Expanded Clay Aggregate (ECA) also known as Lightweight Expanded Clay Aggregate LECA is the right product for creating lightened draining layers for landscaping. The applications are Lawns, flower beds, planters, flower pots, plants, urban trees, top dressing, mulch patios, vertical gardens, hanging gardens, lightweight terrace gardens and all permaculture applications.

The porous, cellular nature of Expanded Clay Aggregate (ECA) helps manage air, water and solid particulate matter. It reduces compaction, increases the soil porosity and maintains the soil temperature. The gaps between the pellets provide good aeration for root systems. Expanded Clay Aggregate (ECA) limits excessive water retention and enhances drainage, which is an essential factor for the proper growth of roots and plants.

Expanded Clay Aggregate (ECA) does not release any salinity and does not change the Ph factor of the mixture. Expanded Clay Aggregate (ECA) does not change or decompose in time or due to humidity, it is even spread as top dressing on the pots/vases for aesthetics and dust prevention. ECA is an extremely light weight, strong and thermally insulating material. ECA is a better replacement for coco peat and conventional soil.
