When using the patented Repiper® tools and the StepbyStep method neither the floors nor the walls have to be broken up, which minimizes disturbance. The entire process only takes a few days and is carried out at a fraction of the price compared to traditional methods. The end CIPP product has a certified expected service life of at least 40 years and the result is a new tightly sealed and self-supporting pipeline system within the old one, with no seams risking water infiltration between the host pipe and CIPP liner!
