Why is Expanded Clay Aggregate (ECA ®) a preferred aggregate for slab strengthening?

Expanded Clay Aggregate (ECA ®) is perfect for slab strengthening projects. Whether you are building a new structure and need to build a strong and functional slab, or you are adding additional floors to an existing building and must strengthen the existing slab, ECA ® can be used to add strength and support an increased live load – with the addition of minimal weight to the structure. It can be used both to support existing slabs and to create new slabs. The unique, hollow structure of ECA ® allows it to provide an extremely high strength-to-weight ratio, making it ideal for lightweight construction and slab strengthening.
