HL Liners with performance unmatched in the market can handle both dimensional changes and 90° bends with an absolute minimum of wrinkles. Combined with our NDW Resin the new sewer pipes will get a predetermined wall thickness of your choice.
Flex Liners are mainly used for installations in pipes with multiple bends or constrictions. They pass through bends more easily and can expand further than regular felt liners.
Pre-Liner is a flexible film tube that is inserted between the liner and the host pipes acting as a barrier between the host pipe and the liner. Pre-liners should be used when there is a risk of moisture or water infiltration, when the host pipe has rough surfaces or sharp edges that could damage the liner, or when direct bonding between the liner and host pipe is not desired.
