When rehabilitation technologies cannot be effectively restore preexisting pipes or when a bigger cross-section of the pipe is required then no-dig replacement methods can be really the solution.
Fast, cheap and easy-to-use, no-dig replacement methods allow the replacement of any kind of material ranging from concrete to steel.
In order to rehabilitate gravity or pressure pipes, with diameters ranging from 100 to 1.800 mm (4 to 78 inches), several no-dig technologies are available today:
