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