Manhole Bases, Risers, Cones, and Lids

Precast concrete manholes and accessories manufactured for the state of Idaho.

CXT Precast Concrete Nampa Idaho Manholes.

Manholes are often used as an access point for an underground public utility, allowing inspection, maintenance, and system upgrades.

Precast concrete sets the standard for utility holes. A manhole will typically have a cast iron ring and cover on top allowing for access and provides durability to last through weather and traffic for decades before requiring replacement. Manholes can be cored and channeled for your project specifications.

Benefits:

  • Superior strength, durability, and hydraulics

  • Increased strength over time

  • Long-term maintenance-free conveyance of sewer and stormwater

  • Resistance to buoyant forces better than all other manhole materials
