upotusputkijärjestelmä

Upotusputkijärjestelmä, also known as an insertion pipe system or simply a liner, is a rehabilitation method used for repairing damaged underground pipelines without extensive excavation. This technique involves inserting a new, often flexible pipe into the existing, deteriorated pipe. The space between the old and new pipe can then be filled with grout, creating a structurally sound, composite pipe.

The process typically begins with an inspection of the existing pipe to assess its condition and determine the appropriate liner size and material. Access points are established, and the old pipe is cleaned to remove debris and obstructions. The liner, which can be made of various materials like felt, fiberglass, or plastic, is then introduced into the damaged pipe. It might be pulled in, or in some cases, inflated into place. Once positioned, the liner is cured, often using hot water, steam, or UV light, which hardens the material and forms a new, seamless pipe within the old one.

Upotusputkijärjestelmä offers several advantages, including minimal disruption to the surface, reduced environmental impact compared to traditional excavation, and cost-effectiveness for certain types of repairs. It is commonly used for sewer lines, water mains, and industrial pipelines that have suffered from cracks, leaks, or collapse. The durability and longevity of the rehabilitated pipeline depend on the materials used and the quality of the installation.
