Box Culverts.

Box Culverts (RCB's) are a mainstay of Glacier Precast. We have the capacity to build multiple sizes and configurations. Spans from 4' to 20', and Rise from 4' to 10' are within our capability. RCB's are built to meet or exceed ASTM Specifications for Reinforced Monolithic Box Culvert Sections (ASTM - 1433-14 & ASTM 1577-14). Previous RCB projects include pedestrian tunnels, highway bridges, livestock crossings and Storm water structures. For areas where natural water flow needs to be maintained, we build open bottom arch culverts and foundations.
