How to use vermiculite or perlite with existing lawn?

I just bought a house with a half dead lawn that requires lots of water. The soil here has lots of clay in it and as a result, doesn't hold water well and needs excessive watering to keep a lawn green. My neighbor lives on a hill and reseeded his whole yard only to have his back yard (uphill) die on him because all the water ran down hill. Question is, how would I use vermiculite, perlite, or anything else to help my lawn retain water? I have used Scott's turf builder in an attempt to spread the roots of the grass and my lawn looks 100% better, but it still needs lots of water :(

Answer:

Can have asbestos in it, especially in the past.
That stuff isn't very safe to breathe, same with perlite. It breaks into little flat flakes and dust that sticks to everything. I just imagine how messy it would be. Plus unless it's wet it's so light that a slight breeze could blow it around, and with static electicity it would be all over the cat's fur. But I'd be interested to see how it would actually work.
havent heard of that before, what is it?
