Ezikhathini zamuva nje, izinhlangano zikaloliwe emhlabeni wonke ziye zaphendukela ekusebenziseni i-geosynthetics njengesixazululo esinezindleko eziphansi sokuzinzisa i-ballast. Kulo mbono, kuye kwenziwa ucwaningo olunzulu emhlabeni wonke ukuhlola ukusebenza kwe-ballast eqiniswe yi-geosynthetic ngaphansi kwezimo ezihlukahlukene zokulayisha. Leli phepha lihlola izinzuzo ezihlukahlukene imboni yezitimela engazithola ngenxa yokuqiniswa kwe-geosynthetic. Ukubuyekezwa kwezincwadi kuveza ukuthi i-geogrid ibopha ukusabalala kwe-ballast ehlangothini, inciphisa izinga lokuhlala mpo unomphela futhi inciphise ukuphuka kwezinhlayiyana. I-geogrid iphinde yatholwa ukunciphisa izinga lokucindezelwa kwe-volumetric ku-ballast. Ukuthuthukiswa kokusebenza sekukonke ngenxa ye-geogrid kubonwe njengomsebenzi wesici esibonakalayo esisebenza kahle (φ). Ngaphezu kwalokho, ucwaningo luphinde lwasungula indima eyengeziwe yama-geogrids ekwehliseni ukuhlaliswa kwethrekhi okuhlukile kanye nokunciphisa izingcindezi ezingeni le-subgrade. I-geosynthetics itholwe inenzuzo enkulu uma amathrekhi ahlala kuma-subgrades athambile. Ngaphezu kwalokho, izinzuzo ze-geosynthetics ekuqiniseni i-ballast zitholwe ziphakeme kakhulu uma zibekwe ngaphakathi kwe-ballast. Indawo ekahle yokubeka ye-geosynthetics ibikwe abacwaningi abaningana ukuthi icishe ibe ngu-200-250 mm ngaphansi kwe-slee soffit yokushona okujwayelekile kwe-ballast okungu-300-350 mm. Uphenyo oluningi lwezikimu kanye nezikimu zokuvuselela umkhondo kuphinde kwaqinisekisa indima ye-geosynthetics/geogrids ekuqiniseni amathrekhi ngaleyo ndlela kusize ekususeni imikhawulo eqinile yesivinini ebibekwe ngaphambili, kanye nokuthuthukisa isikhawu sesikhathi phakathi kokusebenza kokulungisa.
