Rootline Root Barrier

Rootline Root Barrier

Rootline is available as both impermeable flat sheets and as an impermeable cuspated sheet.

Rootline Root Barrier

Rootline is a root barrier developed to protect highways, foundations, waterproofing, pipes and other services, etc. from damage arising as a result of tree root penetration.


  • Rootline can be installed vertically as a barrier around trees to prevent the lateral spread of roots. The roots are deflected harmlessly downwards.
  • In Green Roofs Rootline is installed horizontally above the waterproofing and offering protection from root penetration


  • Protects structures from damage arising as a result of root penetration.
  • Controls roots without damaging tree root structure

Tree roots predominantly grow in the upper surface of the soil and spread out extensively laterally from the trunk. A good root system is essential to sustain healthy tree growth but the roots can be deflected to grow harmlessly to avoid damage to adjacent structures or services.

Rootline can be installed around the tree or adjacent to the structure or wrapped around the pipe, etc. Rootline is available in two styles and each consist of robust flexible polymer (HDPE or LLDPE) sheets that resist penetration by roots.

The plain Rootline is the most economic but the dimpled and pocketed Rootline is the most effective in vertical applications. The pockets guide the roots into a downward direction.


Rootline is available in two types:

  • Rootline GHD85, 120, 200 are water impermeable HDPE with a plain surface
  • Rootline GLLD100S3 is water impermeable LLDPE with a 3mm dimpled surface
