Topsoiling refers to the application or placement of suitable turf growing media (soil and additives) required for the end use of the turf surface.

Why is it required?
• To regulate plant root depth, this in turn influences
  the plants ability to handle stress.
• Sports surfaces generally require 150mm to 300mm
  depth of topsoil for healthy turf.

• To add suitable growing media to the surface for the proposed turf type.
• To effectively shape the land for the required use and to provide run-off drainage.
• Some soils become contaminated by the construction process and need to be corrected.
• Some soils have reduced pore space, draining slowly and need to be corrected.
• Raising the playing surface from the surrounding land is sometimes required.

Considerations:
• The type of existing topsoil. Will it support the proposed turf and suit the intended sport or
  recreation?
• The depth of the existing topsoil. Will it support the proposed turf and suit the intended sport or
  recreation?
• Quality of existing soil. Does it have the necessary nutritional value to support the proposed turf?
• The type and depth of new topsoil required. What is required to suit the intended usage of the
  surface and how much?
• The compatibility of the existing soil with new topsoil required. Will they blend adequately?
• Drainage pattern of existing soil. Does it drain adequately? Does it fail to hold water appropriately
  for healthy turf growth?
• Is access to the site for Topsoiling available in the warmer months? This allows for better results.
