What is RootGard 

RootGard Root Barriers are versatile and made of extremely tough polyethylene to protect hardscapes and landscapes from damage by tree roots. When used around building foundations, RootGard™ also prevents root intrusion.

RootGard reduces maintenance costs and damage caused by root intrusion and may be installed for both new and established planting.

RootGard can be installed both in linear and circular style planting.
