Heavy-duty precast concrete barriers in 2, 3 and 4 metre lengths — made in Victoria, delivered across the east coast, with painting, logos, connection plates and hoarding options.

Modcast precast concrete barriers are manufactured in our North Wangaratta factory for worksite separation, site perimeters, car parks, events and access control. Each unit is cast in steel moulds from high-strength reinforced concrete, with cast-in lifting inserts on top and forklift pockets underneath for fast placement by crane, Hiab, forklift or excavator.
All three lengths share the same 620 mm wide, 830 mm high profile, so 2 m, 3 m and 4 m units can be mixed in one continuous run: 2 m for tight sites and corners, 3 m as the general-purpose unit, and 4 m for long runs with fewer joints and lifts.
| Unit | Length | Width | Height | Volume | Mass |
|---|---|---|---|---|---|
| 2 m barrier | 2,000 mm | 620 mm | 830 mm | 0.64 m³ | 1,650 kg |
| 3 m barrier | 3,000 mm | 620 mm | 830 mm | 0.96 m³ | 2,450 kg |
| 4 m barrier | 4,000 mm | 620 mm | 830 mm | 1.28 m³ | 3,300 kg |
Dimensions are indicative. Refer to Modcast shop drawings for construction details and confirmed lifting weights.

Need something different? Because we make our own moulds, we can modify lengths, add cast-in fixings or produce custom blocks to suit your project.
Modcast barriers are intended for private sites, worksites separated from live traffic, car parks, events, laydown areas and perimeter delineation. They are not an AS/NZS 3845 accepted road safety barrier system and are not crash-tested or rated for hostile vehicle mitigation. If your project needs an accepted or rated system, talk to us and we'll point you in the right direction.
