Premium Free-Draining Subsoil

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 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 a saturated hydraulic conductivity of 327mm/hr.

This subsoil complies with the British Standard for Subsoil (BS8601:2013), except for the high sand content. This non-compliance is considered minor, provided your project requires a free-draining subsoil.

If you need a faster draining subsoil, you might like to consider a product from our range of Washed Sands
