ABSTRACT:
The invention provides surface elements such as tiles or panels consisting of a thin lamina of natural stone bonded to a backing consisting of a multicellular paper core material of substantially greater thickness than said lamina which at least on the side remote from the stone lamina has a skin of tenacious sheet material bonded thereto. The resultant composite element is extremely rigid, light and cheap to produce in comparison with solid stone and may be cut into any desired shape and used as a substitute for solid stone, but with the advantages of lightness, strength and low cost thus enabling such surface elements to be used for many purposes where the use of solid stone would be economically or practicably prohibitive.
