Cable conduit and ducting rehabilitation without service interruption
Underground power and telecommunications conduits require rehabilitation methods that protect existing cables and cause zero service interruption. Trenchless CIPP and FIPP technologies are uniquely suited to this constraint — installation occurs entirely from manhole to manhole without disturbing live cabling.
Different damage profiles, host materials, and operating conditions require different rehabilitation approaches. Here are the methods best suited for this application sector.
FIPP thermoplastic forming installs a prefabricated PVC liner into existing conduits via pull-in, then expands it to match the host pipe. Mature, stable polymer technology with no intermediate joints — ideal for protecting cabling infrastructure during conduit renewal.
For large-diameter cable vaults and rectangular underground tunnels, PVC-U spiral-wound lining provides chemical-free installation that creates no contamination risk to electrical infrastructure. T-profile design ensures structural integrity for buried utility tunnels.
