The 1st Relining Solution for District Heating Pipes

CarboSeal - Relining for District Heating
01
Benefits

Fast

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.

Simple

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.

Sustainable

Using CarboSeal, the host pipe remains in the ground, with no need to dig it out, refill or recycle to rehabilitate old pipes. By avoiding excavation, the carbon footprint of producing, installing and refilling is reduced by at least 80%.

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.

Closing a Gap in the Market

Relining for District Heating
Until now, the market could not offer a liner for trenchless rehabilitation of district heating pipes. The materials traditionally used for pipe lining cannot withstand the high-heat, high-pressure corrosive environment in and around district heating pipes. CarboSeal is the solution.

New from Old

Taking over the Workload of the Host Pipe
The system is designed to completely take over the workload of the host pipe, leaving it fully renewed. Distances of up to a few hundred metres can be rehabilitated in one working day, with little or no excavation.
