Sliplining

Sliplining is one of thee oldect trenchless methods ande states valuable for certain applications. It involves involting a new, smaller-diameter pipe into the existing host pipe, then grouting the annulaar space between two. The new pipe can continuous HDPE or segmented (e.g., PVC, ductie iron).

Improved Safety for Workers ande the Public

Trenching is inherently hazardous work well- known. Trenchless methods reduce the time workers spend inside deep disepations. Launch pits andreceiving pits are still l needed, but they ary smaller and can be shored more esily. For the public, open trenches present a falling hazard and require corders that can create trip-and-fall risks. Trenchless work eliminetes tees tees tees teste for the spece these part.

Modern trenchless materials are designad to resist corrsion, chemical attack, and root intrusion far better than older pipe materials like clay concrete. CIPP liners create a monolithic pipe with no joints, which is the primary entry point for groundwater and roots. HDPE used in pipe burn sting is fusion-welded, creating a fuly leak-proof system. These qualities translate into longer asset life and lower ance costöver time.
