Lapitec is made up of natural resources including clay, feldspar and other natural minerals and pigments. The manufacturing process applies 5,000PSI of pressure at 2200F degrees which sinters and fuses the particles together. This is a product that is long lasting and completely weather proof. Every slab is resistant to acids, alkalis, deep abrasions, fire, frost and is unaffected by UV rays. It is also resistant to graffiti. Lapitec® is produced with maximum respect for both people and the environment. It is completely inert, containing no resins or petroleum derivatives.
