I'm having to reset the pavers along the side yard of our house after putting in a french drain and sump pump. The issue I have is that after I dig out all of the dirt to allow for the 4" of gravel, 1" of sand and 2" pavers, the dirt is below the fence and open to my neighbor's yard. I bought some pressure treated 2x6 to nail to the bottom of the current fence, but the old concrete from the previous fence is going to cause problems with the 2x6 fitting evenly.
In the attached photo, the string you see is level from the backyard concrete to the front gate. This is only about 3/4" above the bottom of the fence. In this photo, I haven't even dug down the 7" necessary, so the gap under the fence will be larger than what you see.
What do you suggest I use for a border, to contain the gravel, sand and pavers, so they don't gradually slide under the fence in to my neighbors yard?
Thanks in advance!
