Selected Technique:<\/span> Treatment Area: Project Depth:<\/span> Capital Regional District (CRD) needed to remediate the right abutment of Butchart Dam No.5 in the Goldstream Watershed of the Regional Water Supply System located near Victoria, BC.<\/p>\n Menard performed Permeation\/Foundation Grouting to create a grout curtain along the alignment of the dam crest, thus a barrier for the flow of water downstream. The grout curtain was constructed in a grid pattern extending 20m below the dam crust.<\/p>\n Permeation Grouting is a widely accepted methodology to stabilize a structure’s foundation through grout injection and to fill the voids. Grout is pumped through a specialized Grout pipe\/Tube with perforations and ballons to ensure a controlled injection of grout into the fractured bedrock. Boreholes were drilled from the dam crest until the treatment depth to insert the tube. This technique allows the flow of a sufficient volume of grout at a very low pressure to avoid any appreciable movement of the bedrock surrounding the tube. The grout is pumped in multiple phases by both Gravitational fillings and a specialized setup until all the voids are filled. The main advantage of this technique is the formation of a strong bond that is both waterproof and permanent. The whole execution is clean, non-intrusive, and non-destructive.<\/p>\n The results from this technique were observed almost immediately by the drop in the water level leaking downstream.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div><\/div>
