Premium Free Draining Subsoil (Y)

SUITABLE FOR:
• Free Draining Subsoil
• Compaction Resistant Subsoil
• A Wide Range of General Landscaping Uses
• Trees, Shrubs and Amenity Grass where a free-draining subsoil is required

Our Premium Free Draining Subsoil is best described as a non-saline, stone free sand with a narrow particle size distribution. The very free-draining nature of this subsoil is confirmed by the predominance of medium sand (0.25-0.50mm) and a lower proportion of coarse sand (0.50-1.0mm) along with the saturated hydraulic conductivity of 570mm/hr.

This Subsoil complies with the British Standard for Subsoil (BS8601:2013) apart from the high sand content. This non-compliance is viewed as minor provided the landscape application proposed for this subsoil requires a free-draining subsoil.
