The Kelt Liscio is a lightweigt concrete brick with a top layer of natural stone. The baseconcrete brick has been made from a stable concrete, meaning that every brick has exactly the same dimensions. The top layer has been polished to create a shining surface that’s relative easy to clean. Seven different top layers are available as well as 15 sizes of brick. Other colours and sizes are available on request. The bricks can be laid with mortar or glue, to minimize the joints.
