|Many concrete repair systems, i.e. for
sewer pipelines, expose workers to solvent-based resin material in
the pre-set stage. This project has developed a new high-strength
system (DUREP) that relies on fully mineral, cement-based material
and completely eliminates this hazard from the working environment.
In addition, the material offers improved corrosion protection and
is suitable for both pumping and spraying. It is fully biodegradable.
The partners have already seen economic gains
as a result of using these materials. But the long-term stability
and reliability of the system has to be proved first on small sewer
rehabilitation projects. Once this has been achieved, significant
growth in the use of DUREP is expected.
DUREP could also feasibly be used as a
protective coating for outside concrete structures, especially those
exposed to chlorides such as seawater.
