You must have been reading my mind! I was shopping around for a slab-edge dimple product like you suggest. The last thing I want to do is get the I am looking at ECP Water Channel Draim Board
. There is a very small amount of dampness that is accumulating on one section of footing right now so I definitely want to provide some sort of path for water pass through to get to the under-slab drain.
Thanks on the cleanout tip. I'll go with the SDR-35 cleanout.
