Cob: foundation ? why ?

[olivier Tallendier]

does cob house need really foundation ?

I have seen some house today directly build on the ground.
( i'm still in india )

if the foundation are made to protect the walls from humidity,
why not clean the ground, put a mix of stones and lime on the ground
( like a drain )
and directly build the wall on it ?
after to protect the wall from water why not put stones on the foot of the 
wall and dig a kind of drain all around the house ?


i have done a small drawing, i will send it if you ask me.
