In terms of their physical and mechanical properties, the sandstones can be characterized by high values of bulk density, low absorption capacity and low total porosity, high abrasion resistance, high to very high values of strength properties and high fracture toughness. Due to their high compactness and strength, they can get relatively good polish, as one of few sandstones mined in the Czech Republic. However, in contrast to high quality of physical and mechanical properties of the Godula sandstones, degree of their durability in the case of exterior use is often very low.
