I will be laying 24x30 patio stones  (aprox 10x20feet).    I am looking for
any advice or tips you have relating to this topic.    My house is 33 years
old.
Over this time the earth has developed a sight incline towards the house
(aprox 1.5
inches over 10ft).   We have weeping tiles and did not have any water
problems yet.  We bought
this house 4 months ago, but there is no evidence at all of leak problems.

What I am thinking of doing is killing the grass in that area.  Then add
some dirt on top of the grass to give it a slight slope away from the house.
Then I
want to add � inch of sand to level the ground.  On top of that, I would lay
a roll of
landscape  fabric for weed control.   Lastly lay the rock and then add some
sand
in-between the cracks.   Some one suggested adding salt to the sand for weed
control.
 I figured that the earth has settled enough in 33 year that I don't need to
put gravel.  My guess is I will need to add about 2" of dirt at the highest
point by the
house.

Those this sound good?  Any other advice?

btw.  The earth onder the grass is 50% sand.    Also, this patio will not be
 in high trafic area (just for a bbq and table).  I live in Ontario Canada.
What type of sand should I use (fine or coarse?).   I have plastic sheets,
but I am afraid that the water will not drain if I use it.    Also, should I
uproot the grass?
