Box Culvert

What is the use of box culvert?

Precast box culvert has long been recognized as a way to speed up the construction of DOT, civil, and commercial projects. Recently, this advantage has been enhanced with the introduction of the Complete Precast Box Culvert System by Permatile Concrete Products Company.

How is a box culvert constructed?

Permatile manufactures precast box culvert in single or monolithic multiple cell sections. With the advent of new technology, double and triple box culverts can now be manufactured in one monolithic unit with laying lengths up to eight feet, thereby eliminating the cost and time-intensive installation of multiple lines of single-cell boxes. Permatile’s precast box culverts may also be skewed in most cases to meet the project requirements.
