Description of Main
Features
Main Benefits
Claimed
AM-Liner II is manufactured from PVC specially formulated for pipeline
rehabilitation. The AM-Liner II is pulled into the host pipe and thermoformed
creating a seamless, jointless, solid wall PVC pipe that tightly conforms to the
interior contours of the original host pipe.
• Installation can be done in under 4 hours – minimizes by-pass pumping and
traffic control
• Liner is manufactured in a controlled environment, not in the field.
• Installed only by trained licensed contractors.
• PVC is resistant to all chemicals normally found in a sewer.
• Smooth interior – low friction factor
• No experience with pressure applications
Main Limitations
Cited
• Not cost competitive with CIPP in diameters over 12 inches
