Washed Tree-Pit Subsoil (E)

SUITABLE FOR:
• Tree Pit Subsoil Layer
• Tree Planting Subsoil in Hard Landscapes
• Free-Draining, Compaction Resistant Subsoil
• Podium Landscapes and Formal/High Use Lawns
• SuDS Rain Gardens & SuDS Bio Retention Systems

Our Washed Tree-Pit Subsoil (E) 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 the saturated hydraulic conductivity of 621mm/hr.

This Subsoil is ideal for use as a Washed Tree Pit Subsoil and a wide range of landscape applications, including the planting of larger root-balled trees in both soft and hard landscape situations, podium schemes and formal/high-use grass lawns. Further uses include as a Subsoil for SuDS Rain Gardens and SuDS Bio Retention Systems.
