I'm doing a french drain at the bottom of a slope. I lined the inside of trench with porous landscaping fabric then filled with 4" perforated pipe with sleeve and gravel.
I want to make a gravel path along the top of the drain.
My question is: Is it correct to put a layer of the porous fabric on top of the filled trench and add the gravel for the path onto the top of the fabric?
Or, will the water tend to run across the top of the fabric and not down into the drain? My reason for the fabric is to keep the drain as clean as possible but I don't want to defeat its primary function.
