This type of surfacing material comprises thin, flat pieces of a fine-grained, foliated metamorphic rock known for its distinctive color. These pieces are specifically cut and shaped for use in outdoor flooring applications. For example, these materials are commonly installed to create patios, walkways, and driveways.
Their popularity stems from a combination of aesthetic appeal and functional properties. The inherent durability of the stone ensures resistance to weathering and wear, providing a long-lasting surface. Furthermore, the color variation within individual pieces offers a unique, natural look, contributing to the visual enhancement of outdoor spaces. Historically, similar materials have been employed for paving due to their availability and structural integrity.
