technical and commercial issues.
The technologies on offer from Fluvius include
full lining systems for pipelines in diameters from 28
mm up to 800 mm using CIPP technology as well
as lateral lining and lateral sealing systems that can
negotiate bends up to 90o and diameter transitions
in a single installation. Liners are also offered
for localised repairs (‘patches’) where full length
rehabilitation is not required in diameters from 100
mm up to 900 mm.
In larger man-entry diameters Fluvius also offers a
range of Kevlar/EPDM manually installed pipe joint
seals. For manhole rehabilitation the company has
cementitious grout lining options offering structural
repair and saltwater resistance, as well as localised

EUROPEAN REHABILITATION
TECHNOLOGY GOES GLOBAL
Fluvius GmbH of Germany, in association with its
Eastern European partner Sanikom in Slovenia,
sells products primarily for the trenchless repair
of wastewater pipe systems with the product focus
being mainly on full-length and localised repair up to
a pipe diameter of 800 mm.
The company’s range includes the full spectrum
of consumables, such as resin systems, liners,
fibreglass complexes, renovation packers and
products for flow control and test technology as
well as accessories, that are required for trenchless
installations in wastewater systems, as well as
specialist technical equipment that is designed
either in-house to the highest quality standards
or as products sourced from other renowned
manufacturers. The various renovation methods
offered carry a range of globally recognised industry
approvals and certificates.
Fluvius can provide clients with solution
proposals and entire systems for the renovation and
maintenance of defective wastewater pipes. With
