A grout curtain was embedded 1-3 m into the bedrocks (shales) to provide stability of the fill and natural alluvial soils in the foundation of the Maina hydro dam. Experiments showed high permeability of the alluvial soils, so a combined method of grouting consisting of packerless, packer, and with a moving pipe made it possible to reduce the cost of the curtain by 30% versus the contract design in which only the packer method of grouting was specified. Bentonite-cement and bentonite slurries containing bentonite clay powder and Portland cement M400 were used for the grouting operations. The results of control tests showed a high density of the grout curtain with permeability coefficient within limits up to 0.5-1.0 m/day.
