Greenfix Soil Stabalisation

Introducing Greenfix tree root protection & Envirolok! The ideal choice for soil stabalisation and erosion control for a wide range of projects.  

We are proud stockists of Greenfix soil stabalisation products such as Envirolok and GeoWeb Tree Root Protection. These products provide sustainable and innovation solutions to areas of erosion and soil instability.

Envirolok Vegetated Bag System

This Envirolok product is designed to control the amount of erosion and protect the structural integrity of slopes. The system itself consists of soil bags, spikes, cinching and twine. Once the bags have been installed, native seeds are planted which encourages the system to lock in place through the growth of deep roots. Envirolok ensures that the land is secure, whilst also providing a vegetated finish which makes this product look natural, whilst prodiving a highly functional performance.

Where can Envirolok be used?

  • Slopes & Embankments
  • Stormwater Filtration
  • Wall Retention Applications
  • Shoreline Protection

Envirolok can be used to create a focal point, whilst serving the purpose of a gravity wall. It can reduce surface water run-off to mitigate the effects of erosion on embakments and slopes.

Geoweb Tree Root Protection

This Greenfix Geoweb Tree Root Protection is designed to redistribute the vehicle load from from vertical to lateral which protects the tree roots and allows the tree to survive. As the UK continues to expand its urban areas, it is essential to implement protection such as Geoweb, to give the tree roots space to grow whilst also allowing traffic to pass over them.

A Tree Protection Zone (TPZ) is a designated area around a tree or group of trees where development or disturbance is limited to protect the health and well-being of the tree.

The exact size of a TPZ varies depending on the species, size, and condition of the tree, as well as the specific site conditions. The purpose of a TPZ is to minimize the impact of development activities on the root systems of trees, which can be easily damaged by excavation, soil compaction, or changes in water availability.

By protecting the root system, the tree can continue to thrive and provide its many benefits, including shade, air purification, and habitat for wildlife.

When construction equipment protrudes the Tree Protection Zone, there is a negative impact to the soil. This includes compaction of the surrounding soil, damage to surface roots that are nearby, and the structural integrity of the tree is ultimately compromised.


Protecting trees in urban areas is crucial for several reasons; trees absorb carbon dioxide and other pollutants and produce oxygen, which can significantly improve air quality and reduce the risk of respiratory diseases. Trees have a significant impact on our quality of life as humans in terms of helping us to combat climate change, as they mitigate the effects of it by absorbing carbon dioxide.

As well as providing benefits to us, trees also provide habitats for wildlife, allowing ecosystems to thrive which also improves sustainability. Water is managed better in urban areas with the presence of trees, as they reduce the risk of flooding by increasing infiltration and reducing water runoff.

Trees are known to have a positive effect on mental and physical health, and in urban areas it is crucial to harness these benefits.

In economic terms, trees can increase property values, reduce energy costs by providing shade and windbreaks, and attract tourists and shoppers to areas with tree-lined streets as they can make an area more attractive.

Why is it important to protect tree roots?

Nutrient and water uptake

Roots absorb water and essential nutrients from the soil, which are necessary for the tree's growth and survival. Damage to roots can affect a tree's ability to absorb these resources, leading to stunted growth, reduced vigor, and increased susceptibility to pests and diseases.

Stability and anchorage

Roots provide stability and anchorage to trees, preventing them from falling over during high winds or heavy rain. Damage to roots can weaken the tree's stability, making it more susceptible to uprooting.

Soil structure and health

Tree roots help maintain the soil structure by preventing erosion, promoting aeration, and improving soil fertility. Damage to roots can alter the soil structure, leading to reduced soil fertility, compaction, and erosion.

Ecosystem benefits

Trees provide numerous environmental benefits, such as carbon sequestration, air purification, and habitat creation for wildlife. Damage to roots can affect these benefits, leading to reduced ecosystem services.
