Cha, udaka olomile alufani nosimende, nakuba usimende ungenye yezithako eziyinhloko ekuxubeni kodaka olomile. Usimende uyisibopho esisetshenziselwa ukubamba ndawonye ezinye izinto, njengesihlabathi nama-aggregates, ukuze kwakhiwe ukhonkolo. Ngakolunye uhlangothi, udaka olomile luyingxube esele ixutshwe usimende, isihlabathi, nezinye izithasiselo ezisetshenziswa ezinhlobonhlobo zokwakha, njengokwakha amatshe, ukubeka phansi, ukupulasitela, ukugandaywa kwemigwaqo nokuvimbela amanzi.

Umehluko phakathi kukasimende nodaka olomile usekubunjweni kwakho nasekusetshenzisweni okuhlosiwe. Usimende ngokuyinhloko usetshenziswa njenge-ejenti ebophayo ekukhiqizeni ukhonkolo, kuyilapho udaka olomile luyingxube exutshwe ngaphambili kasimende, isihlabathi, nezinye izithasiselo eziklanyelwe ukuxutshwa namanzi esizeni ngaphambi kokusetshenziswa. Ingxube yodaka olomile ingase futhi iqukathe izithasiselo ezengeziwe, njenge-lime, i-polymer, noma i-fiber, kuye ngokusetshenziswa okuhlosiwe.

Kafushane, nakuba usimende ungenye yezithako ezibalulekile ekuxubeni kodaka olomile, udaka olomile luyingxube exutshwe ngaphambili yesimende, isihlabathi, nezinye izithasiselo ezisetshenziswa emisebenzini eyahlukahlukene yokwakha.
