Root Barrier 1.3mm thick


(2 customer reviews)

Trees and shrubs, although beautiful, often invade man-made structures with their roots. Root Barrier acts as a continuous, physical barrier to minimise the damaging effects of tree roots to pavements, foundations, driveways, roads and pipes.

Our Root Barrier is tough, flexible and virtually indestructible – it will never rot, rust, splinter or crack. Plus it’s made in Australia from over 90+% Low Density Polyethylene (LDPE)  plastic which is more resistant to brittleness and Environmental Stress Cracking than those made from High Density Polyethylene (HDPE).

It is suitable for use as a barrier to a wide range of roots including: grass, mint, bamboo, monkey grass, palm trees, weeping willow, bermuda grass, knotweed, raspberries, ficus and pine trees.

GreenMongrel Root Barrier is:

  •  A solid 1.3mm thick product (not a thin sheet, embossed to make it appear thicker)
  • Made from over 90+% LDPE blended recycled plastic for improved resistance to Environmental Stress Cracking compared with HDPE
  • “.. lower density polymers offer better resistance to ESC (Enviromental Stress Cracking)” than HDPE.  See link to paper below.
  • Lightweight and flexible
  • UV stabilised  and waterproof
  • Tough and durable – will not rot, rust or crack
  • An impermeable barrier against moisture loss
  • Fungus and bacteria resistant
  • Australian made
  • Recyclable
  • Easy to install
  • For big jobs an automatic trencher may be used ( for example, visit )
  • Colour: Black
