I know this is a played out question from some of my searching but I need to know if there are any benefits at all from putting pavers over concrete. I have a new maintenance customer that has a large patio being installed this year. The installer is a large company in town that does a lot of these. I am not trying to get the contract I just don't want the customer to get screwed. This company has said that they are going to pour concrete as a base and then mortar the 2 outside border rows. It does not sound like they are going to mortar set the pavers. It sounds like they are going to use a sand leveling base between the concrete and the pavers. This is being sold as better and longer lasting.
