CIPP: Insituform Technologies
Insituform’s iPlus Infusion achieves a tight fitting pipe-within-a-pipe by implementing a pull-in installation method.
A resin-impregnated polyester and vinyl ester-filled tube, with an internal polypropylene coated felt layer, is pulled into the sewer line; the tube is inflated with air and then cured with low-pressure steam. iPlus Infusion is suitable for pipes 6-12-inch diameter and up to 700 feet in length. A small equipment footprint means iPlus can navigate steep slopes, making grade issues nonexistent. The internal polypropylene coating is designed to withstand steam temperatures and shares many of the properties of the polyethylene coating which provide resistance to solvents and microbes. 636.530.2825, www.insituform.com
