Abstract
Over the last few decades grouting technology has grown into one of the disciplines in geotechnical engineering comprising mainly of foundation treatment of dams and other structures by strengthening or by making them impermeable and has become one of the main tool to rehabilitate the dams structurally. The present case study deals with structural rehabilitation of Tillar earthen dam which was constructed in 1987 but distress signals had started from the first impounding. Highly permeable strata having permeability to the tune of 0.36 x 10-1 cm/sec was existing between the bottom of Cut off Trench (COT) and foundation rock. From this zone water was permeating and causing danger to the stability of the dam. Grout curtain in the permeable zone, below COT bed and upto foundation rock by using the special technique namely Tube-a-Manchatte Grouting was used to reduce the permeability from 10-1 cm/sec to 10-5 cm/sec and also to provide grout curtain in foundation rock upto 7 m depth.
