1. Cut Tree Roots Mechanically
One of the most common techniques is to use a Drain Cleaning Machine. The mechanical method of root removal involves sending a powered sewer auger down a sewer line. The rotating head is covered in teeth much like a reciprocating saw blade. The rotating action cuts the roots, clearing roots out , but they will start growing back almost immediately.
2. Chemical Tree Root Removal
There are special chemicals designed to kill a tree’s root structure
so it doesn’t grow back. Copper sulfate septic treatments are the most
common. This method is especially effective as it creates a poison
barrier within the soil that kills the tree roots before they can grow
into the pipe. Treatments that include foaming agents have the added
advantage of coating the entire pipe, saturating the roots that grow
from the top as well as the bottom.
3. Remove Tree Roots With a Hydro Jetter
An effective, but potentially expensive, way of clearing sewer lines is with a hydro Jetter. This machine uses a pump and pressurized water. After the hydro Jetter does its job, the sewer line can be flushed with a chemical to kill any roots still present.
4. Dig Up Invasive Tree Roots
Sometimes a sewer line can’t be cleaned or cleared with chemicals, a hydro jetter or an auger if it’s been damaged too badly. To assess the extent of the damage, consider investing in a camera that records the inside of the line. A camera system allows a technician to show the homeowner exactly what needs to be done to correct the problem. In some small cases sewer line replacement is necessary,
