How to prevent tree roots from growing into the sewer line?

December 16, 2010 - 1:51 am

Cutting down trees is practically forbidden (municipal pro-tree movement). Is there such thing as a metal enclosure with small holes to fill with dirt and the sewer line? The holes would be to let any leaks from the sewer drain into the soil.

Or maybe line a trench with lumber or plastic sheets so that the sewer is within this trench structure?

Roebic makes FRK-12, a foaming root killer. You put it into your system by pouring it into your toilet as you flush it, and it begins to foam on contact with water.
The advantage to this product is that the foam fills the pipe and gets hung up on the roots and kills those invading your sewer - not just the roots which are in the bottom of the pipe. I put some in our sewer over a year ago and have had no trouble since. Good luck!

    I had the same problem until I replaced the tile sewer pipe with an ABS plastic pipe. Once glued, it melts the pipe joints together so you have one continous pipe without an opening for the roots to squeeze through.

    I wish I had replaced the pipe earlier instead of fighting the roots for years.
