POliner Sp. z o.o.

What POliner Sp. z o.o. does

POliner Sp. z o.o. is a Polish specialty manufacturer of CIPP (Cured-in-Place Pipe) liners and GRP (Glass-Reinforced Plastic) composite materials used for trenchless rehabilitation of underground sewer, water, and industrial pipelines. The company operates from a registered office in Chełmża and a production plant in Świecie that was expanded through the 2021 absorption of Mazur sp. z o.o.'s manufacturing activities. Its product portfolio spans eight CIPP liner families — POliner Glass, Glass Spiral, Felt, Felt & Glass, Intense, and the four POliner Hydro variants — covering diameters from DN150 to DN2000 and supporting UV, UV-LED, steam, and thermal curing methods. The company also produces GRP thin-walled manhole panel systems, TopHat lateral-connection profiles, and installation accessories.

POliner monetizes through direct B2B hardware sales of these liner systems to Polish water utilities, municipalities, and pipe renovation contractors, with quote-based pricing negotiated per project. The company is part of the BLEJKAN Holding Group, which gives it a captive in-group demand channel via Blejkan S.A. (construction/services) and Blejkan Construct SRL (Romania) while it also sells to independent contractors; documented international deliveries include a 1,266.5m sanitary sewer project in Abrud, Romania, and active marketing pursuit of the German market via a German-language website and RO-KA-TECH trade fair participation. Quality control and R&D are anchored by an in-house accredited Laboratory of Composite Materials (AB 1808, ILAC MRA), NIZP hygiene certification for potable-water liners, and a National Technical Assessment from the Building Research Institute, with ongoing EU co-funded R&D projects supporting modular automation and multilayer foil laminate development.

The go-to-market relies heavily on event-driven demand generation: POliner has served as General Partner, Gold Sponsor, Silver Sponsor, and Platinum Sponsor across the INŻYNIERIA Bezwykopowa, Bezwykopowa Rehabilitacja, and CIPP conferences from 2019 through 2026, with company experts delivering technical presentations on resin chemistry, CIPP quality control, and liner selection. The company maintains a multilingual Polish/English/German website with a renovation calculator integration and communicates EU-funded R&D milestones through public procurement announcements.

Direct peers

• Norditube Technologies (Aegion): Norditube is a Dutch/German manufacturer of CIPP liners (Nordipipe, Nordiliner), now part of Aegion. Direct competitor in the European CIPP liner market, comparable in technology (fiberglass and felt, UV-cured) and customer base.
• iMPREG GmbH: iMPREG is a German pioneer of UV-cured glass-fiber CIPP liners (iMPREG Liner System), now part of the Aegion group. Direct competitor in fiberglass UV-cured technology, serving the same European municipal and contractor customer base as POliner.
• Brandenburger Liner GmbH & Co. KG: Brandenburger Liner is a German CIPP liner manufacturer producing glass-fiber and felt-reinforced liners cured by UV and LED, directly overlapping with POliner's POliner Glass, Felt, and Felt & Glass product lines. Comparable product breadth, technology stack, and customer segment.
• RelineEurope GmbH: RelineEurope is a German CIPP liner manufacturer (Alphaliner, BrawoLin) producing UV-cured glass-fiber and felt liners, directly comparable to POliner's product portfolio. Competes for the same European municipal trenchless rehabilitation tenders.
• Saertex: Saertex is a German manufacturer of fiberglass-reinforced composites including CIPP liners (SAERTEX-LINER), directly competing with POliner's POliner Glass and Glass Spiral product lines in the European UV-cured CIPP market. Closely comparable in technology (fiberglass + UV/LED cure), target customers (utilities and contractors), and standards compliance.

Broad incumbents

• Trelleborg AB (Pipe Seals): Trelleborg is a Swedish industrial polymer group whose Pipe Seals division supplies sealing systems for pipe rehabilitation including CIPP-compatible products. Broader incumbent that overlaps with POliner in trenchless pipe rehabilitation but is not a focused CIPP liner manufacturer.
• Insituform Technologies (Aegion Corporation): Insituform, part of Aegion, is the global leader and pioneer of CIPP technology, offering both liner manufacturing and full installation services across North America, Europe, and beyond. A broad incumbent that overlaps with POliner on liner technology but operates at far greater scale across the full trenchless value chain.
• Sekisui Chemical Co., Ltd. Sekisui Chemical is a Japanese diversified conglomerate with significant CIPP liner operations through subsidiaries (e.g., SEKISUI Rib Loc), supplying trenchless rehabilitation products globally. Broad incumbent competing with POliner on liner technology but at much larger scale and broader geographic footprint.

Emerging players

• I.S.T. Innovative Sewer Technologies: I.S.T. is an Italian/German provider of CIPP technology and equipment for the European trenchless market. Overlaps with POliner in CIPP market positioning but is more focused on installation equipment and technology licensing than liner manufacturing.

Others

• Aliphatic Solutions: Aliphatic Solutions supplies specialty resins (including styrene-free systems) used in CIPP liner impregnation, comparable to the resin systems POliner specifies for its POliner Hydro product line. Adjacent supplier rather than direct competitor, but materially connected to POliner's value chain.
