Boughton BLMP Multi-Purpose SuDs Soil - Urban Drainage System (SuDs) Soil

Boughton BLMP SuDs Soil is a multi-purpose blend of sand, PAS 100 green waste compost, crushed brick and coir, designed to support a range of intensive vegetation. This SuDs blend is designed to be free draining with good porosity, while maintaining a sufficient moisture level to support diverse plant life

Features and benefits:

• Supports a range of intensive vegitation.
• Supports planting schemes within urban environments where problems occur with water run off.
• Designed to be free draining with good porosity, while maintaining a sufficient moisture level to support diverse plant life.
• Boughton BLHP High Permeability Soil meets and exceeds all present G.R.O guidelines.
