The preliner is a thin but resistant protective PE film tube (approx. 200 μm). It is pulled or inverted into the host pipe prior to liner installation in order to form a barrier between the pipe wall and the liner to prevent the resin from direct contact with the host pipe, or avoid damage to the liner.

  • Always use a pre liner in groundwater-saturated zones, where infiltration is present (groundwaterinfiltration)

  • For rehabilitation of displaced joints where water accumulations before liner installation cannot be avoided

  • Absolutely necessary if using the rapid ambient curing epoxy resin systems epros®EPROPOX FC15 or FC30

Sizes: DN 100 to DN 1000
