Sand and Gravel under Paver Patio or just Gravel?
We are putting in a 400 square foot patio and were planning to put in 4 inches of gravel (crusher) and 2 inches of sand under the 16 inch patio pavers. Then we were told by one of the stone/sand/mulch companies we spoke to that they don't think we need the sand and that when they do patios they never use the 2 inches of sand underneath--just 6 inches of gravel. I just wondered if anyone had heard this. I assume we will use the sand, but it would be cheaper not to use it.
