It's not Faux Stone, It's Abby Rock.

The key component in Abby Rock is solid polymer substrate (SPS) produced from a recycled composite by-product obtained through innovative reclamation and containment processes to ensure the integrity of the material. The Abby Rock Vista line of products provides all the quality and beauty of natural stone creations in pre-manufactured structures, ready to set into place and enjoy.

Vista by Abby Rock is the closest thing to a natural, custom look...never mistaken as imitation. Abby Rock is a proprietary stone-based material that is precast into products and surfaces that duplicate the elegance, beauty and value of handcrafted stone work – without the mason. For custom projects like walls, accent areas or cladding — choose Abby Rock ProVeneer to achieve a touch and feel that is indistinguishable from natural stone – but with distinct advantages. It's easier to install, much more durable than faux stone, and it costs less to install.
