| Sliplining Sliplining is one of the pioneering processes used in trenchless rehabilitation of pipelines. During the process, a new liner of smaller diameter is placed inside the existing pipe. The annular space, or area between the existing pipe and the new pipe, is typically grouted to prevent leaks and to provide structural integrity. Continuous grouting of the annular space provides a dependable seal. In most sliplining applications, manholes cannot function as proper access points and it may be necessary to dig an insertion pit for each pipeline segment. Though not a completely trenchless technique, the excavation required is considerably less than that for traditional methods. |
