What SEWERA does

Sewera Polska Chemia is a Polish building materials retailer and distributor founded in 1990 by Ireneusz Wolak and registered as a sole proprietorship (NIP 634-006-51-25) headquartered at ul. Kościuszki 326, Katowice. The company supplies construction chemicals, insulation, roofing materials, drywall systems, paints, tools, fastenings, workwear, and related goods to two parallel customer bases: individual DIY consumers undertaking home construction and renovation, and professional construction companies and trade contractors executing commercial projects. Revenue is generated through one-time product sales at unit-level pricing displayed in Polish zloty, with both net and gross (VAT-inclusive) prices shown, and order processing targeted at 24-48 hours.

The company's go-to-market is an omnichannel retail platform built on a regional footprint of seven physical branches - five in Silesia (Katowice, Sosnowiec, Dąbrowa Górnicza, Gliwice, Tarnowskie Góry) and two in Małopolska (Chrzanów, Oświęcim) - layered with a 24/7 e-commerce storefront (sklep.sewera.pl) and a dedicated B2B portal ('Strefa B2B'). Product assortment spans roofing (EPDM membranes from Hertalan, Resitrix/Carlisle), structural panels (OSB from Egger, Kronospan, Swiss Krono), drywall systems (gypsum boards from Rigips, Knauf, Siniat, including moisture- and fire-resistant variants), thermal and acoustic insulation (mineral wool from Climowool, Isover, Rockwool), decorative finishes (mosaic plasters from Atlas), polyurethane foams (Soudal, Tytan, Ceresit, Stalco), and additional categories such as electrical, lighting, tiles, paving, and PPE - aggregating product lines from more than 80 manufacturers.

Operations are supported by a staff of 270+ qualified specialists providing in-branch and remote technical consultation, alongside partnerships with three logistics providers (DHL for courier, InPost for parcel lockers, Raben for freight/pallets) for nationwide delivery, payment processing through ING Bank Śląski's iMoje platform, and multi-channel marketing spanning Facebook, Instagram, YouTube, LinkedIn, TikTok, a blog, and an email newsletter. The company is privately held with no institutional investors, no parent company, no subsidiaries, no disclosed revenue or funding activity, and operating geographies restricted exclusively to Poland.

Broad incumbents

• OBI Polska: German-originated DIY chain with a national Polish store network. Comparable assortment in building materials, paints, tools, and garden; broader geographic reach but similar DIY/professional customer mix.
• Bauhaus Polska: Swiss/German big-box home-improvement chain with Polish stores; comparable product categories including construction chemicals, insulation, drywall, and tools, with strong pro-customer orientation.
• Leroy Merlin Polska: Polish arm of the Adeo group and the country's largest home-improvement and building-materials retail chain. Directly competes with SEWERA across the same assortment (drywall, insulation, tools, chemicals) but operates at significantly larger scale with national coverage and stronger private-label economics.
• Castorama Polska: Polish subsidiary of Kingfisher, a national big-box DIY retailer overlapping on virtually every SEWERA category. Larger footprint and category breadth; serves as the dominant price benchmark SEWERA must position against.
• Bricomarché Polska: French DIY brand (Les Mousquetaires Group) operating a Polish chain of mid-sized home-improvement and building-materials stores. Closer to SEWERA's mid-market positioning than the largest incumbents, with overlapping assortment and similar dual-segment customer base.
• Bricoman Polska: Pro-focused trade and building-materials chain (Adeo group) targeting the same construction-company and contractor segment that SEWERA serves through its B2B portal. Comparable large-format wholesale-retail hybrid model.
• Hornbach Polska: German DIY chain with strong pro-customer positioning in Poland; overlaps directly with SEWERA on construction chemicals, insulation, roofing and drylining. Larger-format, project-focused retailer frequently used by the same trade contractors SEWERA targets.

Direct peers

• Majster Plus: Polish regional chain of building-materials and home-improvement stores serving DIY and trade customers. Closely comparable to SEWERA in store format, assortment breadth (construction chemicals, drywall, insulation, tools), and regional positioning.
• PSB Group (Grupа PSB / PSB Mrówka): Polish cooperative network of independent building-materials retailers carrying overlapping categories (drywall, insulation, roofing, tools) to both DIY and professional customers. Closest comparable to SEWERA in assortment mix and dual DIY/professional segmentation, with similar mid-sized regional footprint rather than big-box format.

Emerging players

• Tim Polska: Polish building-materials distributor and retailer focused on professional contractors and small commercial buyers. Overlaps with SEWERA's B2B segment on construction chemicals, fasteners, drywall, and tools, with growing online ordering capabilities comparable to SEWERA's B2B portal.
