Columbia Patio Series

The most attractive patios and walkways feature eye-catching colors and textures to invite people to gather upon their surface.

We offer two slab textures. Our Columbia Slate patio slabs have a rippled surface mimicking the unevenness found in natural stone. Columbia Smooth is a durable even surface.

Columbia patio slabs come in three sizes, you can use one size or combine sizes to create the look you want for your project. Its rectangular dimensions allow for the ultimate design versatility and its larger dimensions allow for less units per square foot.

Columbia patio slabs are not meant for vehicular applications.
