Description
1.1 This practice covers requirements and test methods for installation of a semi-structural polyethylene (PE) and encapsulated cement mortar formed-in-place lining system (FIPLS) intended for the rehabilitation of water pipelines from 4 in. to 12 in. This renewal process involves installing a folded PE liner with multiple hooks on the outside face into an existing water pipeline then pumping cement mortar into the annular space and progressively reforming the liner against the original pipe wall by means of forcing a reforming device through the pipeline.
