Designa Schist is a unique product that's designed to assist those that love the natural beauty of real stone but don't have the time, resources or the skills to lay individual pieces of stone in a wall. In essence "Its real stone made simple" We carefully select the stone and assemble it into pre - formed modular units called Z bricks, T columns, Blocks or Panel veneers. Allowing contractors the luxury of a pre - formed stone building unit that is then mortared in place the same as a brick, block, or in the case of the panel adhered / plastered to a suitable waterproof substrate. This saves considerable construction time and reduces unsightly and dangerous mess on site. It also means that bricklayers or plasterer can install, instead of hard to find, expensive specialist sub trades. We offer three natural schist stones that closely match the NZ environment. They are.... Autumn Horizon, Alpine Sierra, and Black Mountain. Other stone colours and texture
