Ubufakazi obuvela emaphrojekthini angempela bucacile: izinhlelo ze-geosynthetic eziklanywe kahle futhi zafakwa kahle ziletha ukuthuthuka okukalekayo ekusebenzeni kwengqalasizinda, zinciphisa izindleko zephrojekthi, zifinyeza izikhathi zokwakha, futhi zinomthelela ezinhlosweni zokusimama kwemvelo ezibaluleke kakhulu ezinhlanganweni ezixhasa ngemali nasemphakathini. Komakhi bengqalasizinda, onjiniyela, nezikhulu zikahulumeni ezinikezwe umsebenzi wokuvikela imiphakathi yazo, isinqumo sokufaka ama-geosynthetics ezinhlelweni zokulungiselela izinhlekelele akulona nje ukukhetha kwezobuchwepheshe kodwa kuyisidingo esingamasu esingasindisa izimpilo, sivikele impahla, futhi silondoloze imvelo yemvelo ezizukulwaneni ezizayo. I-Geofantex Geosynthetics imi ilungele ukuba uzakwethu kulo msebenzi obalulekile, inikeza uhla olugcwele lwemikhiqizo yekhwalithi ephezulu, ubuchwepheshe obujulile, nomlando oqinisekisiwe wempumelelo emaphrojekthini emhlabeni wonke, kusukela ekuvikelweni kogu olumelana neziphepho kuya ezinhlelweni zokulawula ukuguguleka komhlaba ngemva kwemililo yasendle. Isikhathi sokuthatha isinyathelo manje, ngoba inhlekelele elandelayo akukhona ukuthi ingenzeka yini kodwa ukuthi izokwenzeka nini, futhi utshalomali olwenziwa namuhla engqalasizindeni eqinile luzoholela ezinzuzweni emashumini eminyaka ezayo ngendlela yemiphakathi ephephile, eqinile, futhi esimeme engamelana namandla emvelo ngokuzethemba.

Geofantex Geosynthetics imema abahleli bengqalasizinda, onjiniyela bomphakathi, kanye nochwepheshe bezemvelo ukuthi bahlole uhla olugcwele lwemikhiqizo nezixazululo ezitholakala kuwebhusayithi yabo ebanzi, ehlanganisa imininingwane yemikhiqizo, izifundo zamacala, izindatshana zobuchwepheshe, kanye nokufinyelela oqondile eqenjini lochwepheshe abangahlinzeka ngokuqondisa okukhethekile kunoma yimuphi umsebenzi. Noma ngabe isidingo siwukuqiniswa kwenhlabathi ngama-geogrid anamandla aphezulu, ukuphathwa kokukhipha amanzi ngezinhlelo ezithuthukisiwe ze-geonet ne-geocomposite, ukulawulwa kokuguguleka komhlabathi ngama-geocell blankets aqinile, noma ukuvalwa ngama-geomembrane angangeni manzi kanye nama-geosynthetic clay liners, iGeofantex inemikhiqizo, ulwazi, nokuzibophezela kwekhwalithi okufunwa ukulungela izinhlekelele. Ngokukhetha iGeofantex, izinhlangano azithengi nje izinto zokwakha kodwa zitshala ekubambisaneni okuzozisiza ukuthi zibhekane nobunkimbinkimbi bokuqina kwengqalasizinda yanamuhla ngokuzethemba nobuchwepheshe. Izinselele ezibangelwa ukushintsha kwesimo sezulu kanye nokwanda kwemvamisa yezinhlekelele zinkulu, kodwa ngamathuluzi afanele, ulwazi, nabalingani, imiphakathi ingakha ikusasa lapho ilungiselele okubi kakhulu ngenkathi iqhubeka nokuchuma ngezikhathi ezinhle. Kulabo abazimisele ukuthatha isinyathelo esilandelayo, iGeofantex ingatholakala ngekhasi lokuxhumana kuwebhusayithi yabo, lapho ithimba elizinikele litholakala khona ukuthi lixoxe ngezidingo zomsebenzi, linikeze izilinganiso zezindleko, futhi linikeze imininingwane yobuchwepheshe egcwalisa izinhloso ezimangalisayo zokuqina zibe yiqiniso elifezekisekayo.

I-geosynthetic iyinto eyisicaba, eyenziwe nge-polymeric material eklanyelwe ukusetshenziswa lapho ihlangana nomhlabathi, idwala, noma ezinye izinto ze-geotechnical ukuze yenze imisebenzi efana nokuqinisa, ukwehlukanisa, ukuhlunga, ukukhipha amanzi, ukuqukatha, nokulawula ukuguguleka komhlabathi. Ekulungiseleleni izinhlekelele, ama-geosynthetics asetshenziswa ukuqinisa imidigo (levees) ngokumelene namagagasi ezivunguvungu zasezilwandle, ukuphatha ukugeleza kwamanzi ngesikhathi sezikhukhula, ukuqinisa imithambeka ngemva kwemililo yasendle, nokuqukatha izinto eziyingozi ngesikhathi sezimo zezulu ezinzima, kunikeza ukuvikelwa okuguquguqukayo nokonga izindleko ezingqalasizinda ezibalulekile.

Izinhlobo eziyinhloko zama-geosynthetics zihlanganisa ama-geotextiles (alukiwe nangalukiwe), ama-geomembranes (HDPE, LLDPE), ama-geogrids (uniaxial, biaxial, triaxial), ama-geonets, ama-geocells, ama-geosynthetic clay liners (GCLs), nama-geocomposites, ahlanganisa izinhlobo ezimbili noma ngaphezulu zama-geosynthetics zibe umkhiqizo owodwa. Uhlobo ngalunye lusebenza ngemisebenzi ethile, njengokuqiniswa kwenhlabathi ngama-geogrids, ukuqukethwe koketshezi ngama-geomembranes, ukukhipha amanzi ngama-geonets, nokulawula ukuguguleka komhlabathi ngama-geocells, okuvumela onjiniyela ukuthi bakhethe impahla efanele kunoma yisiphi isimo senhlekelele.

I-geogrid iqinisa imigwaqo yamanzi (levee embankments) ngokunikeza ukuqiniswa kokudonsa (tensile reinforcement) okusabalalisa amandla akhiqizwa ukugcwala kolwandle (storm surge) nokunyakaza kwamagagasi endaweni ebanzi, kuvimbele inhlabathi ukuthi ingasheleli noma ingaqhekeki ngaphansi kwengcindezi enkulu yamanzi. I-geogrid ihlangana nenhlabathi ezungezile, ikhulise amandla ayo okushelela (shear strength) futhi ivumele umgwaqo wamanzi ukuthi ugcine ubuqotho bawo bokwakheka noma ugcwele amanzi ngenxa yemvula ende, okunciphisa kakhulu ubungozi bokuphuka okuyinhlekelele ngezikhathi zeziphepho ezinamandla kakhulu.

I-geocomposite ihlanganisa umgogodla wokukhipha amanzi, njenge-geonet, kanye nongqimba olulodwa noma ngaphezulu lwe-geotextile yokuhlunga ukuze inikeze kokubili ukuhlunga nokukhipha amanzi emkhiqizweni owodwa, osetshenziswa emiseleni yokulawula izikhukhula, emigwaqweni engaphansi kwamadamu, nasezinhlelweni zokukhipha amanzi emithambekeni. Ungqimba lwe-geotextile luvimbela izinhlayiya zomhlabathi ukuba zingene emgogodleni wokukhipha amanzi kuyilapho luvumela amanzi ukuba adlule kalula, futhi umgogodla we-geonet udlulisa amanzi abanjiwe eceleni uye ezindaweni zokuqoqa, kunciphisa ingcindezi ye-hydrostatic futhi kuvimbele ukulimala kwesakhiwo ngezikhathi zezikhukhula.

I-geosynthetic clay liner yakhiwe ngongqimba lukabumba lwe-bentonite olufakwe phakathi kwezingqimba ezimbili ze-geotextile, okunikeza umgoqo wamanzi osebenza kahle kakhulu ozivala ngokwawo uma usumanzi, okubalulekile ekuqukethweni kwezinto eziyingozi ngesikhathi sezikhukhula. Lapho amanzi ezikhukhula egubuzela indawo yokulahla imfucuza noma indawo yezimboni, i-GCL igcina ukuqina kwayo futhi ivimbele ukuhamba kwezinto ezingcolisayo ukuya emvelweni, ngamandla ayo ahlukile okuzilapha emabangeni amancane njengoba i-bentonite ivuvukala, inikeza ukuvikelwa okwengeziwe ekukhishweni kokungcola.

Yebo, ama-geosynthetics afana nama-geocell, izingubo ezigoqwayo zokulawula ukuguguleka komhlabathi, kanye namamata okuqinisa utshani asebenza kahle kakhulu ekuqiniseni izindawo ezishile ngenxa yomlilo wasendle, lapho ukulahleka kwezitshalo kushiya imithambeka isengozini enkulu yokuguguleka komhlabathi nokugeleza kwemfucumfucu ngesikhathi semvula. Le mikhiqizo inikeza ukuvikelwa kwangaphandle ngokushesha, ibamba inhlabathi, futhi idale indawo ezinzile yokumila kwembewu nokukhula kwezimpande, okuvumela izitshalo ukuthi zikhule kabusha ngokushesha futhi kunciphise ubungozi bezikhukhula eziyinhlekelele emiphakathini esemazingeni aphansi ezindaweni ezishile.

Izixazululo ze-geosynthetic ngokuvamile zinciphisa izindleko zizonke zephrojekthi ngamaphesenti angu-30 kuya kwangu-50 uma kuqhathaniswa nezindlela zendabuko ezifana nezindonga zokugcina ukhonkolo, izingqimba zensimbi, noma umsebenzi omkhulu womhlaba, ikakhulukazi ngezindleko eziphansi zezinto zokwakha, ukunciphisa izidingo zokumba, izikhathi zokufaka ezisheshayo, nokusetshenziswa kancane kwemishini esindayo. Ngaphezu kwalokho, ubuncane besisindo se-geosynthetics bunciphisa izindleko zokuthutha, ikakhulukazi ezindaweni ezikude noma ezithintekile yizinhlekelele, okwenza kube ukukhetha okonga kakhulu kwezomnotho kumaphrojekthi engqalasizinda anesabelomali esilinganiselwe.

Ama-geosynthetics asezingeni eliphezulu akhiqizwa ngama-UV stabilizer, ama-antioxidant, kanye nokwakheka kwamapholima okwenziwe ngobunjiniyela aklanyelwe ukusebenza kahle isikhathi esingangeminyaka engu-50 noma ngaphezulu, ngisho nalapho evezwe ezimweni ezinzima zemvelo ezinjengemisebe ye-ultraviolet, ukuchayeka emakhemikhali, nokucekelwa phansi kwezinto eziphilayo. I-Geofantex Geosynthetics yenza wonke imikhiqizo yayo ihlolwe ngokuqinisekisa ikhwalithi ngokuqinile ukuze iqinisekise ukuqina kwesikhathi eside, futhi ukufakwa ngendlela efanele nokuvikelwa kungandisa ngisho nangaphezulu impilo yokusebenza, okwenza lezi zinto zibe ingxenye ehlala njalo yengqalasizinda eqinile.

I-GEOFANTEX Geosynthetics ihlinzeka ngokusekelwa kwezobuchwepheshe okuphelele okuhlanganisa ukuholwa kokukhethwa kwezinto ezikhethekile zephrojekthi, izincomo zepharamitha yokuklama, imibhalo yenqubo yokufakwa, kanye nokumelwa kwezobuchwepheshe endaweni ukuze kuqinisekiswe ukuphathwa nokubekwa kwezinto ngendlela efanele. Ithimba lezobuchwepheshe lenkampani liletha ulwazi lweminyaka eminingi kwezobunjiniyela bomhlaba kanye nokunciphisa izinhlekelele, lisiza amakhasimende ukuthi athuthukise imiklamo yawo ngokusebenza, izindleko, nokusimama, futhi liqinisekisa ukuthi yonke iphrojekthi ihlomula ezixazululweni ze-geosynthetic ezithuthuke kakhulu ezitholakalayo.
