My dad and I do a lot of projects around the house from making bathrooms to electrical and event decking. However, this is the first time we will attempt to make a patio and we have been arguing about the proper depth to dig. I say to go with 2" of base material and 2" sand beneth the 2.25" brick. However, he want to go with 1.5" of base material and 1" of sand for the 2.25" brick.
Should there be a limit to how thin the base material and sand should be?
