Unyango olungalunganga lwesiseko segqongqo, ukugawula imithi neengcambu, kunye nonyango lomhlaba olungaphelelanga.Ukuhlanganiswa kwendlela kunye nomnqamlezo womhlaba ongaphezulu kwe-1: 5 akuzange kumbiwe kumanqanaba ngokweemfuno zekhowudi ngaphambi kokugcwaliswa; ukugcwaliswa kunye nesiseko somhlaba khange kuhlanganiswe ngokufanelekileyo. <br>Ukuzaliswa kwe-embankment kulawulwa ngendlela engafanelekanga, kwaye izinto ezizaliswayo ezinokuzinza okungakhethiyo zikhethiwe.Xa ingqokelela izaliswe ngumgangatho owahlukileyo womhlaba, indlela yokuzaliswa ayilunganga ngenxa yomgangatho owahlukileyo womhlaba. <br>Amalungu e-sub-filled and semi-excavised subgrade aphethwe ngendlela engafanelekanga, kwaye isiseko somhlaba khange simbe kumanqanaba njengoko kufunwa yimigaqo, sibangela iintanda kunye nokuzinza kwindibano phakathi kwesiseko somhlaba kunye nokuzaliswa. <br>Umxholo wamanzi wokugcwalisa, ukutyeba kwepheyiji evulekileyo, kunye nokukhetha okungafanelekanga kwezixhobo zokuxinana kwenza ukungqinelana okungaphantsi kungonelisi kwaye ukugoba kokuxinana akukho endaweni. <br>Izixhobo zokuhambisa amanzi azigqibelelanga kwaye ukuhamba kwamanzi akululanga.
