Medium Coarse Washed Silica Sand (D)

Suitable for:
• Tree Pit Subsoil Layer
• Podium Landscapes
• Bioretention Systems
• Rain Gardens
• Subsoil Layer for Formal & High-Use Grass Lawns

Classed as a ‘medium coarse sand’ with a single grain structure and alkaline pH of 7.8, our Medium Coarse Washed Silica Sand (D) is ideal for a wide range of landscape applications. A brownish yellow in colour with a total sand content of 98% with 2% fines, this subsoil has a narrow particle size distribution dominated by a medium sand (0.25-0.50mm) and coarse sand (0.5-1.0mm) with smaller proportions of very coarse sand (1.0-2.0mm). This sand texture creates a free-draining subsoil offering good porosity and high permeability at 563mm/hr when in a compacted state.

This free draining, compact resistant subsoil is ideal for a wide range of landscape applications including planting larger, root-balled trees, podium landscapes, or formal/high-use grass lawns. Further uses include filter medium for bioretention systems and rain gardens (ref SuDS).
