How does the high volume water jet cut tree roots?
An assortment of nozzles are available for varying tasks. The standard jet nozzle will cut fine roots and remove debris. For larger roots we use either hydraulic root cutters or chain flail root cutters. 5 How do you know when the pipeline is clear? This is a very interesting question. With the aid of our close circuit television cameras which we are able to insert into pipelines we have discovered that in most situations where invasive tree roots are detected, it is very difficult to remove sufficient amounts of the roots by using mechanical cleaners such as electric eels or just water blasters. Quite often the blockage is cleared but the roots causing the problem remain. They may simply have been pushed out of the way and will cause further problems later.
