When constructing green roofs a root barrier will usually be required wherever the primary waterproofing system does not provide adequate root protection in its own right. In these situations Safeguard Root Barrier can be installed on top of the primary waterproofing system to provide a suitable root barrier. The other green roof layers (Oldroyd Xv 20 GreenXtra drainage layer, Oldroyd Tp filtration layer, growing medium) can then be laid on top.
In addition to providing a root barrier layer for green roofs, Safeguard Root Barrier can also be used to provide efficient protection against invasive root growth for urban infrastructures – e.g. piping, pavements, paved areas, roads, water and sewage networks, cabling etc…
Please note when ordering: Safeguard Root Barrier is cut from 2 metre wide rolls and sold in 1 metre lengths – i.e. each metre section measures 2 square metres.
For example, if you require 20 square metres of Safeguard Root Barrier you would need to enter an order quantity of 10.
