My backyard and side yard are covered with pavers. I need to install a French drain underneath the pavers. The drain will go along the back of the house and then along the side of the house. I will dig a trench for the drain then lay geo fabric in the trench then 2 inches of stone then the pipe and then cover the pipe with another 2 inches of stone. I will then wrap the fabric around these stones and pipe ("fabric roll"). My question is what do I put on top of the fabric roll and underneath the pavers? Do I add more stones on top of the fabric roll then sand and then the papers? Or do I add paver base on top of the fabric roll and then sand and then the pavers? Or do I put topsoil on top of the fabric roll then sand then the pavers? Looking at the layers from top to bottom, on top would be the pavers then underneath the pavers would be 1 inch of sand and again my question is what goes on and on top of the fabric roll that is holding the pipe and the stones and the sand? I know the sand layer is to be 1 inch deep. How deep will be anything else that goes between the sand and the fabric roll? Thanks for your help.
