  • HEADWALLS

    Precast concrete headwalls are critical for giving structures such as bridges and drainage culverts lasting support to prevent damaging erosion. Without these dependable structures, erosion could eat into a culvert drainage outlet, which is damaging to the location’s infrastructure and environment. As erosion builds, massive flooding could arise.

    The same goes for the bridges we travel across everyday. Eroding dirt and rocks surrounding this structure eventually leads to massive breakdowns, resulting in bridge failure. That’s why Shea’s precast concrete headwalls are designed and manufactured with dependability as the top priority.

    Our precast concrete headwalls are manufactured in a variety of dimensions to meet the integrity of your project site. If you’re interested in a precast headwall, call Shea Concrete Products at (800) 696-SHEA.
