What is a Root Barrier?

A root barrier is a specially designed membrane that is installed in the ground to protect structures and services against tree roots, Japanese Knotweed and other invasive plant species.

DENDRO-SCOTT™ Root Barrier can be installed:

  • Vertically, to protect the perimeter of a site or between structures and trees (depending on the distance between the two)
  • Horizontally, to protect new builds, paths, roads etc.
  • To build a ‘Cell’, to bury Japanese Knotweed contaminated soil on site

DENDRO-SCOTT™ Root Barrier is a polyethylene-based membrane, known for it’s flexibility, which makes it easier to install and ‘mould’ to fit the desired shape. It comes in a wide range of sizes and can be jointed on site with tape. Peter Scott Tree Care (Southern) Limited supplied the UK Market for all-sized projects, from small domestic to large developments.

Low impact root barrier installation

Drain Scan have developed a lower impact method of root barrier installation using a slot trenching machine designed and built by Bob Freeborn, specifically for use with the Dendro-Scott root barrier system.

As shown in the photos and videos below, installation of the root barrier material is carried out by digging a narrow trench of 170mm wide up to 4.3m in depth.  Where site and soil conditions allow its use, this method substantially reduces site impact and cost of site restoration.
