Mining and Aggregate Tunnels
CON/SPAN and BEBO structures can be adapted for use in tunnel applications or improving mine entrances. The arch shape is also ideal for supporting aggregate piles and can be designed to accommodate site specific openings and equipment requirements.

Pipe and Utility Crossings
A precast arch system is ideal for spanning and protecting active utility lines and pipes beneath roads that carry heavy loads. Precast footings can be provided for a complete precast system that can be set in a single day.
Grade Separations
Precast structures are commonly used for grade separations to eliminate dangerous intersections between off-highway haul trucks, railroads and public roads. These systems are strong enough to carry massive off-highway and railroad loads and are available in shapes to accommodate critical clearance boxes.
