Yes, Expanded Clay Aggregate or ECA ® used for Lightweight screeds and substrates.
Due to its strength, lightweight, and affordable price, Expanded Clay Aggregate (ECA ®) is an ideal choice for screeds and substrates, particularly in buildings which require lightweight construction.
ECA ® uses a unique construction that incorporates a honeycomb structure, leading to a much lower weight and higher durability, compared to traditional concrete. Additionally, ECA ® is moisture-impermeable and has high thermal insulation properties.
Whether you plan on leaving the screed and substrate unfinished, or finishing it, and floating a smooth surface, ECA ® is an affordable construction material which is ideal for all building projects which require screeds and substrates.
