       Hmm, not very good advice. The purpose of the rebar is to hold the 
concrete together. If it sticks out into the air or the soil, it WILL rust 
and the rust will migrate along the whole piece of rebar. Eventually all 
there will be is totally rusted-out rebar which gives no strength to the 
concrete and the concrete will probably start cracking resulting in 
structural problems.  

     His method wouldn't pass ANY inspection these days.
