The Water-Holding Capacity of Perlite

The natural size and unique structure of expanded perlite makes an ideal framework to hold water. Perlite holds water in one of three ways: in between individual grains, in channels leading to the cores ofthe grains and on the highly irregular surfaces of each particle (Fig. 1). The surface of perlite is made up of the outer convex shells of …

Perlite: The Mineral for Healthy Plants

Expanded perlite provides space for both air and water within a soil mix. Natural soil is made up of four components: minerals, organic material, air, and water. When buying plants for your home or garden they should be grown in soil containing all of these elements. The unique characteristics of expanded perlite qualify it as one of the most desirable …

Roof Gardens that are Gentle on the Roof

Lightweight Solutions to Weighty Problems The current, eco-friendly trend of designing commercial buildings with rooftop gardens has put a premium on the use of expanded, volcanic perlite in making lightweight soils for these structures.
