Root Barriers

ROOT BARRIERS

A root barrier is an underground wall that effectively separates plants (such as trees and bushes) and hardscapes (such as the base of sidewalks and driveways) so they don’t interfere with each other.

Without a root barrier in place a tree’s roots could creep over to your sidewalk and bust it up or tree roots could end up cracking a foundation. Tree roots are also notorious for damaging utility lines. Some types of trees have roots that are only mildly invasive but others can be quite aggressive. Either way, it’s best that they’re contained, as out-of-control roots can wreak havoc on any yard.

Root barriers can be mechanical or chemical. While chemical barriers work by essentially stopping the root in its track, it also kills the tree roots it comes in contact with, so it’s not ideal. Mechanical root barriers, on the other hand, work with the roots, allowing them to grow – but re-directing them downward.

When you plant a new tree in your yard, consider using a root barrier to avoid future repairs and damage to nearby hardscapes. As for existing trees, root barriers can be installed around them, too.
