The full line

Every precast structure on the plan sheet

Pipe is rarely the only precast item on a drainage job. We supply the structures that go with it, so the whole package comes from one supplier on one ticket.

Round reinforced concrete pipe

The most readily available and most cost-efficient of the concrete pipe shapes. Storm drain, culvert and sanitary sewer runs.

ASTM C76 · AASHTO M170

Reinforced concrete arch pipe

For low-cover and restricted-headroom installations where a round pipe will not fit the section.

ASTM C506

Elliptical pipe

Horizontal or vertical elliptical sections where cover is tight or hydraulic shape matters.

ASTM C507

Precast box culverts

For depth or height restrictions that demand wide, shallow conduits, and where a circular or elliptical pipe cannot carry the flow.

ASTM C1577 · AASHTO M273

Three-sided & bridge systems

Precast three-sided structures and modular bridge systems that build a crossing in a fraction of the time cast-in-place takes.

ASTM C1504

Precast manholes

Sanitary and storm manholes for access, observation and junctions, with precast invert channels available.

ASTM C478 · AASHTO M199

Inlets & catch basins

Curb inlets, drop inlets and catch basins that collect surface runoff from roadways, parking lots and other surfaces.

ASTM C913

End sections & flared ends

Terminate inlets and outlets, control the hydraulics and help prevent erosion by diverting flow.

Per state DOT detail

Headwalls & wingwalls

Finish and secure the ends of pipe, box culverts and bridge sections, designed to work with the conduit.

Per project detail

Joints & gaskets

Rubber-gasketed joints for circular concrete sewer and culvert pipe, and resilient connectors at manhole walls.

ASTM C443 · C923

Specialty & custom precast

Skews, bevels, tees, junction boxes and one-off structures cast to your drawing when a catalog piece will not do.
