2. Cured-in-place pipe - Wikipedia

   en.wikipedia.org/wiki/Cured-in-place_pipe

   Sewage repairmen inserting uncured liner into a soon-to-be repaired pipe A cured-in-place pipe ( CIPP ) is a trenchless rehabilitation method used to repair existing pipelines. It is a jointless, seamless pipe lining within an existing pipe.

3. Sprayed in place pipe - Wikipedia

   en.wikipedia.org/wiki/Sprayed_in_place_pipe

   Sprayed in place pipe (SIPP) technologies is a trench-less rehabilitation method used to repair existing pipelines, that involves a robotic lining system that develops and manufactures proprietary lining polymeric. SIPP is a jointless, seamless, pipe with in a pipe with the capability to rehabilitate pipes ranging in diameter of .1 to 2.8 ...

4. Trenchless technology - Wikipedia

   en.wikipedia.org/wiki/Trenchless_technology

   Pipe replacement by pipe bursting. Trenchless rehabilitation includes such construction methods as spiral wound lining, sliplining, thermoformed pipe, pipe bursting, shotcrete, gunite, cured-in-place pipe (CIPP), grout-in-place pipe, mechanical spot repair, and other methods for the repair, rehabilitation, or replacement of existing buried pipes and structures without excavation, or at least ...

5. Pipe bursting - Wikipedia

   en.wikipedia.org/wiki/Pipe_bursting

   Pipe bursting is a trenchless method of replacing buried pipelines (such as sewer, water, or natural gas pipes) without the need for a traditional construction trench. "Launching and receiving pits" replace the trench needed by conventional pipe-laying.

6. Sliplining - Wikipedia

   en.wikipedia.org/wiki/Sliplining

   It involves installing a smaller, "carrier pipe" into a larger "host pipe", grouting the annular space between the two pipes, and sealing the ends. Sliplining has been used since the 1940s. [1] The most common material used to slipline an existing pipe is high-density polyethylene (HDPE), but fiberglass-reinforced pipe (FRP) and PVC are also ...

   Insituform Technologies, Inc. is a worldwide provider of trenchless technologies for gravity and pressure pipelines. Insituform is a subsidiary of Aegion Corporation. Insituform's inception was prompted by the invention of cured-in-place pipe (CIPP) by Eric Wood of the United Kingdom in the early 1970s. Its name comes from the Latin phrase "in ...

8. Pipe ramming - Wikipedia

   en.wikipedia.org/wiki/Pipe_ramming

   Pipe ramming (sometimes also called pipe jacking) is a trenchless method for installation of steel pipes and casings. Distances of 30 m (150 feet) or more and over 500 mm (20 inches) in diameter are common, although the method can be used for much longer and larger installations.

9. Directional boring - Wikipedia

   en.wikipedia.org/wiki/Directional_boring

   Directional boring, also referred to as horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig. Directional boring offers significant ...
