The World’s Largest Installed CIPP Rehabilitation in 2018 was our 72 inch liner installed for the New York Department of Transportation in upstate New York in collaboration with partners Arold Construction.

Since this project, IMPREG has broken our own record of largest liners installed as we have established ourselves as the Global Standard for large diameter CIPP lining, but we will never forget the thrill of designing and innovating this 72″ to sustainably move the industry to more sustainable practices for large pipe restoration.
