Hi, I could use some suggestions on a homeowner (me) drainage project.
I’ve got an older small house with a walk out basement that has always flooded when the water table rises. The grade slopes gently away from the house from the walk out entry and garage doors. I finally got smart and dug down to footing level course rock under it and now water runs out, down a ditch and over a bank and the cellar floods no more. When the table is up, usually in the spring or with these crazy rains we get these days, the flow it considerable. Never more than 12” wide and may 1” deep. I need to fill this in to get my driveway back, so the question is should I just make the ditch as low as the rock layer under the slab and footing, make it a foot wide, line it with fabric and fill it with 8” of 3” stone, cover with fabric and soil? Or should I creat a stone filled basin or sump next to the footing and run some 4” sch. 40 PVC
from that down the ditch to an lower exit point 40 feet away? Will the stone eventually fill in the PVC Or do I put some screen over the inlet end? Or some combo? attached are some photos.
Thanks for reading this, Larry
