A major pipe bursting task in Geneva

It was a mammoth task for the PIASIO company, a daughter company of COLAS SWITZERLAND had ahead of them in Geneva Meyrin. Applying a GRUNDOBURST, Type 2500 G (250 t pulling force), an over-aged and under-dimensioned 500 mm drinking water transport pipe made of grey cast iron was to be replaced by a 730 mm concrete pipe with a steel core, type BONNA.
