Why is expanded clay aggregate preferred for installation and drainage for earth retaining walls ?

Expanded Clay Aggregate (ECA) is an extremely valuable building material when creating earth retaining walls. Retaining walls must be strong and lightweight, and be able to absorb moisture from the earth, and deal with regular temperature and moisture fluctuations. ECA can be used for all types of retaining walls, from gravity walls to piling walls, cantilever walls, and anchored walls.

It is strong, lightweight, and the perfect additive for concrete blocks that are to be used in any retaining wall installation. It also resists freezing, which is critical for retaining walls which may be exposed to cold temperatures and may otherwise crack or fail.
