I-plastic flat geonet iwumkhiqizo wesakhiwo sokunetha esiyisicaba owenziwe nge-HDPE polymer resin noma enye inhlaka ye-polymer nezinye izithasiselo ezihlanganisa i-anti-UV ejenti. Isakhiwo senetha singaba isikwele, i-hexagonal nedayimane. Ukuze kuqiniswe isisekelo, okokusebenza okuyimbudumbudu kungakhiywa ngezakhiwo zepulasitiki ze-geonet bese kungakha i-planare ezinzile ukugwema ukucwila kwento ewumbudumbudu kanye nokucindezela ukulayisha okuqondile. Ezimweni ezingezinhle zendawo, izingqimba ezimbalwa zama-geonets ayisicaba zingasetshenziswa.
