pouring a slab foundation on top of existing 4 inch concrete patio.
code calls for 2 inches of sand on top of 10 mil visqueen.what do you
guys think? should i just roughen it up and pour on top? Visqueen is
there as a vapor barrier.

Step one. Follow the code

Step two, if you don't like the code, see step #1.

I don't know about you, but I would want to know a lot more about what
is under that patio slab before I used it as any part of a foundation for
anything more than a dog house.
