California ADA Concrete Specialists
Concrete is one of the most technically demanding components of ADA compliance. Slopes, cross-slopes, transitions, and landing areas must meet extremely tight tolerances under federal ADA standards and California Title 24 requirements. A deviation as small as 1/16 inch over one foot can determine whether a surface passes or fails inspection.
Protrk® Construction specializes exclusively in ADA-focused concrete construction. From sidewalks and curb ramps to parking lots and accessible routes, every surface is engineered to meet strict 2% cross-slope maximums and code-driven directional slope requirements.
1 Precision Slope & Surface Control
ADA compliant concrete is engineered, not simply poured. Accessible parking stalls, wheelchair ramps, curb ramps, and sloped walkways must comply with strict cross-slope and directional slope tolerances.
- Maximum 2% cross slope in critical areas
- Directional slopes under 5% for accessible walks
- Ramp slopes under 8.33% where permitted
- Measured forming and finish verification
We utilize detailed measurements and controlled forming methods to ensure finished surfaces remain compliant after curing. Because concrete maintains shape more reliably than asphalt, it is the preferred surface for ADA-critical zones. Our installations are built to withstand inspection and long-term operational use without settlement-related failures.
2 Common ADA Concrete Failure Hotspots
Many CASp inspections identify failures in exterior concrete caused by improper slope calculations, inconsistent transitions, or contractor inexperience.
- Parking stall geometry errors
- Curb ramp flare slope violations
- Sidewalk cross-slope inconsistencies
- Door landing clearance deficiencies
Approximately 25% of Protrk® concrete work involves correcting previously installed non-compliant surfaces. Redoing failed work is costly and disruptive. Our ADA-only specialization eliminates guesswork and ensures surfaces are constructed correctly the first time.
3 ADA Grind-Fill-Color Hybrid Method
When full demolition is not required, Protrk® offers a specialized Grind-Fill-Color hybrid correction method to address localized slope deviations without extended closures.
- Localized slope correction
- Reduced operational disruption
- Targeted compliance restoration
- Cost-effective remediation when feasible
This method is ideal for high-traffic entry zones and limited correction areas where complete removal would create unnecessary downtime. The approach maintains measurable compliance while preserving surrounding structural integrity.
4 Truncated Domes & Detectable Warnings
Federal and California regulations require detectable warning surfaces — commonly known as truncated domes — at pedestrian-to-vehicular transition points. These tactile systems alert visually impaired individuals when entering shared vehicle zones.
- California-compliant truncated dome installation
- Proper alignment and embedment
- Integration with surrounding slope geometry
- Durable long-term performance
Protrk® installs code-aligned truncated domes engineered for durability and measurable compliance. Proper placement and integration with adjacent slopes are critical to maintaining full accessibility alignment.
