Lightweight Expanded Clay Aggregates or LECA® are granules of fired clay, used in construction and horticulture, where the product is often referred to as Hydroleca.

LECA®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® 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 concrete structures.

Expanded clay pellets are used as a substrate in hydroculture / hydroponics, and blended with other growing media to improve drainage 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". LECA® can be used with cement to make a lightweight concrete mix suitable for fake rocks, theatre props and lightweight repairs.
Heat proofing In kilns, stoves and ovens.
