After being fired in a rotary kiln, the resulting material is cooled and conveyed for classification. During this phase of production, the aggregate is crushed and screened into different sizes.

The material is processed to very precise gradations, resulting in HydRocks®, a high-quality, lightweight compound that is inert, durable and tough. From there, HydRocks® is transported by rail, truck or barge to Garick blending and storage facilities located across the country. Garick distributes variations of the product which is used to sustain landscapes, build green roofs, and meet the varied needs of other horticultural applications.
