Hi Zane, These are Belgian cobbles, but not considered 'blocks' because of the type of stone and size. They're a very unique antique reclaimed cobble originally used in pedestrian areas, so they're more flat than typical reclaimed cobbles. We call them "Historic Sidewalk Cobble". They are approximately 5 to 6" square, by 2: to 4" high. Note the height varies. For a patio or walkway, setting on sand is fine. For a driveway they require a concrete base. On our Houzz profile there are many photos of projects using HIstoric Sidewalk Cobble.

We have two websites, this one is dedicated to our imported reclaimed cobblestone collection: https://www.historiceuropeancobblestone.com/ where you will find more information on this particular type of cobble. Or give me a call to discuss further!

Yes we are the importers and sell directly anywhere in the USA. However, there are constraints based on quantity for anything less than a full container/truckload. Please tell me approximately, the square footage you need? And, is it being set on sand or concrete?
