CC-GRP Pipe Systems

Amiblu is a joint venture of two brands with a rich history.

Amiblu is a 50:50 joint venture whose goal is to develop and deliver world-class GRP pipes and fittings to sustainably solve the world’s water and sewer challenges. Amiblu combines Amiantit Europe and its Flowtite Technology, and Hobas Europe, part of WIG Wietersdorfer Holding, and is the specialist in drinking water, irrigation, storm- and wastewater, hydropower and industry.

The two businesses have distinct expertise that complement each other perfectly. Hobas is a leader in centrifugally cast pipe systems, and Flowtite in continuous filament wound pipe systems. Amiblu’s headquarters is in Klagenfurt, Austria, and the company has production facilities in Germany, Spain, Poland and Romania. It has a R&D centre in Norway and employs around 1,500 people.

Our licensee partners around the world, plus an extensive network of sales and engineering offices, add a further global dimension. The result is that wherever our customers require a sustainable, high performance solution, Flowtite and Hobas come together to deliver precisely what they require.


It all began quite modestly at the Basle Dye Works in 1957 where wooden cylinders were employed for the dyeing process. These kept splintering and deforming after some time putting the expensive textiles at risk. Seeking a suitable replacement for the cylinders, the factory’s engineers developed a centrifugal casting method using glassfiber reinforced plastics (GRP). Thanks to the method and material, they achieved perfectly concentric cylinders with a precise outer diameter and smooth surface – just as required.

GRP had previously been used for shipbuilding, automobile and aircraft industry. However, its resistance to both corrosion and chemicals also made the material highly suitable for other applications. The Swiss, renowned for their vision and pioneering spirit, recognized its benefits and soon employed centrifugally cast pipes for conveying water – a new company was born: Hobas. The pipes laid at these early times are still in use today. Step by step, the products were improved, the manufacturing process was automated, the product range extended, and tailor-made fittings were added to the portfolio.
