This material is used to fill holes in and around ponds and dams. Just pour in the 1/4"- 3/8" chips in the hole. It will expand with water and help stop the leaks in farm ponds. The brand name is Cetco Puregold medium chips, a bentonite product. Located 10 miles east of Decatur. 50 lb bags, $30 bag. I have about 20 bags available.
