History

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 situ form," which means to "form in place." The first CIPP tube was installed in the UK in 1971 and is still in service today. A CIPP system consists of a flexible felt or fiber-reinforced tube impregnated with resin. The tube is inserted into an existing pipeline by either inversion or via a pull-in method. It is then cured with steam or hot water, providing a new jointless pipe within a pipe.{{cite web|title=Insituform CIPP process is suited for wastewater pipeline repair|url=https://undergroundinfrastructure.com/magazine/2016/april-2016-vol-71-no-4/equipment-spotlight/insituform-cipp-process-is-suited-for-wastewater-pipeline-repair/|website=Underground Infrastructure}}

In 2007, Insituform announced that it would exit the tunneling business and seek a buyer for Affolder, Inc.{{cite web|url=http://milwaukee.bizjournals.com/milwaukee/stories/2007/04/09/story17.html|title=Deep tunnel contractor to be shut down|author=David Schuyler|date=April 8, 2007|publisher=Milwaukee Business Journal}}
