And yet another obnoxious opinion from me: If you are building a trench for a french drain, and you pack the bottom, you don't pack the sides. Therefore, water can still seep to the edges - although it will be slower. And clay soils will make a difference in that there will be a near zero soaking into the soils - although they are more likely to plug.

Basically, I need to prevent surface water hitting the wall and penetrating, and more importantly, stop the ground moisture coming up the wall (through the capillary action).
I have been told one solution is to dig a French Drain along the wall, by cutting the concrete slab.
Does anyone, especially "paul wheaton", "Kabir424" or "40 years in const." can advise me if this is the soloution? Thanks.
