The cinders I scavenged a couple of days ago didn't go nearly as far in the leach trench as I hoped, which means I'm quickly down to Plan B - sift pebbles.
By wildest luck the dirt I dug out of the trench isn't exactly a pebble-rich environment, but it's close to the trench so that's what we sifted today. Ah, well.
And that's gonna be the plan for a while. Lots of dirt to sift. This part of the project is likely to go on for quite some time, alas.
In the old days they used to put a layer of tar paper on top of the drain rock to keep it from filling up with dirt sifting down through it.
ReplyDeleteA couple layers of landscape fabric would probably work as well.
