Bristol – Flow Stopping 6″ Main
The 6” low pressure main in the High Street of Paulton, near Bristol, was being replaced with a new PE pipe but one section needed to be kept live as it was feeding three homes.
The National Grid Transco team used a FOAMBAG™ kit to flow stop the section to be abandoned before cutting out and tying the new PE to the live section.
One-way traffic was maintained in the narrow, busy street. Had a conventional flow stopping bag been used, the large excavation required would have closed the road completely.
