Guarding pipes from Tree Roots
Guarding pipes from Tree Roots
(OP)
I have an existing asbestos cement pipe that I will be planting trees almost directly above. The pipe is old and is estimated to have 3.5' of cover. We plan on planting shallow rooting trees but I would also like to use some sort of root guard for added protection.
Does anyone have any products/practices they could suggest?
Thank you.

"Sec. 4.1 Permeation
The selection of materials is critical for water service and distribution piping in locations where there is likelihood the pipe will be exposed to significant concentrations of pollutants that are comprised of low molecular weight petroleum products or organic solvents or their vapors. Research has documented that pipe materials, such as polyethylene, polybutylene, polyvinyl chloride, and asbestos cement, and elastomers, such as used in jointing gaskets and packing glands, may be subject to permeation by lower molecular weight organic solvents or petroleum products. If a water pipe must pass through such a contaminated area or an area subject to contamination, consult with the manufacturer regarding permeation of pipe walls, jointing materials, etc., before selecting materials for use in that area."
