Ko te polyLock mo te whakaurunga Geomembrane he tohu HDPE pakari, he roa ka taea te maka ki roto i te waahi, ki te whakauru ranei ki roto i te raima maku, ka waiho te mata fehokotaki kia kitea i te otinga o te whakaritenga raima. Ko te whakaurunga o nga maihao punga e whakarato ana i te punga miihini kaha nui ki te raima. Ina whakauruhia me te whakamahi tika me te geomembrane, ka whakaratohia e te polyLock he arai tino pai ki te pakaru. Koinei te punaha punga miihini tino whai hua me te ohaoha mo te HDPE.
