also one of the easiest to fix — when you have the right tool. Foam injection lifts a settled slab back to flush with its neighbor without saw-cutting, demolition, or days of closure. Most jobs are resolved in 1–2 hours.
Residential or HOA sidewalk lift without ADA-claim exposure? See residential and HOA sidewalk leveling — same crew, simpler scope, no compliance documentation needed.
The ADA threshold (2010 Standards §302.2)
- Up to 1/4" — permitted with no treatment
- 1/4" to 1/2" — must be beveled at 1:2 slope
- Over 1/2" — must be ramped (1:12 max slope) or removed
In practice, anything over 1/4" with a sharp edge is non-compliant. A documented complaint or claim moves the timeline from "should be addressed" to "must be addressed."
Where we lift ADA hazards most
- Public sidewalks and walkways on private commercial property
- Retail and restaurant entrances, threshold approaches
- Apartment, condo, and HOA pedestrian paths
- Hotel and resort walkways and entry plazas
- Office park and corporate campus exterior paths
- Medical, dental, and clinic exterior accessibility
How we resolve trip hazards
- We measure offsets with calipers — verifying current condition pre-repair
- We drill 5/8" injection points through the settled slab
- We inject polyurethane foam to lift the slab to flush with its neighbor
- Laser-level the lift — final verification with calipers
- Patch the holes flush and surface-treat for matching
- Walk on it in 15–30 minutes — pedestrian flow restored
Documentation we provide
On every ADA job, we provide:
- Pre-repair photos with measurement reference
- Post-repair photos with verified offset measurement
- Written scope-of-work and date/time of completion
- Certificate of Insurance on request, in advance
We do not provide legal compliance certifications (your accessibility consultant or counsel handles that), but our documentation supports their review.
