For those of you who have filled poly systems, can you tell me if you have filled them over the entire surface area gradually, or in one area and then gradually expanded this area? Im thinking of the filling process and wondering if I have to put a one foot "hurdle" under the bag, a "baffle" of sorts, and move this gradually along so as to concentrate the filling in one place? Ideas, suggestions and comments welcome as usual.. thanks gentlemen... -- Mike Barnett-Bischof, Managing Director. BARNETECH Industrial Consultants Ltd. "For Eco-LOGICAL Solutions !"
