The XL range of concrete headwalls has been introduced to cater for large diameter pipe culverts where heavier loads are experienced such as within highway boundaries and rail applications. These precast concrete headwalls have a design life of 120 years and an exposure class of XD3.

The range currently consists of the XLS18 and XLS25 headwalls which can accommodate internal diameters of up to 1200mm and 1800mm concrete pipe respectively. The wingwalls can be extended using "L" walls if required.
