Hi,

I am working on a french drain around the perimeter of my house, which on a downhilld slope. Lot of water is seeping into the crawlspace.

I now have a 3 foot deep trench dug, but it is 12-in which. I would like to reduce the wideth to 6-inch (put the dirt back) and fill the other 6-inch with a wall of drainage rocks.

Wondering about the best way to fill up the dirt, to reduce the tench width from 12x36 inches to 6x36 inches. I have a total of 70-feet trench length.

I was thinking of using "SILT-FENCE", put it in the trench, fill on one side with direct and the other with gravel.

Any suggestions would be appreciated. Can I put the "SILT FENCE" on the side of the water run-off. I saw a pre-made SILT Fence at Home Dept with stakes attached.

thx.
