GRUNDOCRACK - Dynamic Pipe Bursting

 

Leaking gas lines due to dried out joints, thick encrustation in water lines, minimising the flow quantity and corrosion in steel pipes, all of these are reasons for the utilities suppliers to replace their over-aged cast iron lines by new HDPE pipes.

The utility companies also have to be on the alert, where sewerage pipes, damaged by corrosion, collapse, misalignment or tree root infestation may lead to sewer leakage or ground water infiltration, thus presenting an environmental risk. The question is: repair, rehabilitation or renewal?

 

 

       

 

Repair
Pipe damage can be repaired by inserting partial in-liners, milling open and spackling or applying other repair methods. This only makes sense if a durable repair can be achieved.

Rehabilitation
Hose in-liner (CIPP) systems cannot meet the demands where static loads, mechanical resistance, durability and hose migration resistance are concerned, especially if an annulus is produced but not filled up and costs can soar with this method.

Renewal
Renewal of the pipe is often the last resort.


Pipe renewal can no longer be avoided, if 

 

  1. pipe repair / rehabilitation is insufficient or too short-lived to be technically or economically viable  
  2. a long service life where an extended pipe performance guarantee is required, or
  3. the position of the pipes are affected
 

 

 

 The pipe bursting method means trenchless pipe renewal – with no disruption to the ground surface. Pipe bursting is an uncompromising perfect pipe replacement technique - no repair, no rehabilitation! We distinguish between dynamic and static pipe bursting methods. Both processes are suited for the pressure pipes and sewerage pipes.

Pipe bursting is definitely state of the art technology. It is defined in the German papers ATV-A 125, GW 304 -Pipe jacking- and GW 323 i.E.
