Description Absolute Concrete have produced rural stock underpasses usually ranging from 2.0×2.0m units up to 4.0×3.0m units with fill heights between 0 and 3m including units used under railways, however units to other specific designs or standards can also be accommodated. Standard units features such things as duct holes for site stressing or coupling via tie rods. Keyways for interlocking between boxes. We can also cast in starter bars to tie into wingwalls or apron slabs and precast wingwalls and headwalls can be added. When precast concrete stock underpasses are used they have been found to reduce animal stress and road crossing maintenance and increase safety for staff, stock and the road user. Design Our units are all designed by an independent structural engineer in accordance with the Transit New Zealand Specifications and are suitable for HN:HO-72 loading and as such they will meet all the requirements for use under roads and state highways. Prices are quoted on an individual basis based on quantities and specific requirements. We have our own Hiab trucks and can deliver according to your location
