Rehabilitation Manholes

Under certain circumstances total structural degradation of pre-cast manholes can occur in less than 5 years. Instead of continuing to patch perpetually corroding concrete, simply reline the existing structure with a CSI fiberglass rehabilitation manhole.

Rehabilitation Manholes can be installed within existing brick or precast manholes to provide a long-term and cost-effective solution to manhole rehab. CSI rehab manholes are manufactured using the same composite and process as standard manholes so they inherently resist the effects of hydrogen sulfide while withstanding HS-20 traffic loads. They meet or exceed the requirements of ASTM D-3753 Glass Fiber-Reinforced Polyester Manholes.

Because of the convenient slide-in method of installation, CSI rehab manholes do not require unearthing older corroding manholes saving you time and money. These newly installed manholes will still carry a 20-year warranty just like standard fiberglass manholes from CSI.
