I think it's the brand because I've been switching to Fresh Step slowly, a box at a time and I have no problems with a layer of cement on the bottom with it but I did with Tidy Cat no matter how deep the litter was. I tried Exquisicat from PetsMart and although entirely too dusty it doesn't make that cement layer on the bottom either.
