What Kaczmarek Malewo does

Kaczmarek Malewo (Kaczmarek Malewo Spółka Komandytowa) is a Polish family-owned manufacturer of plastic installation systems founded in 1985 and headquartered at Malewo 1, 63-800 Gostyń, Poland. The company produces pipe, chamber, tank, fitting, and rainwater-management systems for water supply, sewage, gas, drainage, cable protection, and roof-drainage applications across nine proprietary product families — DIAMIR (PP injection-molded sewage chambers and tanks), K2-Kan and K2-Kan XXL (PP co-extruded structural-wall pipes up to 3000 mm), TYTAN (PE-HD/PE 100/PE 100-RC pressure pipes for water, sewage, and gas, including PAS 1075 Type 3 for trenchless installation), FONICA (PP-HT low-noise internal sewage, <10 dB with Bismat 1000 clamp), K2-Dren, K2-Kabel, Hydro-Box, and Karolina (PVC-U gutter and soffit). Manufacturing is based in a 96,000 m2 Gostyń site with 11,100 m2 of covered production and warehousing plus a second Piaski production facility established in 1997.

The company's technology stack centers on co-extrusion (for structured-wall pipes), injection molding (for DIAMIR chambers), and specialized PP-HT formulations, with documented performance attributes including 100-year predicted service life, 65% lighter weight than monolithic-wall equivalents at equivalent stiffness, and certification to multiple ITB-KOT, IBDiM-KOT, IK-KOT, ISO 9001, ISO 14001, EN, and PN standards.

Kaczmarek Malewo monetizes exclusively through hardware sales (B2B unit pricing with publicly downloadable catalogs and dated price lists) via a two-tier GTM motion: a network of over 200 Polish distributors plus a proprietary e-Handel ordering platform for direct enterprise orders, supplemented by international trade show presence (IFAT Munich, Wod-Kan Bydgoszcz, Roof Expo). The customer base is segmented vertically across municipal water and sewage companies, construction/infrastructure contractors, industrial facilities, and residential developers, with an explicit export motion evidenced by an eight-person foreign sales team and presence in markets including Saudi Arabia. Revenue is not publicly disclosed; the company remains a privately held Spółka Komandytowa under founding-family control with no institutional investors, subsidiaries, or M&A activity on record.
