NovaFormTM ‘Expand-in-Place’ PVC Liner is used in sewer and culvert rehabilitation. Extruded and coiled onto reels, the product is heated and conditioned using steam at the job site, then pulled into an existing sewer or culvert by mechanical means. The NovaForm Liner is plugged at both ends and expanded by introducing steam and then air, allowing it to form snuggly against the host pipe. As air is introduced, the pipe cools and hardens producing a fully functional pipe.
