The iPlus® Composite laminate design theory optimally utilizes the structural reinforcing materials, reducing the CIPP wall thickness by about half. As with other CIPP products, the applied pipe loads are calculated according to the trenchless technology industry accepted standards, such as ASTM F1216.
iPlus® Composite is manufactured with a polypropylene coating on the inside pipe surface. This elastomeric flow surface coating increases the composite pipe’s smoothness, reduces the surface friction and provides an additional corrosion barrier for the sewer pipeline.
By combining innovative engineering technology with superior materials, Insituform provides a fully structural pipeline rehabilitation product with about half the wall thickness of conventional CIPP offerings.
