Expanded Shale

This rock is made from shale that has been fired or cooked at very high temperatures. The heat causes the shale to expand creating a relatively strong but lightweight aggregate. The expanded shale is then screened to different sizes for use. Expanded shale helps physically loosen heavy soils and can help the soil hold moisture and nutrients. It is often combined with compost for use in rose beds and lightweight soils for green roofs.
