LDPE 0.5mm is a geosynthetic lilner made of low density polyethylene. The membrane has a lower density than HDPE and thus does not have the same high chemical resistance. LDPE is also softer and more compliant than HDPE. LDPE 0.5mm can be used as surface protection against damage caused by dirt and during transport as well as assembly and storage. The membrane can be applied in installations such as garden ponds and dense infiltration beds.
