Geobrugg catches 20-tonne record rock

The record was set together with the Swiss Federal Institute for Forest, Snow and Landscape Research at a test facility in Walenstadt, Switzerland. During a trial run for approval testing, the newly-developed flexible rockfall barrier stopped a 20-tonne concrete block free-falling from 43m at 103km/h.

The impact energy ? which reached 8000kJ ? exceeded the previous performance limit for flexible rockfall barriers by 60 per cent.

Four hundred and fifty experts from around the world looked on as researchers dropped the boulder, who collated detailed measurements for certification, which is due to take place this month.

The Swiss Federal Institute for Forest, Snow and Landscape Research found that the Geobrugg AG flexible rockfall barriers, made from high-tensile steel, are just as effective as rigid constructions, while they?re lighter, cheaper and easier to install.

The company has been developing avalanche protection barriers from wire ropes since 1951. The company develops individual netting for specific situations.
