Description:
Pumice is a light weight bubbly volcanic glass - essentially a "solid rock foam".

Being a natural product pumice contains no harmful substances, it is inert with pH of around 8.0. Pumice is resistant to frost and chemicals, and will not break down in water. It is also non-combustible and has excellent sound and thermal insulation properties.

Product's Principal Application: Extensive Green Roofs and Horticulture:

Pumice is unique within the range of light weight aggregates. Whilst it has an open honeycomb structure similar to Lightweight Expanded Clay and Lytag® the individual pumice particles don't have an outer "ceramic" shell. This property allows pumice to readily absorb moisture during periods of rainfall, and importantly permits the moisture to be released during dry spells.

The free draining open structure of this pumice prevents water-logging and allows aeration and effective plant root development, making this is the product of choice for extensive green roofs.

This pumice may also be used for interior planting schemes in offices and shopping malls where its moisture retentive properties allow for less maintenance of free standing planters. This product is the lightweight substrate of choice for Bonsai growers.

Other Applications for this Product Include:

The production of lightweight concrete, being light weight and non-combustible it is especially useful for the creation of theme park, film and theatre sets.

Due to its colour we would not recommend this pumice in potpourri mixes.
