Pipeline rehab and lining technologies, ranging from high-density polyethylene liners to steam-cured epoxy systems, are designed to extend the lifespan of pipelines significantly while minimizing environmental impact. By providing a barrier against corrosion, infiltration, and exfiltration, methods like those below not only preserve the structural integrity of pipelines but also enhance their functionality.
AGRU America Sure-Grip
Sure-Grip liners from AGRU America are made of HDPE, HDPE-el, PP, PVDF or ECTFE, and serve as a long-term alternative to spray-applied concrete protection products. The liners prevent concrete corrosion and degradation, can substantially extend the lifetime of a structure, and by preventing exfiltration and infiltration, provide direct protection for the environment. The liners have anchoring systems that enable construction in areas of significant backpressure. Unlike spray-applied liners, which have to be reapplied regularly due to cracking or delamination, these liners are long-lasting, and are designed to avoid the residuals cost often associated with concrete spray-on liners, which require tank emptying and cleaning every few years for reapplication.

FORMADRAIN Formapox 101
Formapox 101 from FORMADRAIN is a durable steam-cured liner that eliminates the mess and cost of traditional dig-and-replace methods. It is made from a watertight, thin, yet extremely strong composite material and a specially formulated resin. The liner is bright blue in color. It is the mainstay of the company’s pushed- or pulled-in-place, steam-cured, fiberglass and epoxy underground pipe repair system. It can be used in line sizes from 2 to 48 inches. The repair is so thin that pipes sustain their original flow capacities, even with a liner installed in such small diameters.

MaxLiner USA GhostLiner
GhostLiner lateral CIPP liner from MaxLiner becomes transparent during wet-out, reduces UV cure times by up to 50% and delivers superior physical properties. It offers a faster and higher quality cure due to transparency once saturated, and negotiates pipe bends up to 45 degrees. It is a uniquely manufactured synthetic fiber felt with a TPU coating designed to maximize LED light-cure capabilities. Tube forming and seam bonding are achieved by an overlocking chain-stitched seam with an extruded taped joint creating a superior, high-performance impermeable liner designed for sweeping bends up to 45 degrees and very minimal stretch.
