ABOUT

The Cotter Dam is a concrete gravity and rockfill embankment dam across the Cotter River, located in the Australian Capital Territory, Australia.

IMPLEMENTATION

CPR Services undertook polyurethane injection with customised injection equipment. This enables CPR to seal the major diversion plug and permanent plug in a single session of works for each item.
Works were completed over two, four days sessions of work. This was done in conjunction with Professional Diving Services as this operation was deep diving (up to 50m), at altitude and cold.
