What Does Wrapping Technology Mean?

Wrapping technology describes a patented type of pipelining installation developed by the German company Brandenburger Liner.

The technique consists of resin impregnated glass fiber composite material wrapped around a transparent inner foil to create a durable pipe liner. Wrapping technology is considered to be a structural liner since, once it cures, it creates a new pipe within the host pipe.


Trenchlesspedia Explains Wrapping Technology

Pipe liners are a popular form of trenchless sewer rehabilitation. Traditional pipe liners typically consist of resin saturated felt material. The felt tube is then inverted into the pipe and pressed against to the inner walls of the host pipe to form a permanent bond.

Wrapping technology, on the other hand, is constructed from resin impregnated glass fiber composite material which comes available in tube-like laminated rolls. The pre-impregnated rolls are inserted into the host pipe and hardened with UV light via a remote device inserted into the pipe.
