Jensen Precast is one of the largest producers of reinforced precast concrete box culvert products in the industry.  With 3 styles of box culvert, and manufacturing plants located throughout the Western United States, both contractor and specifier have limitless options to fulfill project requirements. All of our Box Culvert structures are designed by a staff of Professional Civil & Structural Engineers certified by the NPCA and adhere to AASHTO, ASTM and ACI guidelines.
In January 2015, ASTM announced the approval of a standard for precast segmental box culverts. ASTM C1786 is the first ASTM standard specifically covering precast segmental box culverts. The Jensen Precast Type 1 and Type 2 Segmental Box Culverts (also known as Cantilever Wall Box Culverts) are included in this group of products.
