Gradient grooves on the top surface improve water drainage while creating turbulence that produces warning noise as vehicles leave the lane.
Suspended metallic screens reduce neck compression forces and prevent entanglement during collisions.
Offset floor panels employ extended side wall loops to create rigid, tilt-proof units that prevent structural instability in large-area installations.
Nested skirted booms extend below hoods to filter pollutants, preventing drawdown under the barrier during high flow events.
Segmented slot tubes enable local replacement of damaged sections without full system disassembly, preventing water leakage.
Expanded polypropylene foam layer reduces excavation depth and carbon emissions while maintaining pitch stability.
Nested wire baskets separate sediment from storm water, reducing installation complexity while maintaining structural strength.
