Tree Root Blocker


SKU MM-HDPE-18-80-100

Our tree root blocker is made of heavy duty HDPE and designed to protect landscapes and hardscapes from damage from tree roots. The material is shipped in a 100’ roll (48" depth ships in a 80' long roll) which provides a long span without joints. This is a major advantage when comparing to other root barrier solutions which rely on panels which can be prone to root intrusion where the panels connect. The root blocker is available in roll widths racing from 18” to 48”. The material thickness is 80 mil which is able to stop even the most persistent roots from various tree varieties. It is recommended that an inch is left above the ground when installed so that surface roots can be quickly identified and clipped. The barrier provides an approximate 100 year lifespan when installed in the ground.

The material is manufactured in the USA.


Note: Our HDPE plastic is only available in roll widths up to 60 inches.

Please note that we are unable to provide custom roll lengths.
