thanks essup i'll try to figure that out. here are a couple pictures of the tube and riser. we allready have the tube welded up so all we have to do is drag it in place and begin covering it with dirt. we will weld the anti seep collars and riser on while we are adding dirt on. this can take a full day and we cant slow down that long. once we plug the middle of the pond we got to get done as quick as possible. we usually cover the pipe then start plugging the middle driving over the dirt covered pipe load after load for compaction.i say dirt it will be good clay from one end to the other of the pipe.
