Ubunjiniyela besimanje bomphakathi buye waba nenguquko ethule emashumini amane eminyaka adlule, okubangelwa kakhulu ukwanda kwezinto ezithuthukisiwe ezenziwe ngabantu ezisebenza ngokuvumelana nomhlabathi, idwala, namanzi. Ezingqimeni zale nguquko kukhona umndeni wezinto ezaziwa ngokuthi ama-geosynthetics. Lezi zinto eziyisicaba, ezenziwe nge-polymeric, ziye zachaza kabusha indlela abunjiniyela abasondela ngayo ekuthuthukiseni umhlabathi, ukudonsa amanzi, ukuhlunga, nokugcina ezinhlobonhlobo zezinhlelo zengqalasizinda. Kusukela ezimotweni ezixhuma amadolobha kuye ezindongeni ezibambelela izintaba ezingamahlathi, ama-geosynthetics abe amathuluzi abalulekile ukuze kufezekiswe imiphumela ephephile, ehlala njalo, futhi engabizi kakhulu. Ukuncika okukhulayo kulezi zinto akuyona into edlula ngokushesha, kodwa kunalokho ukushintsha okuyisisekelo endleleni umkhakha wokwakha ubhekana nezinselelo ze-geotechnical, futhi ukuqonda izici zawo, imisebenzi, nezicelo kubalulekile kunoma yimuphi ochwepheshe ohilelekile ekuthuthukisweni kwengqalasizinda namuhla. Lesi sihloko sihlinzeka ngokuhlola okuphelele kwezinto eziyisisekelo ze-geosynthetics, sihlola izindima zazo ezahlukahlukene ezicelo ezinkulu zengqalasizinda, sigqamisa izinzuzo zokuzinza eziyilethayo, futhi sethula imikhiqizo enikezwa yi-Geofantex Geosynthetics, umkhiqizi ohamba phambili ozibophezele ekwenzeni izinto ezintsha nokwethembeka kule ndawo eguquguqukayo.

Ama-geosynthetic enziwa ngezinto zamapholiyemitha njengama-polypropylene, i-polyester, i-polyethylene, kanye ne-polyamide, ezicwengwa zibe ama-sheet, ama-grid, amanethi, noma izakhiwo ezihlanganisiwe eziklanyelwe izicelo zobunjiniyela be-geotechnical kanye nezemvelo. Leli gama lihlanganisa umndeni omkhulu wezinto, ngayinye yakhelwe ukwenza imisebenzi eyodwa noma ngaphezulu eyinhloko, okubandakanya ukuhlukanisa, ukuqinisa, ukuhlunga, ukudonsa amanzi, ukubamba, nokuvikela. Phakathi kwezinhlobo ezisetshenziswa kakhulu kukhona ama-geotextile, okuyizindwangu ezivumela ukudlula kwamanzi ezikhethekile ezindimeni zokuhlukanisa nokuhlunga; ama-geogrid, okuyizakhiwo ezinemingcele evulekile ezinikeza ukuqinisa okunamandla ezindaweni zomhlaba; ama-geonet, anesakhiwo esinjengenethi esiklanyelwe ukudonsa okungaphakathi kwezinto eziyisiketshezi neziyigesi; futhiama-geocomposite, okuhlanganisa izinto ezimbili noma ngaphezulu ze-geosynthetic ukuletha ukusebenza okuningi ngesendlalelo esisodwa, esilula ukusifaka. Ngaphezu kwalokho, ama-geomembrane asebenza njengezithiyo ezingangeni manzi ezindaweni zokubamba, kanti ama-geosynthetic clay liners ahlanganisa isendlalelo se-bentonite clay ne-geotextiles ukuze kuthuthukiswe ukusebenza kwe-hydraulic. Ngamunye walezi zinhlobonhlobo ubhekana nezidingo ezithile zobunjiniyela, futhi ukukhethwa komkhiqizo ofanele kuncike ezintweni ezifana nezimo zomhlabathi, imithwalo yokuklama, ama-hydraulic gradients, nokuchayeka kwemvelo. Ukuguquguquka kwe-geosynthetics kuncike ekubeni kwazo namandla okubuyisela izinto zokwakha zendabuko njengezendlalelo zomhlabathi oqoshiwe, izihlungi zesihlabathi, ne-concrete, ngokuvamile ngengxenye encane yezindleko futhi ngokusebenza okungcono kwesikhathi eside. Njengoba izidingo zengqalasizinda ziqhubeka nokwanda emhlabeni wonke, indima ye-geosynthetics ekunikezeni izixazululo eziphumelelayo, ezimelana nezimo, neziyisimeme ayikaze ibe yinhloko kangako.

Ekhiweni lokwakha imigwaqo, ama-geosynthetics asetshenziswa ukuthuthukisa ukusebenza nokuqina kwemigwaqo ngokubhekana nezinselelo ezintathu ezibalulekile: ukuzinza komhlaba ongaphansi, ukuqinisa umbhede oyisisekelo, nokuhlukanisa phakathi kwezinto ezihlukene. Lapho umgwaqo wakhiwa phezu komhlaba ongaphansi obuthakathaka noma obuthakathaka emanzini, ukufakwa kwe-geogrid eqinile noma i-geotextile engalukiwe phakathi komhlaba ongaphansi nombhede oyisisekelo samatshe kusabalalisa imithwalo yethrafikhi ngokulinganayo, kunciphisa ukuguguleka, futhi kuvimbela ukuxubana komhlabathi namatshe okungenzeka konakalise ukuqina komgwaqo.
