Subsoil

product-subsoilSubsoil consists of a variable mixture of small particles such as sand, silt and/or clay. It often lacks the organic matter and humus content of topsoil. Subsoil is an essential part of most soil profiles, providing moisture storage and reducing the rate of water run-off.

 

Introduced in 2013, the British Standard for Subsoil BS8601:2013 compliments the British Standard for Topsoil 3882:2007 and more recently, BS3882:2015 specification.

 

To adhere to the British Standard, a good certified subsoil should have

 

  • a high sand content (more that 65%)
  • over 50% of particles ranging in size from 0.25mm to 0.5mm
  • less than 2% organic matter

 

Ideally, the certified subsoil should be sourced from a single inert site and should be subject to testing for heavy metals and hydrocarbons to check for contaminants.

 

Soils and Stone have a number of high quality, certified, single source subsoils available .  These can be delivered in the loose via grab or tipper lorry.  Call one of the team today on 020 8546 3860 to discuss your project requirements.
