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. 

  • MANHOLESAvailable 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)
