Big River Industries is the nation’s largest producer of HydRocks, a lightweight expanded clay aggregate perfect for green roofs. In a rotary kiln, selectively mined clay is fired at temperatures of approximately 2000° F, producing a lightweight, ceramic aggregate. The aggregate is then processed to precise gradations, resulting in a high-quality, lightweight compound that is inert, durable and tough.
At nearly half the weight of common soils, this all-natural, eco-friendly, non-degradable aggregate can be mixed as a soil enhancer to provide the following benefits to green roofs:
- Reduces water usage
- Retains moisture during dry periods
- Reduces water run-off
- Improves moisture retention
- Provides sufficient draining
- Promotes healthy root structures
- Reduces nutrient loss
- Encourages aeration
- Prevents soil compaction
One high-level green roof design that implemented HydRocks is Chicago City Hall. The story behind how the developers and planners created this premium green roof structure and the pivotal role Big River Industries played in the project’s success make for a fascinating case-study.
