What is Lebit?
Composition
Function and principle
Advantages
Applications


Invented by Shell in the 60s

Lebit stands for Leicht Bitumen

It is a completely seamless insulation for heat conducting pipes


Comprises 3 natural raw materials:



Cork
Constantly growing natural product (cork oak)
Cellulose
Raw material made from wood fibres
Bitumen
Natural product that has been in use for the past 5000 years and is found in nature
Processed without any chemical additives


Lebit is thermo-elastic that is a liquid when cast and hard and elastic when cooled.

When used in heating pipes, the product creates a flexible section where it is applied, while the hard sections remain in place just a few centimetres further.

This hard and flexible combination can be repeated indefinitely in the pipes. The properties of Lebit never change.

Heated pipes can contract or expand without any pressure as the pipe 'swims' in local fluid Lebit.


Seamless insulation (no cold bridging)
Resistant against groundwater
Completely water impermeable and thus resistant to corrosion
High heat insulation
Electric isolation
Flexible and slidable at the bearing point
Internally flexible; stable external shape
Can be processed during renovations under working conditions
No sleeve connections, no support points (cold bridging)
Also suitable for temperatures up to 200°C
100% recyclable
Lebit is made from completely natural materials


Future-oriented, environmentally friendly, affordable renovation technology

Processing properties of Lebit

Lebit combines the various properties of the raw materials to create a unique product

The result is a homogenous, thermoplastic mass that can be poured directly from the thermo-mixer into prepared lost shells due to its viscosity

After a few hours, the trench can be filled again with the original soil

The renovation is then complete. The heating pipes can be used throughout the renovation process
