Igama le-mineralogical le-bentonite yi-montmorillonite, futhi i-bentonite yemvelo ihlukaniswe ngokuyinhloko ibe yi-sodium ne-calcium ngokusekelwe ekwakhiweni kwamakhemikhali.I-Bentonite inendawo yokuvuvukala ngamanzi.Ngokuvamile, lapho i-calcium bentonite ikhula, ukwanda kwayo cishe izikhathi ezi-3 kuphela umthamo wayo.Lapho i-sodium bentonite ikhula, cishe iphinda izikhathi ezingu-15 umthamo wayo futhi ingakwazi ukumunca izikhathi ezingu-6 isisindo sayo.Amanzi, i-high density colloid eyakhiwe yi-bentonite enwetshiwe enjalo inempahla yokuxosha amanzi.Ukusebenzisa lesi sakhiwo, i-sodium bentonite isetshenziswa njengento engenamanzi.Ukuze kube lula ukwakhiwa nokuthutha, i-bentonite ikhiyiwe phakathi kwezingqimba ezimbili zezinto ze-geosynthetic ukuvikela nokuqinisa ingubo ye-GCL bentonite engangeni manzi nge-tensile jikelele kanye namandla okubhoboza.
