Natural hazards such as flooding, rockfalls or landslips have always posed a threat to human settlements and traffic routes. This threat has become more acute due to the quickening pace of spatial development and land use in recent decades. Gruner Böhringer AG and Stucky AG draw on their many years of experience when developing design and technical solutions to avert natural hazards. Case-specific simulations are conducted and hazard maps prepared with the aim of optimizing the scale and cost-effectiveness of these measures. Carefully targeted action plans are then implemented to minimize risks.
