Inquiry (采购产品): Concrete Pond Sealer I have a concrete fish pond and a small concrete stream with a water fall running into the pond. The concrete stream has many stones cemented to the concrete base. The problem is both the pond and stream are leaking. It is 7 years old. Do you have anything to help me?? **** Hidden Message ***** Stephen Banko 20716 USA Company: None E-mail: huntersmb@aol.com **** Hidden Message ***** huntersmb@aol.com
