The bursting procedure is used when the function of the old pipe is disturbed, e.g. in the case of offsets, cracks, missing invert or partial collapse, or when repair/renovation is no longer possible. The method is also suitable for pipelines whose hydraulic capacity is to be capacity is to be improved or when a new pipe with a new wear reserve is desired.

The static bursting method is a pipe renewal method that has been established worldwide for decades for the trenchless replacement of defective supply pipes and sewers with a new pipe of the same or larger diameter in the existing route. The sustainable result is a new pipe with a service life of 80 - 100 years. By inserting new pipes with a larger diameter, the pipeline capacity can also be adjusted in the course of the pipe renewal.

Unlike dynamic bursting, in the statistical method the bursting rod is first pushed out of the excavation pit through the old pipeline. Once it has reached the target shaft or the retraction pit, the bursting tool with integrated new pipe is coupled to the pipe string. By simply pulling back the rods statically, tough old pipe material (steel, ductile iron, PE) is cut or brittle material (GG, Stz., concrete, AZ, etc.) is broken and the fragments are displaced radially into the surrounding soil. At the same time, the new pipe made of PE-HD (protective jacket pipes), PP-HM, ductile cast iron, stoneware or GRP is drawn in with the forming of a pipe channel.
