Pipebursting and Trenchless Renewal
Hydraulic pipe cracking machines have been known for over 20 years, and are now used to replace old water, sewerage and gas pipes in the ground while installing new pipes of equal or larger diameter. When driving through the old pipe path the old pipe made of stoneware, concrete, steel, PE, grey cast and even cast iron, is cut open with the relevant roller blade technique, or in the case of brittle material, destroyed and pushed into the adjacent soil.
