Abstract: The construction programme of Batu Dam was started in July 1984 and completed in the middle of 1987. The dam and its various structures (embankment, outlet works, spillway etc.) are founded on the decomposed to fresh Hawthornden schist of Silurian age with the foliation dipping steeply downstream.
Rock bolt, concrete buttress and removal of overhangs are measures taken to stabilise the unstable rock slopes.
Various types of instruments (e.g. vibrating-wire piezometer) are installed at Batu Dam to monitor the performance of the dam embankment, foundation, abutments and structures during the construction and after the completion of the dam.
The grouting works consist of blanket and curtain grouting ranging in depth from 6.5 m to 40 m. The original design required a one row curtain grouting for the right abutment and a three row curtain grouting for the river valley, left abutment and spillway area. The conditions encountered necessitated minor changes to the whole layout.
