Manholes

Precast Concrete Manholes

Precast concrete manholes from Seminole Precast Manufacturing, Inc. (SPMI) offer superior quality, safety and ease of installation. Our precast manholes and related products can be used for the following applications:

  • Manholes are precast concrete underground structures used in sanitary and storm applications to provide access for monitoring flow, connecting various piping systems together and changing flow direction

  • Inlet structures include catch basins, drop inlets, and curb inlets and are designed to collect surface runoff and transfer it to underground storm water systems

  • Headwalls are above-ground structures that improve flow both upstream and downstream of the pipe

  • Flexible design

  • Can be designed to fit existing utilities

  • Ultimate strength through quality-controlled plant production 

  • Watertight construction
