Pumice Media
Pumice is a natural, lightweight volcanic aggregate with a porous structure and rounded particle shape. Pumice is extensively used in horticulture as a growing medium as it improves soil aeration, retains moisture and promotes root growth. As demand for green roof installations increases so does the use of pumice as a substrate in both the intensive and extensive systems. Reasons for this include:

• Improved soil aeration

• Moisture retention

• Long lifespan

• Thermal properties help insulate a building helping conserve energy

• Improves and controls drainage to avoid run off

• Promotes root growth

• Environmentally friendly

• Air quality improvement

• Noise reduction – acts as a sound barrier from industrial units below

• Habitat for wildlife

 

Our pumice aggregates 0-4mm and 4-16mm are recommended for use in this application.
