Thanks D&C and Brewman. I bought this house 5 years ago, and the previous owners had gone wild with the red stone landscaping, all with no longer effective weed barrier. Front, back, sides, none inside yet, as far as I know. Anyway, I got more of it than I can possibly use, except to sell it on ebay. The crete guy said he could use it since it is just piled on a tarp out back. I am a CPA and an auditor by trade, and therefore question too many things in life. Drives my wife nuts. Once the crete is in, the tub can come in a week. Enough already, I need to get back to work..........
