DESIGN DETAILS
Precast Arch Units are cast off site and typically installed in a
single day. Backfill can be placed the very next day.
Precast Headwalls and Wingwalls are set with the same crane to complete the installation.
The structure can be set on strip footings, pedestal wall
foundations, slab foundations or piles.
