Oldcastle Precast manhole bases can now be produced with factory-cast channels and boot connectors. We stock most angles. This provides an economic advantage to field poured channels.  Oldcastle Precast sewer manholes are manufactured to ASTM C 478 standards.

Provide us with a copy of the plan showing elevations and a sales representative using our state of the art Stack-It estimating system can provide you a job submittal along with the most cost effective stacking configuration.

Manholes are available with:

  • Factory-cast channels with boot connectors
  • Access doors
  • Steps
  • Risers
  • Cones
  • Custom holes
