Our local home improvement stores, Home Depot, sell the perf pipe pre-socked. I need to do some underdrains/curtain drains/french drains/farm tiles whatever you want to call them. I am an engineer and have seen several ways to do it. It seems that rock and perf pipe without a filter is the traditional way to do it. We have had success in the city with a socked pipe and sand to the surface. It seems the sand is less likely to clog with sediment than the rock.

What is the general consensus about pipe, fabric, and backfill in clay type soils. The pipe will be 4 or 6 inch perf pipe.
