Genuine and original LECA® LWA distributed prepacked in the UK by Specialist Aggregates

Lightweight Expanded Clay Aggregates or LECA® LWA are granules of fired clay.

LECA® LWA is made by pelletising and firing selected clays in a rotary kiln at a very high temperature. As it is fired, the organic compounds in the clay burn off forcing the pellets to expand and become honeycombed while the outside surface of each granule fuses to give a ceramic shell. The resulting granules are lightweight, and have a high resistance to crushing.

Being a natural product LECA® LWA 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 sound and thermal insulation properties.


Expanded clay pellets are pH neutral, and are porous, yet have the ability to store water. The gaps between the pellets provide good aeration for root systems.

Expanded clay pellets are used as a substrate in hydro-culture / hydroponics, and blended with other growing media to improve drainage and insulate roots from frost. They can also be spread as a top dressing (mulch) around plants to retain moisture and help prevent weed growth.
