Geberit Drainage Systems
Within an ever more competitive culture, installers
and specifiers are continually striving to reduce costs,
labour and materials used in the construction process.
Flexibility of any construction system is paramount in the
reduction of many cost factors, allowing a more open
view to design and installation.
Geberit HDPE drainage provides installers and specifiers
with a wholly more flexible, multi-application drainage
solution. The system incorporates several jointing methods
that present many advantages over other piping systems.
It allows the installer to choose a preferred or appropriate
jointing method as well as aiding pre-fabrication of the
drainage system off-site. Jointing methods are fast and
easy - installers can become proficient in installation after
training provided on-site or at Geberit’s Training Academy.
