The northern wall of the dam was only 320 m from the nearest houses in Merriespruit. [2] In the early years the slurry had a low relative density that led to difficult construction conditions with seepage and sloughing on the northern wall. A drained tailings buttress was constructed against the face of the northern wall.
A slurry wall is a civil engineering technique used to build reinforced concrete walls in areas of soft earth close to open water, or with a high groundwater table. [1] This technique is typically used to build diaphragm (water-blocking) walls surrounding tunnels and open cuts, and to lay foundations .
Bentonite slurry walls (also known as diaphragm walls [43]) are used in construction, where the slurry wall is a trench filled with a thick colloidal mixture of bentonite and water. [44] A trench that would collapse due to the hydraulic pressure in the surrounding soil does not collapse as the slurry balances the hydraulic pressure.
