Hi, I'm new to this forum and was referred here from the watergardening forum...I've just built a 20 thousand gallon pond that leaks; not enough clay mixed with the sand is what I suspect and the pond borders on a dirt road that's shared by neighbors above me so I want a pond that's not going to blow out the road after saturating the walls...I'm in earthquake country and could probably live with the cracks but I'd rather find a good means of lining the pond...the rubber pond liner sounds flimsy. I recently discovered something called Road Oyl that's used as a substitute for asphalt paving on trails and bike paths made from pine pitch and other friendly stuff...anyone ever try it as a liner? Barry

Hi Barry check with Bend Tarp and Liner just up the road from you in Bend Oregon. They sell liner for about 30 cents a square ft. I used it on one of my Koi ponds and it worked out great. Should not be bad on shipping cost either it was reasonable to ship it to Alabama.
