Raw material quality and safety.
Additionally, TKDZ’s scope of performance includes the supply of so-called rock filling. This refers to the filling of cavities left over from mining activities using appropriate materials, so-called filling or backfilling materials. Filling serves to secure the ridges and to stabilise the mining pillars of endangered mining chambers. As rock filling, TKDZ uses residual materials from the mining and treatment of mined dolomite rock and adds suitable and authorised materials not sourced from mining activities.
