Expanded Clay Pellets (LECA)

What are Expanded Clay Pellets (LECA)? Expanded Clay Pellets, often referred to as LECA (Lightweight Expanded Clay Aggregate), are lightweight, spherical pellets made from natural clay that has been expanded by high-temperature firing. This process creates a porous structure that provides excellent insulation properties and drainage capabilities. LECA is known for being environmentally friendly, as it is produced from natural raw materials and is fully recyclable. The primary applications of Expanded Clay Pellets span various industries, including horticulture, construction, and aquaculture. In horticulture, LECA is used as a growing medium for plants, enhancing aeration and moisture retention. In construction, it serves as lightweight aggregate in concrete and insulation materials. Additionally, LECA is utilized in aquaculture systems for filtration and as a substrate for aquatic plants. The growing demand for sustainable materials in construction and agriculture further cements the relevance of LECA in today's market.
