Please explain the use of expanded clay aggregate or eca in construction of lightened embankments and fills

In some areas, a traditional embankment may be either impractical or dangerous. Most commonly, this is true in areas where the soil dynamics are not ideal, and the underlying earth may be prone to shifting, which could cause catastrophic embankment or fill failure.

Using an Expanded Clay Aggregate (ECA ®) and a granular mix of soil can address this issue. ECA ® is extremely light compared to most fill soil. However, it’s still very strong and it has incredible moisture-resistance and drainage properties, which allows for the construction of extremely strong embankments and fills, without the risk of overloading the underlying soil.
