Sewer pipe lining could be a good option for repairing your cracked sewer drain. It's effective, and a liner lasts for several decades. Here's a look at why putting in a pipe liner is often better than digging up the broken pipe and how sewer pipe lining is done.
Why Lining The Pipe Is A Good Option
Having a liner put in the sewer pipe could save you a lot of money over having the pipe dug up and replaced. This is especially true if the sewer pipe runs under your driveway or under a shed. When an old pipe is dug up, everything on top of the pipe has to be dug up to get it out of the way. That could entail tearing out landscaping or busting up concrete.
None of that is necessary when you have a liner put in instead. The contractor has to dig access holes to reach the ends of the pipe, but your yard doesn't have to be torn up since the old pipe stays in place under the ground.
A Sewer Pipe Liner Can Be Cut To Any Length
A benefit of a liner is that it can be cut to any length. This is beneficial because it eliminates seams in the sewer pipe that might start leaking or get pried apart by tree roots. The contractor can cut a liner that is the length of the entire sewer drain, so you get a new drain with no seams when the work is done.
The contractor can also cut a smaller length of the liner to use as a patch if they just want to make spot repairs to the old pipe. Before work begins, the contractor will probably look in the damaged pipe with a camera, and this helps the contractor pinpoint damaged areas and determine if a patch is a suitable repair option.
The Pipe Liner Hardens Into A New Pipe
There are a few approaches to installing a pipe liner, but a typical option is to push the liner through one end of the old pipe and pull it out the other side. The liner is usually flat for this process, and once the liner is positioned, it is inflated to form a new pipe. The outside of the liner sticks to the pipe and cures in place.
After the liner is hard, it becomes a new pipe within the old one, and the old pipe stays in place. You may have two small holes to fill and cover with grass when the work is done, but you won't have to repair any structures in your yard since the liner can be pulled under a driveway or even under a building slab.
