Pipe lining and pipe bursting are the two most popular non-invasive techniques for repairing sewer lines. Pipe lining involves inserting a resin-coated lining inside the old sewer line to create a new, smooth pipe. Conversely, pipe bursting entails breaking up the damaged pipe and replacing it with a new one. Both techniques are minimally invasive, but they vary in application and performance. Therefore, consider the factors below when choosing the best repair method for your sewer line.
Severity and Extent of Damage
The pipe lining method relies on the structural integrity of the old pipe. For this technique to work, the epoxy lining must adhere to the inner walls of the old pipe. Therefore, it works best for moderate pipe damage. If the sewer line is severely damaged or has collapsed, it may be too weak to support the weight of the epoxy lining. Also, the resin may fail to adhere correctly to the old pipe, causing sewer line failure.
Pipe bursting is the best repair technique for severely damaged sewer lines. The old pipe is pushed out, and a new one is installed in its place. This method allows you to replace sections of the sewer line without replacing the entire drainage system. Since this method does not rely on the strength or structural integrity of the old pipe, there is no risk of sewer line failure.
Location of the Damaged Pipe
The location of the damaged section of your sewer line can help you choose the best repair technique. If the broken sewer line is in a confined space, like a basement or under a concrete slab, you should opt for pipe lining. Pipe lining requires one access point to insert the liner. You can create a small access point without damaging interior flooring and concrete slabs.
Pipe bursting uses two sewer holes to burst the old pipe and insert the new one. Where utility holes aren't available, you must excavate the ground to create access points. Carrying out excavations in basements, under concrete slabs, and in confined spaces can be disruptive. Also, the equipment may be unable to access the space. Therefore, if your sewer line isn't severely damaged, opt for pipe lining.
Sewer Line Modifications
A sewer line repair project presents the opportunity to modify the system for improved wastewater management. However, modifications are possible only with pipe bursting. This method allows you to ditch the old, inferior piping material for a sturdier one. You can also upgrade the pipe's size, especially if your current sewer line clogs easily due to its smaller diameter. Therefore, if you want to upgrade or modify your sewer line, pipe bursting is the best technique for you.
