In the raised planter, how much soil can you put over the drain and geo textile fabric without having issues. I'm working on a 2ft concrete raised planter 70 ft long. I wan to be able do some planting over the drain. If drain is on the bottom I was thinking of 3-4 inches of rock, pipe on top of that and 3-4 inched of rock on top of pipe then wrap it. That' about 10 inches of drain which would leave 8 inches of soil over it. Would the 8 inches of soil over the fabric caused plugging issues down the road.
Sounds like you've got a solid design. The extra soil above is not really a problem. As long as the moisture will eventually have an outlet, that's all you need. Thanks for the question!
Thanks so much for getting back to me. On the French Drain portion of the pipe does it need a 1% slope ? I read somewhere where it can be almost level and hydrostatic pressure will push the water out.
@@goflyhighrc 1% is still recommended. Hydrostatic pressure is not inside the pipe itself - it is simply what forces water out of the surrounding soil and into the pipe. Once the water percolates up into the pipe through the holes, it's just running down a sloped, open drain pipe. Good luck on your project, and let us know how it goes!

I always found drilling a few weep holes in the wall with stones around it worked well.
Yes - depending on the situation that can be a quick fix!
