Keeping roots from growing in sewer line is something that many homeowners are not aware of until it is too late. The tendency for roots to seek out sources of moisture draws them to your sewer line, and this effect increases over time as your pipes develop leaks from age, stress and general wear. Often, the only sign that damage has occurred is a tendency to clog or drain slower than normal. Fortunately, there are ways to keep damage from occurring.

Physical barriers

Some of the most effective methods of preventing root damage include the installation of barriers to those roots. This can be accomplished with a wide range of materials including copper, plastic, steel, and even slow-release chemicals meant to biologically inhibit growth. However, the most effective barriers are made of porous stone like large gravel that has been encased in concrete, which can provide a barrier of air that slows or stops roots from growing in sewer line.

Barrier Types:
• Copper
• Stone
• Steel
• Plastic
• Chemicals


As long as you know where they run, you can take an active approach in keeping roots from growing in sewer line. If you notice any large roots stretching in the direction of your existing line, you can dig them up and cut them. You may even consider pulling any trees up that are too close. When you are planning your landscape, you should consider your sewer lines in order to avoid placing any strong rooted plants like trees near them. Instead, opt for smaller shrubs and bushes that have a smaller root reach.

In Conclusion

You are not left without options when it comes to preventing or repairing root damage.
