About LECA

Whether doing large-scale or small-scale construction projects, in order to make the building process cost-efficient and run more smoothly, building materials need to be sustainable, easy to handle, easy to transport and flexible to work with Leca® LWA or Leca® Blocks are exactly this.
While Leca® LWA (Light Weight Aggregate) is a simple product, our solutions are innovative. Alone, it is one single expanded clay pellet, but combining the pellets into an aggregate, possibilities become numerous – whether it is laying the foundation for construction, building roads and walls, or developing drainage solutions. The simplicity of the product makes it extremely flexible in the construction process. We have been around for a long time, so we know that our products work – and they last.
With a local presence in more than 12 European countries, we continue to develop and innovate ourselves looking for new partnerships and business models that propel Leca International, our partners and the environment forward.
