Pipe cracking (bursting) is a technology by which old pressure or gravity flow pipes are completely destroyed. In place of them, into a newly formed tunnel, new plastic pipes of the same or larger diameter are pulled in.

Depending on infrastructure intended for renovation, either short joinable pipes or long pipes can be pulled in. The technology is suitable for rehabilitation of water or sewer lines.

The pipe cracking is the optimal solution, when:
  • the surface of the land shall not be damaged (as in a case when a road or railroad goes or a building stands above the utility lines, or when the existing landscaping shall be preserved, etc.);
  • there is a complicated subsurface utility network installed;
  • to-be-renovated line is up to 100 m long (depending on the soil humidity);
  • the soil is heterogenous;
  • diameter of the new pipes is the same or up to 50% larger than of existing ones.

The pipe cracking is well suited for installation of pipes 100-500 mm in diameter. To ensure smoothness of work, the existing pipes shall be scoured out and appropriate diagnostics shall be performed before.

Pipe cracking enables you to:
  • Take care of the renewal of various pipelines. The pneumatic equipment easily cracks ceramic, cast iron, bitumen concrete, metal, ferroconcrete, and other pipes.
  • Accelerate project completion and make the job easier – pipe cracking technology makes possible to install water or sewer lines between two manholes without making the working pits. Job completion time is 50% shorter comparing to the work usually done at the surface. Also, the pneumatic pipe cracking tool is easy to handle and combine with a pipe of required diameter.
  • Ensure comfort – when employing this technology, it is not necessary to disrupt or restrict road or railroad traffic. Due to silent work of the equipment and low work-related traffic, tranquillity of densely inhabited areas is preserved.
  • Decrease pipe installation costs – it is necessary to prepare only a small ground surface area, thus the environment restoration costs are lower. Since the pipe-cracking waste remains on the spot, the amount of excavated soil decreases by 90%.

Due to its simplicity, reliability, applicability and cost-effectiveness, the pipe cracking is one of the most popular pipe replacement methods over the world. Although, these advantages can be achieved only when the certified professional equipment (the winch, reamer, and pneumatic pipe cracking equipment) is used.
