Due to their structure as hard rocks, diabases are primarily used in structural applications, especially in outdoor settings such as parks, gardens, squares, walkways, pedestrianized city boulevards, overpasses and underpasses, bridge claddings, as well as wall and swimming pool floor coverings. Diabases are suitable for all surface treatments due to their structure. The most commonly preferred surface treatments are polishing, honing, sandblasting, sandblasting + patina, and brushed finishes.
