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 manhole leak sealing systems. Fluvius offers ‘patch’ repair localised lining systems Commenting on the event Sebastian Schmitz, Managing Director of Fluvius said: “Trenchless Middle East 2011 will give us another springboard into areas of the world that require the sort of technology we have on offer. Our technical Full length lining utilising an inversion drum installation technique team will be at the event offering current and any potential new clientelle guidance through the Fluvius range of systems.” nEUROPEAN REHABILITATIONTECHNOLOGY 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.
