Cured-in-Place Pipe (CIPP): Cured-in-Place Pipe, commonly referred to as CIPP, is a trenchless rehabilitation method used for repairing or renewing existing pipelines without excavation. It involves inserting a flexible liner into the damaged pipe. The liner is typically made of resin-saturated felt or fiberglass.

Excavation is critical in any construction project that involves removing dirt, rocks, and any unwanted materials from a site in order to build a strong foundation for a structure. When it comes to road construction, good excavation work is the first step to a strong and stable subgrade, thus demanding execution with precision using the right ...
Chapter 15: Excavation Principles. In this chapter, we explain the fundamental principles of rock excavation. Initially, the excavation process is discussed in its most basic form, i.e. reaching the post-peak region of the complete stress-strain curve and altering the in situ block size distribution to the excavated fragment size distribution.
