Unique Methods to Rehab Both Ends of the Spectrum

Speaker: Rick Gage, Vice President Sales, LMK Technologies

 

Mainline pipes and their lateral connections vary in sizes. Therefore, there is a need for a variety of trenchless rehabilitation techniques that complement each situation. This presentation focuses on the challenges and solutions of renewing the connections in 6” and 27” or greater mainline pipes without digging. Small-diameter mainline pipes have always been challenging.  These repairs are very similar to the installation methods practiced in ASTM F2599. The mainline tube and lateral tube are simultaneously inverted as a one-piece, main-to-lateral connection utilizing molded hydrophilic gaskets. Until now, standard and repeatable trenchless rehabilitation solutions have not been available to adequately repair large diameter pipes and their connections to the lateral. The finished product provides a water-tight connection by utilizing molded, hydrophilic gaskets.
