Patent abstract
A process and system is provided to allow rehabilitation of asbestos concrete (AC) pipe to remain in place while rendering the AC pipe harmless, in a manner that protects the ecosystem and saves huge amounts of money lost to bypass, digging, remediation and disposal. The method and system provide for encapsulation of the old AC pipe in place without any digging or disruption to the surrounding area. No dewatering is required, saving the costs required with dewatering. There is minimal disruption to the community's use of the piping system while completing the repair, as such repairs can be done on a manhole-to-manhole basis. Finally, there are no hazardous material disposal requirements, or the costs associated therewith.
