Calibre Pipe Bursting
Partially damaged pipe sections are expanded statically with GRUNDOBURST, whilst a new pipe is pulled in at the same time, an annulus is generated which is usually filled and grouted.Application
: Pressure pipes and gravity gradient lines with free cross sections caused by collapse in the old pipe (drill clear beforehand). A slight cross-section reduction is possible.Types of damage
:Local deformation, cracks, displacement, burst pipes.
