Hobas

What Hobas does

Hobas is a Swiss-origin industrial manufacturer of centrifugally cast glass fiber reinforced plastic (GRP) pipe systems, founded in 1957 in Basel and now operating as a brand under Amiblu Holding GmbH, a 50:50 joint venture between Wietersdorfer Holding (Austria) and Amiantit Europe formed in 2017 with European Commission approval. Its core technology is a 100% computerized centrifugal casting process that builds GRP pipe walls layer-by-layer from chopped glass fibers, thermosetting resins (unsaturated polyester or vinylester), minerals, and silica sand, using centrifugal forces up to 75g to produce void-free pipes with uniform wall thickness and consistent outer diameter. The product portfolio covers non-pressure pipes (DN 200-3600, PN 1 bar), pressure pipes (up to 25 bar), the PU Line abrasion-resistant variant, jacking pipes for microtunneling, couplings, fittings, manholes, and custom storage tanks, with stiffness classes up to 30,000 N/m² (and up to 1,000,000 N/m² for jacking applications).

Hobas serves primarily municipal water utilities and wastewater authorities, with secondary applications in hydropower penstocks, irrigation, and trenchless civil infrastructure. Its customer base spans 125+ countries with a reference database of 30,000+ projects accumulated over more than 60 years, and its value proposition centers on 150+ year service life, corrosion resistance, leak-tight air-tested joints, fast installation (days vs. months for concrete), and compliance with European standards (EN 14364, DIN 19523, EN 1092). The revenue model is hardware sales of customized pipe and fitting systems, with pricing varying by diameter, pressure class, stiffness, and project specification; pricing is not publicly disclosed.

Distribution is split: in Europe, sales are handled exclusively by Amiblu through regional sales offices in Austria, Germany, Switzerland, Poland, and France, supported by manufacturing in Germany, Poland, Spain, and Romania and an R&D center in Norway; outside Europe (USA, Canada, Latin America, Mexico), Hobas is sold through licensed distributors. The Amiblu Group employs approximately 1,500 people worldwide, and the group is governed by Austrian law with its registered seat in Klagenfurt.
