Cats do not always bury their excrement in my experience. I use a product called " Silent Roar" which seems to work effectively in stopping them defecating in the garden but you have to "top it up" every 4 or 5 months. It is eau de lion and available from garden centres.
My ballast is 4 horticultural grit, 1 sharpe sand, 1 cement mixed with water and applied. No cat problems with that.
