Batten Detail Information
Geomembrane can be sealed to concrete structures using wood, aluminum, or stainless-steel batten. We recommend the use of butyl sealant between the PVC liner and the concrete.
Since PVC geomembrane is NOT crystalline, it is not necessary to use neoprene or rubber cushion with the batten. PVC liner does not stress crack, and therefore, clamping stress from the batten does not stress crack the PVC geomembrane as it sometimes does with HDPE.
Anchors can be powder-actuated fasteners such as Hilti or Ramset, with washers. Stainless-steel expansion anchors are also acceptable for connecting the batten to the concrete.
