Pipe renovation is also called lining, pipe lining, riser renovation, flexible liner and pipe-in-pipe, "a cherished child has many names".
Old pipes turn into new ones (internally)
Pipe renovation is a collective term for renewing old and worn pipes. Traditionally, piping systems are renovated by replacing pipes and conduits with new ones. With pipe relining old pipes can be renewed without needing to tear out the existing pipes. This entails significantly lower costs, with the minimal of waste and disturbance to residents as well as a substantially faster work process.
Renovation using polyester plastic, to which our own Proline method belongs. Proline Group was the first to use this method. Usually the new pipe is moulded in several layers with a period of hardening time between each layer.
Flexible liner (sometimes also called the sock technique) where a epoxy-impregnated polyester liner is twisted into or pulled into the old pipe and allowed to harden. This includes our Prosoc method.
