Ukugrouta kwekhethini kuyindlela ebalulekile yezezimali ezibhalwe yizinsiza zokwakha ezisetshenziselwa ukunciphisa ukufudumala komhlabathi nezinto zokwakha, kudalwa isithiyo esiqhubekayo sokuvimbela ukugeleza kwamanzi nokuhamba kwamanzi phansi. Le msebenzi ibandakanya ukucindezela izinto ezikhethekile zokugrouta emhlabathini ngendlela ehlelekile, ngokuvamile edlulela emgqeni noma endaweni, ukuze kuthuthukiswe izimo zomhlaba emisebenzini yokwakha okukhaleni okujulile, amabhande, ama-emabankment, nezinye izakhiwo ze-hydraulic. Le nqubo iyingxenye ebalulekile yokuzinzisa umhlaba nokuphathwa kwamanzi ezindaweni lapho ukufudumala kwemvelo kokwakha kuholela ezindleleni ezinamathuba emigudwini, ukusimama kwezenzakalo, noma ukufaneleka komsebenzi. Ukugrouta kwekhethini kubalulekile kakhulu ekwakheni izisekelo lapho kulawulwa ukugeleza kwamanzi phansi ngaphansi kwamakhanda ezikhala, ama-caissons, noma izisekelo ze-raft kuvinjelwe ukukhuphuka komfutho, kunciphisa ukwehla, futhi kuqinisekise ubude besikhathi be-system yokwakha okukhaleni okujulile. Ukuqhutshwa kwemisebenzi yokugrouta kwekhethini kudinga ulwazi olunembile ngogesi wesigrafu, izimo ze-hydrogeological, kanye nezindlela zokusebenza zomhlabathi. Ukusebenza kokugrouta ngokuvamile kulandela ama-grid wokubhola aqinile, lapho izikhala zokucindezela zingena okuthile okuphenywe emiphumeleni yokuhlola umhlabathi, ukuhlola ukufudumala, nezincazelo zokwakha. Izindlela ezivamile zokucindezela zifaka phakathi ukugrouta kwenqubo, lapho izingxenye ezilandelanayo zamabhoreholes zithola izicelo zokugrouta ngokuqhubekayo kumanani ahlukene nezinhlaka, kanye nokugrouta komalungu, okungahlanganisa ukushayela amanqamu amaningi ukuze kuhlakazeke izikhala zendlela. Ukukhetha izinto zokugrouta kusekelwe ezimweni zomhlaba, ekunciphiseni ukufudumala okuhlosiwe, nasezinhlinzweni zemvelo, okuhlanganisa ne-light slurries ne-clay-cement mix ukuya kumagrothi ema-chemical kanye nemishanguzo ye-polyurethane. Abaklami kumele baphathe ngokuqinile umfutho wokucindezela ukuze bagweme ukwehla komhlaba okweqile, ukwethuka kwezigaba ezithambile, noma ukusanda kokugrouta okungaqondakali okungabeka ingcuphe ezakhiweni eziseduze. Ukukhethwa kwemishini yokusebenza kokugrouta kwekhethini kubalulekile empumelelweni nasekuhlinzekeni kahle kwemisebenzi. Amadayisi aphezulu wokugrouta, okubandakanya amadayisi ezikhwama nezinsiza zokuhlangana, ahlinzeka ngamaphesenti ahlanzekile namandla adingekayo ukuze kuhlangatshezwe imfuyo esezingeni eliphakeme emadwaleni aqinile noma emhlabathini ophakeme. Izinsiza zokubhola kumele zisebenze ukuze ziqhube kahle emisebenzini, zibuyele endaweni yokuhlola, ngezinsiza zokubhola ezivamile noma izinsiza zokucindezela ngokuya ngempilo yomhlaba. Izimboni zokuxuba ziqinisekisa ukufana kwezinto, kuyilapho izilinganiso zokuhamba, izilinganiso zengcindezi, kanye nezinhlelo zokuhlola izinga lokugrouta zigcina ukuhambisana nezincazelo zomsebenzi futhi zivumele ukufakwa kwezimo zokucindezela ngesikhathi sangempela. Izinsiza ezixhasayo zifaka phakathi ama-compressor wezinsiza zokubhola zomoya nezimpahla zokuhlinzeka ezindaweni zamabhorehole. Ukugrouta kwekhethini kuthola ukusetshenziswa okuningi ezindaweni ezihlukahlukene zokwakha ngaphakathi kwesigaba sezisekelo ezijulile. Ekwakheni amabhande nasekuvikeleni, izikhungo zokugrouta zinciphisa ukugeleza ngaphansi kwezisekelo zamasakhiwo, ivikela ekuhlulekeni kokuphuma nokungazinzile kwezinto. Imisebenzi yokwakha engaphansi, okuhlanganisa nezinsiza ze-metro nezephula, zisebenzisa ukugrouta kwekhethini ukuze kulawulwe ukuhamba kwamanzi phansi futhi kuzinyuse izindawo ezithambile ngaphambi kokumba. Izakhiwo ezikwi-metro, izisekelo zomphakeli, nezinhlelo zomgwaqo zisebenzisa ukunciphisa ukufudumala okungqongqo ezindaweni ezibalulekile zokwakha. Ukuhlinzeka emhlabathini ngaphansi kwezinto ezikhona kungase kuhlanganise ukugrouta kwekhethini ukuze kubhekelele izinkinga zokwehla noma zokuphuma kwamanzi, kukhombisa ubuchwepheshe bokuphumelela kokwakha okusha nasekubhujiseni. Ukuphumelela kudinga ucwaningo olunembile lwesayithi, ukukhethwa kwezindlela ezifanele, ukusebenza kwemishini okuhle, kanye nokuhlola ikhwalithi esebenzayo phakathi nenqubo yokucindezela.
