As it flooded a year a ago, I put in a basic French drain across the front of my workshop. Just stone, no pipe or liner. It did the job, but it's now silted up. I've dug it out again and am now ready to do a better job.
It's only 9ft. I just want to fill it with stone, no pipe. What's the best liner (if any?) And where best to buy? (I've looked at the Drainage Superstore website, but don't really know what I'm looking at TBH).
I tried a selection of supposedly permeable weed blankets but they aren't water permeable at all!
