What is Leca®?
Leca® Flower is a genuine and original premium LECA® Lightweight Expanded Clay Aggregate manufactured by Leca(Saint Gobain) and exclusively distributed prepacked in 50ltr packs throughout the UK by Specialist Aggregates.

"Leca" granules are made by heating small beads made from selected clays in a furnace. At high temperature the organic compounds in the clay vaporise forcing the granule to expand and become honeycombed, while the outside surface fuses to a ceramic shell. The resulting granules are lightweight, porous and made sterile by the firing process.

Being a wholly natural material. expanded clay aggregate contains no harmful substances, it is inert with neutral pH, The granules are resistant to frost and chemicals, and will not break down in water. They are also non-combustible and have excellent insulation properties.

Density: Volume for volume, LECA®Flower is around a quarter of the weight of "normal" gravel having a dry bulk density of between 280 to 380kg/m3.

Water Absorption:
When saturated for at least 24 hours, LECA®Flower is likely to absorb approximately 30% by weight of water.
