Expanded Clay Aggregate (ECA), ECA Size, Uses

Uses of ECA


The product is also called as Leca Haydite or ex-clay. In Europe, LECA commenced in Denmark, Germany, Holland (Netherlands), UK and Middle East. There are several manufacturers and suppliers of Lightweight expanded clay aggregate (LECA) and Expanded Clay Aggregate (ECA) in the world. 

Common uses of ECA are in concrete blocks, concrete slabs, geotechnical fillings, lightweight concrete, water treatment, hydroponics, aquaponics and hydroculture. ECA or LECA is a versatile material, and is utilized in an increasing number of applications. In the construction industry, it is used extensively in the production of lightweight concrete, blocks and precast or in cast structural elements (panels, partitions, bricks and light tiles). 

ECA used in structural backfill against foundations, retaining walls, bridge abutments. ECA can drainage the surface water and groundwater to control ground water pressure. LECA grout can be used for flooring (finishing) and roofing with thermal and sound insulation. 

ECA or LECA is also used in water treatment facilities for the filtration and purification of municipal wastewater and drinking water as well as in other filtering processes, including those for dealing with industrial wastewater and fish farms. ECA has uses in agriculture and landscapes. It can alter soil mechanics. It is used as a growing medium in hydroponics systems, and blended with other growing mediums such as soil and peat to improve drainage, retain water during periods of drought, insulate roots during frost and provide roots with increased oxygen levels promoting very vigorous growth. 

ECA can be mixed with heavy soil to improve its aeration and drainage. ECA is useful for Landscaping, Petrochemicals – Oil and Gas, Roof Top Thermal Insulation, Sound or Acoustic Insulation, Roads and Bridges, Floating Bridges on Water Bodies, Floating Solar Power Plant or Panel, Landslide Prevention, Waterproofing, Outdoor Sports Courts, Railways & Metro Rail Projects, High Strength Structural Concrete, Precast Concrete Segments, Surface or Waste Water and Affluent Treatment and Water Conservation.
