Simple ideas often last longer. LECA® LWA is basically made of freshly excavated clay, and produced through pre-treatment and high temperatures. 1m3 of fresh clay produces 5m3 of durable, natural aggregate. To be used in anything from flower pots to structural concrete bridge elements in harsh Northern seas. Focus on a resourcefully efficient production process is always maintained with the attention on producing as little waste as possible in the process. Strict quality control is in place in all our production plants to deliver high quality products with minimal environmental impact.
Leca ® Lightweight Aggregate (LWA) is a natural, unique and sustainable lightweight clay aggregate. LECA® LWA has remarkable properties which ensure its versatility for use in a vast number of structural and geotechnical applications. It is the only "all in one" aggregate solution for Architects and Civil Engineers to overcome problematic areas in construction and design. Thanks to its unique properties, expanded clay has a broad range of applications from residential housing, commercial building, structural and geotechnical build and horticultural and landscape projects and is emerging as an environmentally sustainable and more effective alternative to traditional heavyweight and cumbersome aggregate.
