Properties of Gray Granite
Gray granite, like other types of granite, has significant properties that have made it widely used.
High strength, durability, very low porosity, very low water absorption and low compressive and abrasion resistance are some of these features.
Due to these properties, gray granite can be applied inside and outside the building. Can be installed inside the building in the kitchen, bathroom and toilet and hall. It can also be used for outdoor spaces, including facades. Of course, due to low porosity and high weight, it is better not to use it in the exterior. Travertine stones are definitely a better option in this case.
