End Sections & Wingwalls

Precast end sections for box culverts and pipe provide a reliable, efficient solution for drainage and water management systems. These durable structures are engineered for easy installation and long-term stability, ensuring seamless integration with box culverts and pipes. Their high-quality precast construction guarantees consistent performance and low maintenance.

Precast Options to Fit Your Design

While it is generally acceptable to end a pipe or box culvert run with a plain straight barrel piece, most owners and designers prefer a tapered end section at each end of the structure to contour to the surrounding grade. McCann Concrete offers numerous options that cover any range of design cases and most end section types can be manufactured for pipe culverts or box culverts including IDOT standard box culvert end section, parallel wall end section, flared end section, wingwalls, headwalls, and toewalls.

Using a combination of our precast box culvert and end treatments, we can design and manufacture a single-sourced, 100% precast, culvert structure for most design cases.
