Tina River hydropower starts placing roller-compacted concrete for its main dam
The 15 MW Solomon Islands project began its main dam on 26 October, in 67 layers of 300 mm each, and plans to start tunnel boring in December.
For you: Roller-compacted concrete is the method of choice for many new gravity dams because it is placed with earthmoving equipment and cures with less heat build-up. Tina River shows the method's layer-by-layer logic, and how a geological problem at one abutment can pause a dam's growth even while the rest of the work goes on.
