LECA Block
  • The porous micro-surface texture and interior porous structure of ECA resist clogging and provides superior aeration that promotes growth of delicate, fine root systems.
  • Since most soils consist of solid particles, water and air, it is necessary to maintain a careful balance.
  • A good soil profile is approximately 25% water, 25% air and 50% solid particulate matter.
  • However, when soils are compacted, an imbalance occurs and water and air are squeezed out.
  • The most important result of compacted soil is decomposition or putrefaction of root.
  • Expanded clay does not need to be re-applied year after year.
  • With ECA you can avoid compact or solid condition.

  • Generally, agriculture is done by two methods:
    • Conventional method - where natural soil is been used.
    • Modern method - where Expanded clay aggregate is used either with soil or individually.
  • Modern method in agriculture includes:
    • Horticulture
    • Hydroculture / Hydroponics
    • Plants In Greenhouse Containers

  • It improves the physical characteristics of these classic substrates for cutting production, for the growth of hothouse plants, for the growth of plants for flower borders, etc.
  • ECA has also been used in mixtures with mineral soil to improve the soil structure of nurseries.
  • ECA has other quality improvement such as following:
    • Increase air space for healthier root development
    • Reduce compaction of soil and Increase soil porosity
    • Reduce of sweet soil weight
    • Reduce labour cost through more efficient watering
    • Increase profits with quicker crop turnover and higher plant quality

  • ECA is pH neutral, is not compact and is reusable, making the product highly recommended and good for the environment.
  • ECA expanded clay is used as a direct replacement for soil, mainly in hydroculture and hydroponic systems.
  • ECA allows the system to be stable in form and structure, while allowing excess liquid to be absorbed.
  • Hydroponic cultivation with ECA is what is called a closed system.
  • Expanded clay is inert, so the plants’ nutrition depends on providing a nutritional solution.
  • ECA , also supports plants, since its regular shape results in better aeration and lower moisture retention.
  • Another great advantage of ECA expanded clay in this system, is that it is very light and easy to manage.

  • The soil in the containers is subject in time to pressing due to its weight and the water.
  • Adding ECA significantly and permanently improves its porosity features for air and drainage, thus avoiding the suffocation of the roots and enhancing the overall result.
  • Furthermore, the soil, with 20-30% of ECA, reduces the excessive weight of the containers, yet assuring the necessary stability.
  • ECA is also useful when moving plants from the container to the customer's garden.
  • A layer of ECA on the bottom of the hole assures drainage and the right level of humidity so the plants take root better.

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. Rivashaa Eco Design Solutions Private Limited has already been created a niche for itself on quality Lightweight expanded clay aggregate (LECA) and Expanded Clay Aggregate (ECA) product, on time supply and guiding customers on effective usage of Expanded Clay Aggregate (ECA) or Lightweight expanded clay aggregate (LECA) for best results. Expanded Clay Aggregate are preferred light weight aggregate used in place of conventional Charcoal, Coco peat, Diatomaceous earth, Growstones, Lavarock, Mineral wool, Perlite, Pumice, Rice hulls, Sand, Vermiculite and Wood fiber, Construction, Ceramic
