The Quick Culvert– Premium Range has been specifically developed to comply with all state road specifications and has been approved for use in state controlled projects. 

The joint has been specially designed to provide both a shear connection between units and a water-tight seal via a pre-lubricated gasket in the culvert joint. This same joint is utilized in between the end culverts and the headwalls with galvanized steel brackets to make sure the wingwall stays in place. A separate precast concrete cut-off wall is then bolted to the end of the apron of the headwall for erosion control. 

The design and manufacture of the units generally complies with the TMR Standard Specification MRTS24 Manufacture of Precast Concrete Culverts with some modifications to suit the arch rather than the box culvert shape.
