Renovation with the Tight In Pipe method (TIP)
The TIP method is a method for re-lining concrete and vitrified clay pipes with single pipes (short pipe) or pipe strings (long pipe).Firstly a new pipe made of polypropylene (PP-HM) is installed to fit closely inside the old pipe (tight-in-pipe). The tiny annulus needs no grout after fill.
