Columbia Slate Patio Stone

The most attractive patios and walkways feature eye-catching colors and textures to invite people to gather upon their surface. Our Columbia Slate patio stones have a rippled surface mimicking the irregularities found in natural stone and can be placed in various design patterns to create inviting outdoor living areas.

Columbia Slate patio stones come in three sizes. You can use one size or combine sizes to create the look you want.

Columbia Slate patio stones are not suitable for vehicular traffic.

Columbia Slate patio stones are available for online purchase through the Mutual Materials Online Store.
