Dsaundry the recipe can be modified a lot its really whatever looks best i am using 2 part sand 2-cement 2-salt 1-Oyster shell. Some people dont use sand others dont use oyster shell. I am not sure what i paid per pound as i got the cement free from a fellow canreefer (thanks Rob) and the sand i picked up pretty cheap.

BC Mosaic the cement is white portland from Rona. The salt i am using is a mix of small salt used for de-icing the driveway and large chunks of water softening salt. Both types of salt are very resistant to disolving, almost too resistant. There are several methods of molding the rock most use sand to create molds and build on it like you said.
