Xaraashka bulshada, iyo injineelada la xoojiyey, si xoogan loo xoojiyo xoojinta derbiyada, derbiga, derbiga, derbiga, qaab dhismeedka grid. Waxay leedahay furitaanno waaweyn oo kor u qaadaya is-dhexgalka sheyga buuxinta.
Polyester Gerogrid Guurka Guud ee loo yaqaan 'POLYER GRID' ayaa lagu yaqaanaa lymser-ka xoogga badan ee polyms ah sida cabirrada molmoolka ee sare iyo xoogga laga bilaabo 20kn / m (nooca biaxial), 1kn / m (nooca aan lahayn). Grid Grid ayaa loo abuuray iyada oo loo marayo is dhexgalka, sida caadiga ah xagal qumman, laba ama in ka badan oo yar yar ama xog-ururin. Dibedda derbiga ah ee loo yaqaan 'Pet Grid' ayaa lagu daboolaa polymer ama walxaha maandooriyaha ah ee loogu talagalay UV, aashito, iska caabbinta alkali waxayna ka hortagtaa bio - burburka. Waxaa sidoo kale loo samayn karaa sidii caabbinta dabka.
