Welcome to Comus Stone

Comus offers a unique range of stone products for architectural, horticultural, and landscape use.  We offer dolomitic limestone boulders, aggregates, and veneer, as well as crushed shale (stone dust), shale steppers and pavers, and expanded shale for soil amendment and green-roof applications.  We can customize all of our products to suit your individual project requirements. 

Our stone products are locally quarried in Maryland, and are a by-product of the cement industry.  By reclaiming this material, no additional mining is required to produce the finished product, creating less overall environmental impact.

Beautiful...Naturally
