Root Barrier

Do you need a strong, flexible yet durable membrane to help combat your tree roots problems?

Do you want a product that is reliable, resistant against chemicals yet will not blow your budget?

Let me introduce you to:

Root Control Membranes

Root Control Membrane barrier is made from Virgin High Density Polyethylene (HDPE) not recycled HDPE which breaks down quickly. Versatile and UV resistant virgin HDPE provides strength and integrity in the material making it the perfect product for protecting walkways, roads and building foundations as well as solving all of your landscape gardening requirements.


Root Control Membrane barriers have ultraviolet chemical stabilisers added to the membrane enabling a life span of 10+ years when exposed and up to 20 years if fully covered. It also has good resistance against many agricultural chemicals and pesticides as well as most soil types including salty soils. The membrane is tough and durable enabling it to control tree roots and soil moisture.


Root Control Membranes offer a superior product at a competitive price giving you both an affordable and reliable alternative for your root control needs. When you consider the costly damage that can be caused, Root Control Membrane is a very affordable solution.

Trees and Foundations

Important Safety Awareness: It is important to seek the advice of trained Arboriculture Specialist or Urban Tree Root Specialists to assess the health, integrity and stability of the trees and their ability to respond to root pruning and root barrier use. Their knowledge and experience in knowing which roots can be safely cut will prevent any risk of the tree falling over in strong winds.


These services will also take important measures to locate and prevent damage to underground utility services and allow for excavation that does not create disruption.


The roots of some trees which develop large base structures may cause direct physical disruption of minor structures such as footpaths, fences or simple retaining walls. Damage to houses is far more commonly associated with clay shrinkage.


Tree roots may damage the footings of buildings in two ways:

  • By direct physical contact, or
  • By removing soil moisture which causes shrinkage of clay soils and subsequent settlement of adjacent footings (conversely, the removal of trees from a site eliminates their drying effect and permits soil wetting with subsequent heave).

In the majority of cases single trees will not interfere with footings if they are planted a distance away greater than their expected mature height. Where a group of trees are in close proximity the minimum of planting distance must be increased to 1.5 times the mature height of the trees.

Australian varieties of trees and shrubs use large amounts of water in normal conditions. This problem, especially when combined with reactive clay soils can cause substantial damage to the foundations of buildings walls pathways and roads.


The root barriers are installed so that they intersect imaginary radial lines extending from the trunk of the tree to the edges of the foundation. The trench created to install the root control membrane is usually made narrow enough to minimise the degree of site disturbance. 


The root barrier prevents moisture from moving sideways through the soil. Minimising moisture loss that can take place and thus future movement from this cause is prevented. Once moisture content is stabilised and the building returned as close as possible to normal, repairs to cracks etc in the building can be completed.
