Lightweight expanded clay aggregate

1. Horticulture/Hydroponics Industry

growing media in flower and vegetable production
hydroponics substrate for interior landscaping
constituent for substrates for green roofs

Expanded clay granules are ideal for use in landscape gardening because they offer the following benefits:

stable structure, no decomposable constituents
light weight
large exterior and interior surfaces that facilitate water films to form
low salinity
Specific pH---clay pebble's pH value is between 6-7.

2. Insulation/Construction material/Lightweight aggregate concrete

Thermal Insulation
Sound Insulation
Fire resistance
Non-decomposability
Water absorption etc.

Usages: Loose cell filling, Roof insulation, Road Construction
Aggregates, Light weight aggregate concrete block etc.

3. Water treatment: Wastewater---Biofilter, Filtrations

For home wastewater treatment, Leca/Expanded clay aggregate can replace distance gravel in aerobatics filter manufacturing.

And also in anaerobic filters, the porous of Leca/Expanded Clay aggregate is a suitable environment for growth of useful bacteries.
