Roadwork requires more than just round manhole adjustments. We fabricate heavy-duty steel and cast iron rectangular risers designed specifically to raise storm grates and curb inlets to final grade.
Fully enclosed or D-shape profiles for curb abutments.
Engineered for flat grate elevation in highway shoulders.
Roads are rarely precision flat. When resurfacing requires accommodating road crown or grade changes, standard flat risers cause manhole covers to sit unevenly. Our custom-tapered rings ensure a precision flush fit.
Custom slopes available to meet project-specific design requirements.
Ensures covers sit flush, preventing plow blade snags.
Ensure full ADA compliance and pedestrian safety with our high-durability tactile warning surfaces. Designed for seamless integration into municipal curb ramps, street crossings, and transit platforms.
