SBM LINEMIX
® produces dam wall concrete under most extreme conditions.
A new arch dam will be built in front of the monumental Spitallamm dam on the Grimsel that needs renovation. SBM Mineral Processing installed two plants type LINEMIX
® 3500 CM 800-6 H plus a recycling plant for residual concrete at this challenging large-scale construction site located at 1,900 m above sea level. Just like the certified concrete mixtures, these plants fulfil all the sophisticated requirements of this centennial project in Switzerland.
Around 1930 the Spitallamm dam – one of the first and biggest arch-gravity dams, a real pioneering work – was built in the Swiss region Bernese Oberland. The need for action now arose because of a crack that has been running through the wall interior for some time. Instead of demolishing or renovating the massive dam, it was decided to build a new double curvature arch dam immediately in front of the existing dam. Costs: CHF 125 million. A big advantage of
