Iplasitiki flat geonet yimveliso yesakhiwo senethi esisicaba esenziwe nge-HDPE polymer resin okanye enye i-polymer resin kunye nezinye izongezo ezibandakanya i-anti-UV agent. Isakhiwo somnatha sinokusikwere, i-hexagonal kunye nedayimane. Ukomelezwa kwesiseko, imathiriyeli yegranular inokutshixwa kunye nezakhiwo zeplastiki ze-geonet emva koko inokudala iplani ezinzileyo ukunqanda ukutshona kwezinto zegranular kunye nokucinezela ukulayisha ngokuthe nkqo. Kwiimeko ezimandundu zejografi, iileya ezininzi zee-geonets ezisicaba zingasetyenziswa.
