If you have a problem with a drain, then you can sometimes use no-dig repair techniques. However, there are times when traditional excavation is the best way to fix broken drains and their underground pipes.
When might excavation be the right way to fix your problem?
1. No-Dig Fixes Won't Work on Your Pipes
No-dig repairs fix broken drains without digging up the ground above and around the pipes. However, this method won't work on all pipes.
For example, some pipes aren't the right material or size to take a no-dig patch or reline. Some are so damaged that an internal patch or reline won't be enough to fix the problem.
Here, an overground excavation makes more sense. Your contractor can repair or replace damaged parts of your drainage system more effectively.
2. You Have a Difficult Blockage
If your drains are blocked, then a no-dig solution will sometimes clear the blockage out of a pipe. For example, you can use water jetting to force a blockage out through the system. Or, you can insert special cutters into the pipe to cut out tree roots that have grown inside a pipe.
However, not all blockages are easy to remove. If you have a large clog in a pipe that just won't shift, then you might need to excavate the pipe to clear the blockage. Some tree root growth is so extensive that you have to open up the pipe to clear the roots.
Plus, if your pipes are old and corroded, then no-dig fixes can cause more damage. The force you have to use to clear a stubborn blockage could also make a rusty pipe crack and break.
In these cases, drain excavating makes more sense. You can remove parts of the system that are blocked and clear them out before reinstalling them. You get an effective fix without making things worse.
3. You Have Soil Support Problems
In some cases, drain problems are caused by soil support problems. For example, if you have some subsidence around a pipe, then the pipe loses some support. If it sinks down, then it could break at a joint and start to leak.
A no-dig solution might not work if the pipe doesn't run straight and on an even level. It might fix the pipe, but it won't deal with the underlying soil problem.
A full drain excavation allows you to repair your pipe. It also gives you ground access. Your contractor can fix your soil problem as well.
