It really depends on the color of granite & the thickness.
The quick answer is approx. 12-20 lbs per square foot.
The darker stones tend to be more dense & subsequently weigh more than lighter colored granite. Obviously 3 cm slabs will weigh more than 2 cm slabs.
So the average slab weight is usually between 700-1200 lbs.
Yes, it's heavy!

Yes, in almost all cases. Granite distributes it's weight across the cabinets. When we template we will let you know if we feel like your cabinets need to be reinforced. I've only had one client need to reinforce their cabinets for the granite, so it's pretty rare.
