Lithocrete is the result of a patented process in which materials and concrete are embedded and fully adhered to each other, resulting in dramatic concrete paving. Recycled materials, such as glass, are used in order to provide a wide range of colors not typically found in other paving options. Bright blues, yellows and reds are just some of the colors lithocrete produces. None of these glass aggregate colors will fade under sunlight. They naturally reflect light, resulting in less heat absorption.
