Igama le-mineralogical le-bentonite yi-montmorillonite, futhi i-bentonite yemvelo ihlukaniswe ikakhulukazi 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 ye-bentonite engangeni manzi ngamandla athile okudonsa kanye nokubhoboza.
