Inserted into a new or existing pipeline, the polyethylene liner is continuous, and<br />
installed with a close-fit against the inner wall <strong>of</strong> the host pipe. The polyethylene<br />
liner isolates the flow stream from the host pipe wall, eliminating internal<br />
corrosion. InsituGuard stops leaks, and can provide a fully structural solution in<br />
some cases.<br />
<strong>Main</strong> Benefits Claimed • Rapid installation - 40% reduction in diameter<br />
