After drilling the hole, it is tested for alignment and for water
tightness. An alignment survey of the hole is completed with an
electronic inclinometer, and the hole is surveyed with a video camera.
The hole is then water tested at three different levels using a
pneumatic packer: the bond zone, the foundation interface and the dam
interior. Due to the extremely fractured rock under the dam, all the
inclined holes failed the initial water tightness test.
