Lateral sewers will usually last for about 40 years, though the lifespan of the sewer can vary depending on other conditions. But eventually, cracks and tree roots will cause serious leaks that will make the sewer non-functional. When it is time to replace it, the conventional approach is to dig up the sewer in order to perform the repairs. However, there are now trenchless sewer line repair options available that cause less damage to your property.
Identifying the Cause of the Sewer Problem
Before having your lateral sewer repaired with a trenchless repair option, you will need to identify exactly what the problem is with a sewer camera. The camera is run though the sewer line, allowing the repair technician to identify the root problem.
Determining Whether You Should Use Trenchless Pipes
Use this method if you must repair pipes that run underneath your landscape. Trenchless sewer repair is intended for sewer pipes that have burst because of:
Repeated pipe freezing and thawing
Traditionally, you would need to dig a trench alongside the pipe to be repaired. But with trenchless repairs, you will dig a much smaller insertion pit and will not have to remove as much vegetation. A usable portion of the pipe is removed so it can later be replaced. Obstructions to the pipe liner must be removed as well.
Using the Pipe Lining Method
One method of pipe repair, pipe lining, uses a flexible tube that is covered in resin and pulls the tube into the pipe. The tube is then expanded and the resin hardens, which creates a seamless pipe within a pipe. The process usually takes less than a day.
Bursting the Old Pipe Instead
Pipe bursting involves the destruction of the original pipe so it can be replaced with a new one. It is usually necessary to dig access holes to the outside of the pipe. A large cone is pulled through the pipe by a hydraulically-powered cable. The bursting head burrows into and shatters the old pipe, pulled by chain links.
Both methods are considered to be just as durable. However, the pipe lining method might be impossible if the lateral has joints or when a portion of it has collapsed. Regardless of the nature of the burst pipe, there is a way that you can restore your sewer to full functionality with a corrosion-resistant pipe.
