Manholes (Round)
Precast manholes are an essential component for most underground utility projects, providing either an access or transition points. Foley Products Company has built our business around providing a quality precast manhole combined with superior service. We keep significant inventory of standard components to provide the fastest service in our market.
Available in sizes from 48” to 144” diameter.- Precast Storm or Sewer Inverts
- Standard and Custom Tops
- Custom Hole Penetrations or Booted Connections
- Knock-out Panels in Select Markets

Our precast manholes are made to national standards in a certified factory using either drycast or wetcast production methods. Either method produces a quality product meeting your projects specifications.
Drycast: Utilizes a low water to cement ratio and zero slump to accommodate production methods (typically for risers and top sections)
Wetcast: Conventional concrete; however, FPC uses self-consolidating concrete to improve production efficiencies and quality (typically for base sections)
