About ECA

Rivashaa Eco Design Solutions Private Ltd. proudly brings to you a revolutionary Make In India product called Lightweight Expanded Clay Aggregate, also known as ECA or LECA. Also, Rivashaa Eco Design Solutions Private Ltd is the first to introduce a MAKE IN INDIA Lightweight Expanded Clay Aggregate (ECA), ECA Construction Blocks, ECA Thermal Insulation Mortar, ECA Thermal Insulation flooring blocks, ECA Lightweight construction wall panels and ECA Thermal Insulation Tiles to India.

Lightweight Expanded Clay Aggregate, also known as ECA or LECA is a unique Green Construction Material which is 100% Natural and Inert light weight aggregate.

ECA is a round pellet structure produced by firing natural clay at temperature of 1200°C. The result is a hard, honeycombed structure of interconnecting voids within the aggregate. The particles formed are round in shape and generally range in size ranging from 0-30mm. These are processed to the required grading, depending on the versatile applications.

Expanded Clay Aggregate (ECA) are up to 6 times lighter than traditional aggregates. They are
