Ash filter material is a lightweight by-product of power generation, known for its excellent drainage properties. With a bulk density of 1.6m³ per tonne, it is significantly lighter than many traditional aggregates, making it ideal for use in soil mixes where weight, permeability, and structure matter.Its fine 7mm minus grading improves soil aeration and water movement, making it a practical solution for horticultural applications, rooftop gardens, drainage profiles, and other areas where reducing compaction while maintaining effective filtration is key.
