  NASTT's 2012 Introduction to Trenchless Technology Short Course Rehabilitation Pt 2 Session 2


Pipe Bursting is a technique for breaking existing pipe by fracture using applied mechanically force from within.  The pipe remains are forced into the surrounding ground by this action.  At the same time, a new pipe of the same or larger diameter is drawn in behind the bursting tool.

Sliplining is the insertion of new piping inside larger existing buried pipe and is often referred to as the grand-daddy of trenchless.  Generally, the host pipe must be cleaned before a segmented or continuous pipe is inserted either by pushing or pulling.  Grouting of the annular space is often recommended.

Spiral Lining is where a ribbed plastic strip is mechanically spirally wound to form a liner which is inserted into a defective pipeline. The annular space may be grouted or the spiral liner expanded to reduce the annulus and form a close-fitting installation.

Spot Repairs are repair work on storm and sanitary sewer piping at specific points between manholes.  Spot repairs can produce considerable savings fixing only what needs to be fixed rather than an entire length of sewer.

Grout in Place Lining Systems are designed to fill the annular space between the host pipe and the carrier pipe.  Grouting is also used to fill the space around laterals and between the new pipe and manholes.

Manhole Rehabilitation is the process of repairing an existing structure without excavation.  Numerous methods are commonly used such as a cured in place fitted liners; chemical grouting; hydraulically applied cement; etc.
