<strong>Main</strong>Saver is a flexible MDPE tube with integral grout key hooks on the outside<br />
surface, which is inserted into the main, then a pre-determined quantity <strong>of</strong><br />
proprietary cement grout is placed between the outside <strong>of</strong> the tube and the inside<br />
<strong>of</strong> the host pipe. Air pressure is used to move a rounding swab along the length <strong>of</strong><br />
the liner, which progressively expands the tube and distributes the grout against<br />
the interior surface <strong>of</strong> the host pipe, physically filling all pipe defects. <strong>Main</strong>Saver<br />
is used to renew pipes with holes, displaced joints, leaking joints, <strong>of</strong>fsets <strong>of</strong> no<br />
more than 12.5% <strong>of</strong> each joint and maximum 22 o long radius elbows. It is NSF 61<br />
certified <strong>for</strong> use with potable water.<br />
<strong>Main</strong> Benefits Claimed • Simple system, easy to install<br />
• Low installation cost<br />
• Suitable <strong>for</strong> use with all types <strong>of</strong> pipes, particularly ferrous, asbestoscement,<br />
rein<strong>for</strong>ced concrete, and pre-stressed concrete cylinder pipe.<br />
• Cement provides active corrosion protection (ferrous mains) and the PE tube<br />
ensures water quality<br />
• Prevents leakage<br />
• Service connections can be reinstated robotically to reduce excavation<br />
requirements.<br />
<strong>Main</strong> Limitations Cited • Ideal installation temperature range is between 40°F and 80°F, although<br />
<strong>Main</strong>Saver has specific hot and cold weather installation procedures.<br />
• Designed <strong>for</strong> pressure pipes only.<br />
Applicability<br />

Service Application Potable water, raw water and <strong>for</strong>ce mains<br />
Service Connections <strong>Main</strong>Saver uses its RoboTap method <strong>for</strong> remote robotic service connection<br />
reinstatement after the <strong>Main</strong>Saver composite has been installed. This eliminates<br />
the need to excavate the main to reinstate service connections.<br />
