gradient on intersection

hello everyone
i would really appreciate some help on this one as its driving me crazy

vray 1 47 03
irmap(-5 , -3) and qmc
qmc sampler - adaptive amount 0.9
noise threshold 0.01
everything else default apart from dark multiplier at 1.4
dual xeon 3.2 , 2gb Ram 3GB SWITCH enabled ,win xp
max 7 sp1
any idea on how to make the gradient disappear
the building geometry is buried in the ground object.
tried with higher noise threshold but the problem remains.
the camera used has a cam correction modifier by the way.

any ideas are welcome
kind regards
