Marble and granite are both beautiful, highly sought-after surfacing materials. But each one does have its own attributes. Weighing the pros and cons before deciding on one or the other for your surfacing project is important.
Though both are natural and quarried from the earth, they possess very different properties. The biggest difference between granite and marble is their porosity. Basically, marble is softer and more porous than granite with few exceptions like marble from Danby, VT.
Marble like Imperial Danby from Vermont is one of those types which are very solid. Granite, whose crystalline structure makes it more resistant to abrasion, staining, and discoloration, is in fact, the strongest of all natural stones.
