Engineering/Design

Inliner tubes are made of a felt material saturated with resin and coated with a waterproof polyethylene layer. Polyester needled felt and polyester resin systems are standard, but vinylester resins and a variety of other materials may be used when applicable. Inliner has patented two innovative, unique technologies to offer customers a vastly superior CIPP product: ResinGuard™ and StretchGuard™.

• ResinGuard™ protects the resin–saturated inner felt from washout, dragoff, squeezeout, and contamination during installation. For the end user this provides superior consistency of thickness and enhanced strength.
  
  
• StretchGuard™ prevents distortion of the tube as it is pulled or inverted into a pipe. Inliner determines the required thickness of the liner using ASTM 1216, the industry standard for cured–in–place piping. StretchGuard ensures that these standards are protected during installation. This patented technology is a key Inliner benefit. Our unique product design eliminates leaks, promotes safety, reduces risks, and protects the environment – with a 50–year service life.

Inliner has invested heavily in its manufacturing facilities, process and quality control technology, and raw materials sourcing techniques – and in the quality assurance system which monitors all of the above. We view each cured-in-place pipe as a unique project, and take special care to produce a liner perfect for the job. Every liner we manufacture is tailored to the customer, fully compliant with industry standards, and of the highest quality.
