Premium SS Subsoil
• A Wide Range of General Landscaping Uses
• Alkaline Loving Plants, Trees & Shrubs
A free draining subsoil that largely conforms to the British Standard for Subsoil (BS8601:2013) table 1 Multipurpose Subsoil. Our SS Subsoil is a strongly alkaline subsoil with a pH of 8.4, making this subsoil ideal for general landscaping purposes where a high alkaline soil is preferred.
Our Premium SS Subsoil is best described as a strongly alkaline, non-saline sand with a single grain structure, high drainage rate and low stone content. Consisting of a light sandy texture, with a predominance of medium sand (0.25-0.50mm) and coarse sand (0.50-1.0mm), this sand texture has a high saturated conductivity of 135mm/hr, which is ideal where a free-draining subsoil with a lower moisture retention is preferred. Please note that the particle size distribution falls slightly outside the range indicated in BS8601:2013 – Figure 1, on account of the high sand content.
