Additions for Soil

As soils are site specific, TerrAffix Soil Solutions provide several additions that can further improve conditions for soil function and plant growth. For more complex sites we can provide bespoke solutions based on soil analysis to ensure that the best-fit solution for your site is achieved.

We provide additional products that support vegetation establishment, including fertiliser, slow-release inorganic nutrients, trace elements, inoculents and biochars:

  • Mycorrhizae – a biological addition that supports the plant to access inorganic nutrients from within the soil environment;
  • Liming agent – provides a source of calcium carbonate, calcium phosphate and micronutrients for use on sites with acidified soil;
  • Fertiliser – an organic, readily available source of NPK (8:4:2) derived from mycelial fungi;
  • Amended biochar – provides opportunities for nutrient exchange, water retention and microbiological activity;
  • Tackifier – a product for use on extreme slopes where additional temporary adhesion may be required.


TerrAffix-HydraMulch is a 100% natural hydraulically applied erosion control system for extreme slopes and embankments, land reclamation and rough or polluted ground.

We supply and apply all our products.

The recycled eco-fibre blend of TerrAffix-HydraMulch establishes germination and promotes vegetation growth for permanent erosion control far more quickly than standard hydroseeding or Rolled Erosion Control Products.

TerrAffix-HydraMulch can reduce topsoil depth and can remove the requirement for any topsoil at all if used in conjunction with TerrAffix-Hydrasoil over a suitable substrate.


TerrAffix-HydraSoil is a hydraulically applied first stage biotic soil media system for poor steeper roadside or heavily polluted mining slopes where site access is limited.

We supply and apply all our products.

It is a topsoil replacement system made from recycled fibres which rapidly establishes vegetation in order to prevent erosion.

TerrAffix systems also prevent pollution from mobilising in soils and therefore mitigate against wider environmental pollution.
