In the trenchless industry, there are a wide variety of trenchless technologies. Directional boring, pipe lining, pipe bursting, and hydro evacuation are just a few processes that solve a variety of pipe problems in a non-disruptive way. When it comes to knowing which of these methods is best for your failing pipes, understanding the facts can help you know what your options are to fix your pipes.
Trenchless Pipe Bursting
Pipe bursting also known as pipe splitting is a common trenchless method used to replace buried or failing pipelines. Pipe bursting is commonly used when the pipe has gone too far and the pipe has collapsed in on itself. If the pipe was only cracked or the joints misaligned it could be possible to save the original pipe through another trenchless technology method called pipe lining. The installation of pipe bursting is commonly used for underground sewer pipes and large diameter water mains. The process involved two access points, at the beginning and end of the failing pipe. Once exposed, a bursting head that is slightly larger than the existing pipe is either pushed or pulled forward into the pipe. This motion shatters the old pipe and pushes the shatters bits of pipe to the side, which results in a clear space for the new pipe. Then the new pipe is pushed into place behind the bursting head and is then attached to the existing pipe ends. Pipe bursting from a cost perspective is less expensive than a traditional re-pipe that involves digging a trench. This trenchless method can help property managers and homeowners avoid tearing up lawns and pavement to solve their sewer or water main pipe problems.
Trenchless Pipe Lining
Pipe lining technology has been around for decades and has continued to grow in popularity as a no-dig solution to corroded, cracked, and deteriorating pipe systems. There are products specifically designed for non-pressurized pipe systems such as sewer drains and even pressurized pipe systems such as potable water lines. CIPP lining is a known solution for solving cracked or deteriorating drain pipes. The process includes inspecting the damaged pipe and identifying where the damage is located and then the pipe is prepped for the liner by a variety of cleaning methods. An epoxy saturated liner is pulled through the pipe with a bladder inside which is then expanded to allow the epoxy liner to cure – adhering to the host pipe. The process is a structural pipe within the original damaged pipe. CIPP lining avoids tearing up lawns, pavement, and floors that would have to be opened to access and re-pipe the damaged pipe.
The major difference between pipe busting and CIPP lining is knowing what kind of condition your pipe is in and the location. Identification is key – the condition of your pipe can often be determined by a camera inspection and an expert pipe specialist who has experience in determining pipe conditions. Before you start digging up your floors or lawns with a traditional re-pipe repair consider using a trenchless technology solution.
