Culvert Forms: Box

The traditional box culvert system consists of a modular, panelized form system mounted to a telescoping strongback that enables size changes in both the vertical and horizontal axes.

The longitudinal strongback just above the invert provides a location for both raising the system into the casting position and attaching casters for moving.

Steamboat jacks are integrated to facilitate stripping and resetting.

Capacities are 1,200 PSF with a 4' x 4' tie pattern.
