Maxibloc THVCBs provide H4a (Very High Containment) protection and are designed to deflect heavy goods vehicles from temporary and permanent bridge supports, other vulnerable structures and amongst other uses, provide effective temporary parapet protection.
The Maxibloc THVCB offers H4a containment, weighs roughly 4500kg and is a Highways England approved product.
A Maxibloc Surface-Mounted THVCB application provides a containment level of H4a and a working width of 1.81m (W6). The system is installed free-standing on the carriageway surface and the containment is achieved by installing a double thickness wall of intermediate barriers (V50) with staggered joints.
A Maxibloc Recessed THVCB installation provides a containment level of H4a and a working width of 625mm (W2). The intermediate (V50) concrete barriers are installed in a 200mm deep trench formed in the carriageway surface and the trench back-filled with concrete.
