spoke with contractor regarding your direction for drain(thanks)He seems to feel that a layer of some sort of porous garden cloth on top of sand will be necessary. |
I think it depends upon what you plan to do with the area after installing the drain. If the sand is well packed it will remain on top of the gravel rather than disappearing down into it. If you lay sod or seed grass over the sand, it will be stable because the roots will knit it together. The problem with laying weed block or Remay over the sand is you'll need to cut holes in order to plant in the area. If your plan is to install the drain and hide it by covering it with bark or decorative rock, then yes, a landscape cloth is a good idea. Hope your project turns out well! |
