The CityStone series shares a generative architectural look in which pavement’s scale is defined by the joint pattern. Joints and surfaces conform to US Access Board ADA surface requirements. The CityStone units yield unlimited creative control with access to other modulating CityStone shapes, color and textures to satisfy the architectural design intent. Made of durable concrete with iron oxide pigments which helps prevent fading from extended UV exposure. Meets or exceeds applicable requirements of ASTM C936 – Standard Specification for Solid Concrete Interlocking Paving Units and ASTM C1782 – Standard Specification for Segmental Concrete Paving Slabs. Smooth surfaces and classical chamfers define each stone to create texture and visual structure with timeless appeal. Square shapes easily form stacked and runner bond patterns.
