Izitini zebhulokhi ziwuhlobo olusha lwempahla yodonga, olubukeka kakhulu njengehexahedron elingunxande kanye namabhulokhi ahlukahlukene angajwayelekile. Izitini zokuvimba ziyizinto ezenziwe ngokhonkolo, imfucuza yezimboni (i-slag, impushana yamalahle, njll.), noma imfucuza yokwakha. Banezici zosayizi ojwayelekile, ukubukeka okuphelele, nokwakhiwa okulungile, futhi bahlangabezana nezidingo zokulungiswa kodonga ekuthuthukisweni kwezimboni zokwakha. Kusetshenziswa amabhlogo namabhuloki amakhulu. Lapho ukhetha imishini yomshini wokwakha othomathikhi we-block, khetha imishini enezinga eliphakeme lokuzenzakalelayo, okuthuthukisa kakhulu ukusebenza kahle kokukhiqiza.

Isibonelo, izitini ze-wall block, izitini zokuzibamba, izitini eziqinile, njll. ezisetshenziswa ekwakhiweni kwebhilidi, i-slope masonry yamanzi, izitini ezinemibala (ezivunyelekayo) zomgwaqo we-square landscaping kamasipala, amabhlogo okuhlobisa, ama-curbstones, ama-curbstones, kanye nemishini yama-block ezenzakalelayo yokutshala nokufaka amahhashi esiliva angadla imfucuza enkulu yokwakha. Ukukhiqizwa kwezitini zebhulokhi njengezinto zokwakha eziluhlaza kunochungechunge lwezinzuzo ezinjengokunciphisa ukungcoliswa kwemvelo, ukonga izindleko zokukhiqiza, ukukhulisa izindleko zezindlu, ukwehlisa ukumelana nokuzamazama komhlaba kwesakhiwo, njll. Ukukhanya kwaso okungasindi, ukufakwa kwe-thermal, ukufakwa komsindo, ukwahlukanisa, okungenayo i-formaldehyde, okungenayo i-benzene, ukungangcoli, ukungangeni kwamanzi, ukuvikela umswakama, nezinye izici zikhuthazwa ngamandla ezweni.
