Pumice Horticultural Gravel - A general purpose crushed and graded pumice. Use specifically as a substrate for extensive light weight green roofs and horticultural applications requiring good drainage together with moisture retention.


Pack Size: 8kg (Approx 12 Litres)

Stone Size: Approx. 6-14mm

Stone Density: Depending on moisture content stone density is approximately 700kg per m3 . The product is supplied with a natural moisture content.

Stone Colour: Beige / Light Brown

Coverage: 8kg of 10-14mm pumice will cover approximately 3/4m2 at 20mm depth.

Description:
Pumice is a 100% natural 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: 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 when watering or during periods of rainfall, and importantly permits the moisture to be released as planters dry out or 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 Bonsai growers.

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.

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.

Safety Information: This is a commercial / industrial product and not a toy.
