Lightweight Expanded Clay Aggregates or LECA®LWA are granules of fired clay, used in construction and horticulture.

LECA®LWA is made by pelletising and firing selected clay in a rotary kiln at a very high temperature. As it is fired, the organic compounds in the clay vaporise 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 good 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.

By virtue of being lighter than normal aggregates clay granules are easier to transport and handle and are frequently used by sports and recreation contractors for drainage and back-filling to natural stone walls and concrete structures.

Expanded clay pellets are used as a substrate in hydroculture / 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.

Filtration and purification of wastewater and water for fish farms.

Insulation especially under flooring on roofs in particular for "Green Roofing Systems".

Heat proofing in kilns, stoves and pizza ovens.

Lightweight Concrete: As a component in non-structural lightweight concrete mix suitable for fake rocks, theatre props, and lightweight repairs.
