Concrete Creations manufactures concrete bird baths that are sold through retail outlets nationwide. The bird baths are made in a two-stage process. In the Forming Department, the concrete is poured into silicone molds where it is allowed to cure and set. Once set, the birdbaths are removed from the mold and sent to the Finishing Department where any imperfections are removed and the birdbaths are sprayed with a special sealant.

Information for the Forming Department for the month of May is provided below.
