Batten strips may be used to attach the liner when other methods are not practical. With the rope hem above the batten strip, sandwich the liner between batten strip and tank wall at desired location. Drill through the strip, liner and wall. While making sure nothing shifts out of line, drive in anchor. Anchor each hole before moving to the next one. Continue to work your way around the tank until finished, then go back, checking anchors for tightness. We offer HDPE batten strips in 2” wide x ½” thick x 2’, 4’, 6’, or 8’ lengths.
