3. Ubunjiniyela Bezakhiwo kanye Nengqalasizinda
4. Izicelo Zezimboni Nezikhethekile
Kungani Ama-Sika Sealants Ehola Imakethe
Ukubusa kukaSika kuvela ezinsikeni ezintathu:ukusungula izinto ezintsha kwezobuchwepheshe, ukuqinisekisa ikhwalithi, futhiukusimamaLe nkampani itshala imali eningi ku-R&D, kanye nezikhungo zokuhlola zomhlaba wonke eziqinisekisa ukuthi imikhiqizo ihlangabezana noma idlula i-ISO, i-ASTM, kanye nekhodi yokwakha yendawo iSika Group. Ama-sealant e-Sika nawo aklanyelwe ukujikeleza: amafomula amaningi angasetshenziswa kabusha, ane-VOC ephansi, futhi anikela ekuqinisekisweni kwezakhiwo eziluhlaza ze-LEED kanye ne-BREEAM.
Kwabakhi bezindlu, abakhi bezakhiwo, kanye nabanini bezindlu, iSika inikeza okungaphezu kwemikhiqizo—inikeza ukwesekwa okuphelele: ukubonisana ngobuchwepheshe, ukuqeqeshwa endaweni, kanye nezixazululo ezenziwe ngokwezifiso zamaphrojekthi ayinkimbinkimbi iSika Group. Le ndlela ephelele yenze iSika yaba ngumlingani othembekile wezakhiwo ezidumile emhlabeni wonke, kusukela ezakhiweni eziphakeme kuya emabhulohweni kuya emiphakathini yokuhlala.
Isiphetho
Ama-sealant e-Sika amelela indinganiso yegolide kubuchwepheshe bokuvala, ahlanganisa ukunemba kwaseSwitzerland nokuzivumelanisa nezimo emhlabeni jikelele. Kungakhathaliseki ukuthi ukuvala i-joint yethayela lokugeza, i-facade ye-skyscraper, noma i-joint yokwandisa umgwaqo omkhulu, i-Sika inikeza ukusebenza okuqhubekayo, okuhlala isikhathi eside okuvikela izakhiwo, okuthuthukisa ukusebenza kahle, futhi okusekela imikhuba yokwakha esimeme. Njengoba imboni yokwakha ithuthuka iye engqalasizinda eluhlaza futhi eqinile, izixazululo ezintsha ze-sealant ze-Sika zizoqhubeka nokudlala indima ebalulekile ekwakheni indawo eyakhiwe amashumi eminyaka ezayo.
