Haufinyane tjena, li-mixer tse peli tsa 200-liter high shear grout tse hlophisitsoeng ke k'hamphani ea rona bakeng sa moreki oa Danish li qetile mekhoa eohle ea ho amohela 'me li se li tla romelloa Denmark. Tsoelo-pele e ntle ea odara ena e bonts'a botsebi ba Henan Wode Heavy Industry Co., Ltd. le bokhoni ba ts'ebeletso ea lefats'e lefapheng la tlhahiso ea lisebelisoa tsa boenjiniere ba grouting, e hapang kananelo ho tsoa ho bareki ba machaba ba litsebi ba boenjiniere.
Ka Pulungoana 2025, k'hamphani ea rona e ile ea fumana patlisiso ea theko ho tsoa ho moreki oa Danish ea neng a kopile lithara tse 150-200 ka kotloloho.
