Sikaplan-130 PE polyethylene sheet membrane

A 0.30 mm low-density polyethylene (LDPE) sheet, flexible and chemically inert, laid loose under concrete slabs or between layers in flooring systems. It works as a moisture barrier or separation layer under ground-supported floor slabs, floating or unbonded screeds, and beneath insulation boards or drainage layers. Install by unrolling and overlapping the sheets.
