Imakethe yomhlaba wonke yezinto zokugqoka umhlaba (geotextile) ithola ukukhula okungakaze kubonwe ngaphambili, okuqhutshwa ukuhlangana kokukhula ngokushesha kwamadolobha, isidingo esikhulayo sezixazululo zokwakha ezingabizi kakhulu, kanye nokugxila okukhulayo ekuvikelweni kwemvelo. Njengoba amadolobha ekhula futhi ingqalasizinda endala idinga ukulungiswa, isidingo sezinto zokwakha eziphakeme (geosynthetic) asikaze sibe sikhulu kangaka. Izinto zokugqoka umhlaba (geotextiles), okuyizindwangu ezingenawo umoya ezisetshenziswa kanye nomhlabathi ukuhlukanisa, ukuhlunga, ukukhipha amanzi, nokuqinisa, sezibalulekile emaphrojekthini obunjiniyela bomphakathi emhlabeni wonke. Phakathi kwezinkampani ezihamba phambili embonini ezibhekene nalesi sidingo esikhulayo yiGeofantex Geosynthetics, inkampani ezibeke phambili ekukhiqizeni izinto zokugqoka umhlaba ezisezingeni eliphezulu kusukela yasungulwa ngo-2014. Ngokuqonda izitayela zakamuva—kusukela ekuhlanganisweni ngokuhlangana nokuthengwa kwezinye izinkampani kuya ekuphumeleleni kobuchwepheshe obuhlakaniphile—onjiniyela nochwepheshe bokuthenga bangenza izinqumo ezinolwazi eziqinisekisa impumelelo yephrojekthi kanye nenani lesikhathi eside lezinhlangano zabo.

Imboni yezinto zokwakha ezenziwe ngendwangu (geotextile) ibone igagasi elikhulu lokuhlanganiswa nokuthengwa kwezinye izinkampani eminyakeni eyishumi edlule, okushintshe kakhulu indlela izimbangi ezincintisana ngayo kanye nokuhamba kwezinto ezidingekayo emkhiqizweni. Izinkampani ezinkulu ezingamazwe ngamazwe bezilokhu zithenga abakhiqizi abakhethekile ukuze zandise imikhiqizo yazo futhi zithole amathuba ezimakethe ezintsha ezifundeni ezahlukene. Lokhu kuhlanganiswa kuholele ekongeni okukhulu ezindlekweni zokuthola izinto zokusetshenziswa kanye nokukhiqiza, okusize ukuzinzisa amanani entengo kubasebenzisi bokugcina. Nokho, lokhu nakho kudale ubungozi ekuhambeni kwezinto ezidingekayo lapho izinkampani ezithengiwe zihlelwa kabusha noma lapho izindawo zokukhiqiza zihlanganiswa zibe yizindawo ezimbalwa. Kubaphathi bamaphrojekthi nokontraka, lesi simo esishintshayo sisho ukuthi ukusebenzisana nomkhiqizi ozimele onokwethenjelwa njengeGeofantex Geosynthetics kunikeza izinzuzo ezithile. IGeofantex igcina inqubo yokukhiqiza ehlanganisiwe yemikhiqizo ehlanganisaama-geotextile alukiwe ukuya ezinhlobonhlobo ezingenziwanga, ukuqinisekisa ukulawulwa kwekhwalithi okungaguquki kanye nezinhlelo zokulethwa ezithembekile lapho izinhlangano ezinkulu ngezinye izikhathi zihluleka ukufinyelela.

Umthelela walezi zinguquko zemboni ufinyelela ngqo endleleni izindwangu zomhlaba (geotextiles) ezichazwa ngayo futhi zithengwe ngayo emaphrojekthini amakhulu engqalasizinda. Onjiniyela namuhla baya ngokuya bedingeka ukuthi babhekisele ezindinganisweni ezifana ne-AASHTO M288, enikeza imihlahlandlela ecacile yokuhlukaniswa kwezindwangu zomhlaba kanye nezidingo zokusebenza ezintweni zomgwaqo nezokuthutha. Ukuqonda ukuthi izinketho ezahlukene zezinto zokwakha ze-geosynthetic zihambisana kanjani nalezi zindinganiso kubalulekile ekuqinisekiseni ukusebenza kwepavimenti isikhathi eside kanye nokuzinza kwengqimba engaphansi komhlaba (subgrade). I-Geofantex ikhiqiza uhla olugcwele lwemikhiqizo ehlangabezana noma eyeqa lezi zindinganiso eziqinile, okuhlanganisaama-PP woven geotextiles aklanyelwe ngokukhethekile ukuhlukanisa nokuqinisa ekwakhiweni kwemigwaqo. Ngokukhetha abahlinzeki abanokuthobela okufakazelwe kwe-AASHTO M288 namanye amazinga omhlaba, osonkontileka banganciphisa ubungozi futhi bagweme ukulungiswa okubizayo kamuva.

Enye yezinselelo eziphuthumayo ezibhekene nomkhakha we-geosynthetics namuhla ukukhathazeka okukhulayo mayelana nokungcoliswa kwe-PFAS (i-per- ne-polyfluoroalkyl substances) emhlabathini nasemanzini angaphansi komhlaba. Lawa "makhemikhali angapheli," asetshenziswe kabanzi ezinqubweni zezimboni nasemikhiqizweni yabathengi, abeka izingozi ezinkulu zemvelo nezempilo. Ukuphendula, abakhiqizi baye bathuthukisa izinhlelo zokufaka ulayini ezingaphambili ezingavimbeli nje kuphela ukuthuthela kokungcolile kodwa futhi zimelane nokucekelwa phansi kwamakhemikhali ezikhathini ezinde zokusebenza. Ama-geotextiles ekwakhiweni kwemigwaqo nasekusetshenzisweni kwezindawo zokulahla imfucuza manje avame ukufaka ama-composite liners ahlanganisa ama-geotextiles nama-geomembranes nama-geosynthetic clay liners ukuze akhe izithiyo eziqinile zokuqukatha. I-Geofantexi-geosynthetics clay liner (GCL) izixazululo zibonisa le ndlela, zinikeza ukusebenza okuphezulu kwe-hydraulic kanye nezici zokuzivalela ezibalulekile ekuvimbeleni i-PFAS nezinye izinto ezingcolisayo ukuthi zingangeni emvelweni ezungezile.

Intuthuko yezobuchwepheshe ekuvikelweni kwe-PFAS ihambisana nezinto ezintsha zesayensi yezinto ezibonakalayo kanye nezinqubo zokukhiqiza. Izindwangu zesimanje ze-geotextile zakhiwe ezingeni lamangqamuzana ukuze zinikeze ukumelana namakhemikhali okuthuthukisiwe ngenkathi zigcina izici zokungena ezidingekayo ukuze kukhishwe amanzi nokuhlunga okusebenzayo. I-Geofantex itshale imali enkulu ocwaningweni nasekuthuthukisweni ukuze yakhe izinhlelo zokugqoka ezibhekana nezinselele eziqondile zezindawo ezingcolile, okuhlanganisa izindawo zokulahla udoti, izindawo ezingcolile zezimboni, kanye nezikhungo zokuhlanza amanzi angcolile.i-HDPE geomembrane uma isetshenziswa kanye nezingqimba ze-geotextile ezivikelayo, yakha uhlelo oluphelele lwe-barrier oluhlangabezana nemithetho eqinile kakhulu yezemvelo. Konjiniyela abasebenza emisebenzini yokulungisa, lezi zixazululo ezihlanganisiwe zinikeza ukuthula kwengqondo ukuthi uhlelo lokuvalela luzosebenza ngokuthembekile amashumi eminyaka.

Ukusimama sekushintshile kusuka ekuhlukaniseni imakethe kuya esidingweni somkhakha embonini ye-geotextile. Abakhiqizi baya ngokuya besebenzisa izinto ezingavuselelwa ezigaywe kabusha, basebenzisa izinqubo zokukhiqiza ezingenamfucuza, futhi basebenza ngenkuthalo ukunciphisa umkhondo wabo wekhabhoni kulo lonke uchungechunge lokuhlinzeka. Imicu ye-polypropylene ne-polyester egaywe kabusha manje isetshenziswa kakhulu ekukhiqizweni kwama-geotextile angawelwanga, enikeza ukusebenza okufanayo nezinto ezingasetshenziswanga kuyilapho kususwa imfucuza yepulasitiki ezindaweni zokulahla. I-Geofantex yamukela lolu shintsho ngemikhiqizo yayo enobungani bemvelo, ehlanganisa okuqukethwe okugaywe kabusha ngemuva kokusetshenziswa kwabathengi nangemuva kwezimboni ngaphandle kokulahlekelwa amandla okuqina nokuqina okulindelwe amakhasimende. Imikhiqizo efana ne-i-geotextile engenziwanga yensimbi ye-polyester staple fiber (GFS) khombisa ukuthi ukukhiqiza okusimeme kungahambisana kanjani nezidingo zobunjiniyela eziphakeme.

Ukuqhubekela phambili ekusimemeni kuhlanganisa wonke umjikelezo wempilo yemikhiqizo ye-geotextile, kusukela ekukhishweni kwezinto ezingavuthiwe kuya ekulahleni noma ekugayweni kabusha ekupheleni kwempilo. Izinto ezintsha kuma-biodegradable geotextiles ezisetshenziselwa ukulawula ukuguguleka kwesikhashana ziya zithola ukuthandwa, kuyilapho ukuqina kwama-synthetic geotextiles kusho ukuthi ukufakwa okungapheli kungahlala kusebenza iminyaka engu-50 noma ngaphezulu, kunciphisa isidingo sokushintshwa futhi kunciphisa ukusetshenziswa kwezinto ngokuhamba kwesikhathi. I-GEOFANTEX i-geotextile engenazintambo eziqhubekayo ye-polypropylene (GFL) inikeza ibhalansi enhle yokuphila isikhathi eside kanye nomthwalo wemfanelo wemvelo, ikhiqizwa ngaphansi kwezinhlelo zekhwalithi eziqinisekisiwe ze-ISO ezilandelela futhi zinciphise imfucuza. Ezinhlanganweni ezizibophezele ezitifiketini zokwakha eziluhlaza ezifana ne-LEED noma i-Envision, ukukhetha ama-geotextile avela kubakhiqizi abanemikhuba esobala yokusimama sekuyingxenye ebalulekile yokufeza izinjongo zokusimama zephrojekthi.

Esikhathini sezimali ezinzima zengqalasizinda kanye nezindleko ezikhulayo zezinto zokwakha, ingxoxo mayelana namanani entengo ye-geotextile isiba nzima kakhulu kunangaphambili.
