What is Leca® LWA
Leca® LWA is a well-proven, high quality, efficient and durable lightweight aggregate suitable for a wide range of applicants in the construction sector. It is a sustainable construction material packed with properties that improve the economic, social and environmental performance of a building or infrastructure over its whole lifetime.
Our goal is to be part of the solution to a problem affecting the entire world - how do we guarantee a sustainable future? By investing in environmentally friendly forms of energy in our operations, we can reduce the use of fossil fuels. In accordance with life cycle thinking, our product is long-lasting, durable, safe and, above all, reusable in many ways.
Leca's 75-year history has grown thanks to the environmentally friendly and durable material, lightweight aggregate. Leca® LWA is made from domestic clay, which can be used almost limitlessly in construction. There is no concern about the availability of raw materials because there is enough clay obtained from nature. However, we are not ready as a company, and we are not stopping here.
Curbing climate change and adapting to it requires concrete change from the construction industry. The change is not easy, and not all the steps are clear yet, but the joint journey must start today. Everyone must do their part to ensure a sustainable future for all of us.
