Plastic Crash Cushion Barriers are water-fillable modular safety barriers designed for road lane separation, construction-zone delineation, and temporary traffic management at road works, events, and infrastructure projects.
Manufactured from high-density polyethylene (HDPE), the barriers are filled with water on site to provide vehicle-containment mass without the transportation weight associated with concrete alternatives. Individual units interlock to create continuous barrier runs of the required length.
Key Specifications:
- High-density polyethylene (HDPE) construction
- Water-fillable design
- Water capacity: 700-1000 litres per unit, depending on model
- Standard unit dimensions compatible with NHA work-zone barrier specifications
- Interlocking connectors for continuous barrier runs
- Forklift and crane lifting points for mechanical handling
- Available in orange and white
- Vehicle containment rated for passenger-vehicle impact speeds appropriate for construction-zone applications
- Type 1 and Type 2 profile options for different containment requirements
