Light expanded clay aggregate is made in a rotary kiln, which is heated to a temperature of more than 1200°C. This causes the light-expanded clay aggregate to form oval or round balls, and the gases within the clay expand and create thousands of tiny air bubbles within each LECA, ECA® pellet.
Laterlite Plus light insulating aggregates are composed of a special expanded clay, characterised by a very low capillarity which allows it to be hydrophobic, not retain water and therefore remain dry.. Laterlite Plus insulating aggregates are also highly resistant and have all the typical properties of expanded clay aggregates, to which they add the particularity of being dry and hydrophobic.
