Nei Sika Sealants Vachitungamira Musika
Kutonga kwaSika kunobva pazvikamu zvitatu:hunyanzvi hwekugadzira zvinhu zvitsva, vimbiso yemhando yepamusorouyekuenderera mberiKambani iyi inodyara mari yakawanda muR&D, ine nzvimbo dzekuongorora dzepasi rose dzinoona kuti zvigadzirwa zvinosangana kana kupfuura ISO, ASTM, uye makodhi ekuvaka emunoSika Group. Sika sealants dzakagadzirirwawo kutenderera: akawanda maformula anogona kudzokororwa, ane VOC shoma, uye anobatsira muLEED neBREEAM green building certifications.
Kune varidzi vezvivakwa, vanogadzira mapurani, nevaridzi vedzimba, Sika inopa zvinopfuura zvigadzirwa chete—inopa rutsigiro rwese: kubvunzana kwehunyanzvi, kudzidziswa panzvimbo, uye mhinduro dzakagadzirirwa mapurojekiti akaomarara eSika Group.

Mhedziso
Zvivharo zveSika zvinomiririra mwero wepamusoro muhunyanzvi hwekuvhara, zvichisanganisa kunyatsojeka kweSwitzerland nekuchinjika kwepasi rose. Kungave kuvhara chivharo chemataira emumba yekugezera, facade yedenga refu, kana chivharo chekuwedzera mugwagwa mukuru, Sika inopa mashandiro akasimba, anodzivirira zvivakwa, anowedzera kushanda zvakanaka, uye anotsigira maitiro ekuvaka anogara kwenguva refu. Sezvo indasitiri yekuvaka ichifambira mberi kuenda kune zvivakwa zvakasvibira uye zvinogara kwenguva refu, mhinduro dzeSika dzezvivharo dzicharamba dzichiita basa guru mukuumba nharaunda yakavakwa kwemakumi emakore anotevera.
