Units can be bent and shaped to create the exact configuration you need for your streets


SuperFlex Curbing can be used to create endless configurations such as traffic circles, road narrowing or widening, chicanes, bulb-outs, lane separation or road medians.

Cost effective

Rubber curbing is a long-lasting and removable for years of continuous use. Other solutions often require costly replacements while the Traffic Logix cushion units can simply be removed and reinstalled as necessary.

Highly visible

With a choice of yellow or white highway tape embedded into each unit, the rubber curbing is highly visible, even at night or in poor lighting conditions

Driver acceptance

Prefabricated units offer consistency at all locations, an important factor for motorist acceptance and ease of use. Unlike concrete and asphalt, rubber units maintain their shape over time and do not contract with heat or vehicle pressure.


The rubber curb units can be removed for road resurfacing, snow plows, or to test the products at numerous locations. Unlike asphalt and concrete which must be destroyed during removal, the rubber units can simply be removed and reinstalled.

Long lasting

The Superflex curbing is maintenance free and built to resist temperature fluctuations, inclement weather conditions, and ongoing vehicle traffic.

Two year warranty

Two year warranty on Superflex curbing components installed as per manufacturer's instructions.
