Freestanding Temporary Concrete Barrier

ZoneBloc® is a revolutionary temporary concrete barrier system, designed to minimize impact to the traveling public while offering a supreme level of protection in freestanding applications. When tested to MASH TL-3, ZoneBloc® deflected only 44″ and a working width of 63″.

With a base width of only 12″, the compact design is effective on projects where space is restricted. Its 40 ft. standard unit is optimal for deployment and accelerates the installation process, when compared to traditional concrete barriers.

The narrow footprint results in a lightweight configuration, which allows 280 feet to be hauled on one flatbed truck.

The unique coupling system guarantees a safe and quick installation and large contact areas with integrated rubber pads result in a low surface pressure and protect the road surface.


Compact lightweight design (system width 12”) with integrated coupling (no loose parts) allows for 280′ to be hauled on one truck
High installation speed: easy and quick installation, relocation, and removal
Rubber pads in contact areas for protection of road surface
Narrow footprint and low deflection distance of only 44” results in compact working width of 63”
