Sealing the Melo earth dam with the world’s deepest drilled interlocked pipe pile wall

This documentary tells the story of how the PVO owned Melo hydroelectric power plant in the small Finnish town of Nokia was renovated using the M-Wall interlocked pipe pile wall. Mincon's Spiral Flush air control technology was crucial in the safety and success of the drilling in this kind of sensitive ground. The video is produced together with Mincon, KFS Finland and SSAB.
