* Depends on angle of shear
Our Heavy Duty crate is suitable for most situations subject to vehicular use from car parks right up to major roads. With only 2.5 crates to a m3 it is fast to install and the use of the unique inners and outers allow the water to flow in three dimensions without restriction whilst still maintaining the strength of the closed system. The open structure allows multiple routes for maintenance and inspection.
