The 1st Relining Solution for District Heating Pipes
Use existing manholes or small trenches to enter and exit pipes, and have it replaced in days instead of months. There is no need for new routes or excavating long sections. There is no need for cumbersome and lengthy processes to apply for permits and plan for digging up streets. The process to replace old pipes can now be done in weeks rather than years.
Using CarboSeal, the pipe can be renewed from the inside. Instead of planning and digging up whole streets, existing manholes or small trenches can be used to renew the whole network. The minimal impact on activities overhead makes it easy to replace even the most challenging pipes under roads with heavy traffic, busy shopping streets, rail lines, or water.
No-Dig, no Interference
Trenchless Rehabilitation Solution
CarboSeal is a unique solution for rehabilitating district heating pipes that are structurally unsound. This non-invasive method ensures that pipe renewal will have minimal impact on the immediate surroundings, leaving other networks and structures in and on the ground unharmed.
