Umbala welitye elihlanganisiweyo lenziwe nge-polymer resin, imathiriyeli ekrwada ye-inorganic, izongezo zekhemikhali kunye nezinye izinto eziluhlaza ngeenkqubo ezikhethekileyo.Isetyenziselwa ikakhulu kwipeyinti yelitye le-granite elilinganisayo elinombala ngaphakathi kunye neendonga zangaphandle zezakhiwo ezikumgangatho ophezulu ukubuyisela i-granite eyomileyo yokuxhoma kwiindonga zangaphandle zezakhiwo eziphezulu.
