Panel Lok uPVC Manhole Lining System

Panel Lok is designed as a bonded structural liner which forms a composite pipe section with the host pipe. Long term bond between Panel Lok liner and grout, and bond between grout and existing pipe, will transfer shear stress generated by composite action. Panel Lok – 17/300 (Extra Heavy) – Used for Corrosion protection and structural enhancement of gravity and low pressure pipelines DN800mm to DN1400mm and of maintenance holes and wet well chambers. Other profiles are available to suit client sizing needs.

After the manhole is pressure washed the Panel Lok profile is fed through the manhole lid and spiral wound into place by hand and interlocked with a joining strip. There is minimal loss of cross section as its formed hard against the host walls. The top and bottom of the liner will be sealed with Sewpercoat with no waiting time on curing and no acid washing surfaces compared to other systems. Once the liner is installed grouting is pumped behind the liner in 1 meter lifts to complete the structural bond.
