Best way to lay this stone patio?
We just tore up an old patio that was here when we bought the place. We assumed that it was constructed of typical flagstone. This stone is HUGE! The large flat pieces (some nearly 3 feet across) are about 6 inches thick! All of the stone is this thick, none of it is thin like normal flagstone. This a ROCK patio!
Luckily we have a big Kubota tractor with a bucket and we've removed all of the stone, tamped the clay base and we're adding the sand. These big rocks are going to be difficult to level, what would be the best way to get them as level as possible?
Would you mortar between them, or just use sand? We were also thinking about using Polymeric Jointing Sand? Any advice on using that stuff?
