The drilling at the Changuinola I dam in Panamá was finished more than three months ahead of Schedule, thanks to the Wassara water-powered drilling.
The Wassara technology was used for drilling the foundation drainage and grouting holes and was chosen as it has delivered successful results at a number of similar dam projects around the world.
The drilling project was considered a complete success. The borehole and grouting results were as hoped for and the costs of drilling was much lower compared to what alternative core drilling methods would have cost.
