What webac chemie does

WEBAC-Chemie GmbH is a German, family-owned specialty chemicals manufacturer founded in 1978, headquartered in Barsbüttel near Hamburg. The company develops, produces, and distributes chemical systems — primarily polyurethane-based injection resins, epoxy resins, acrylate gels, injection silanes, and silicate resins — used to waterproof, seal, repair, and reinforce buildings, civil structures, tunnels, dams, foundations, and historic monuments. Production is centralized at a single German facility certified to DIN EN ISO 9001:2015 and audited annually by TÜV Nord.

The company's portfolio spans roughly 80 products and injection equipment lines, sold as complete system solutions that pair chemical formulations with technical equipment (injection pumps, packers, tubes, swelling tapes, and joint profiles). Its primary customer base is B2B: construction professionals, civil engineers, infrastructure contractors, and heritage conservation specialists, served through direct sales channels (phone, email, contact form), tender-text integration with ausschreiben.de, and a distribution network spanning 50+ countries. Pricing is project-based and not publicly disclosed, with applications ranging from emergency water-stop in pressurized conditions to permanent structural sealing.

WEBAC differentiates through proprietary formulations, "Made in Germany" manufacturing, CE-certified products, technical association memberships (STUVA, WTA International, BuFAS, Deutsche Bauchemie), and a 45-year track record on high-visibility projects (Merowe Dam, Admiralspalast Berlin, Naples shaft sealing, Tyrol mountain station). Revenue is not publicly disclosed; the company is privately held by the founding family with management resting with Gudrun Schencking and Dr. Meik Weickenmeier as Managing Directors (Geschäftsführer/Geschäftsführerin).

Expansion highlights5 records

Broad incumbents

• Sika AG: Sika is a global construction-chemicals company offering waterproofing, concrete repair, sealants, adhesives, and injection products. Its portfolio is broader than WEBAC's, but it competes for the same contractors, engineers, and infrastructure projects.
• Mapei S.p.A. Mapei manufactures a broad portfolio of construction chemicals, including waterproofing products, concrete repair systems, grouts, sealants, and adhesives. It is larger and more diversified but serves many of the same building and infrastructure applications.

Direct peers

• MC-Bauchemie: MC-Bauchemie develops construction-chemical systems for concrete protection, repair, waterproofing, grouting, and structural rehabilitation. Its target customers and specialty formulation-led model closely resemble WEBAC's.
• Fosroc International: Fosroc supplies concrete repair and protection products, grouts, waterproofing systems, sealants, and injection materials. Its product offering and B2B focus on civil engineering and construction professionals make it a direct commercial analogue.
• Schomburg Group: Schomburg develops and distributes construction chemicals for structural protection, waterproofing, concrete repair, and renovation. Its specialized systems and target applications are closely aligned with WEBAC's resin and injection portfolio.
• KÖSTER Bauchemie AG: KÖSTER Bauchemie provides waterproofing and concrete-protection systems, including injection resins and products for foundations, basements, and structural repair. It directly overlaps with WEBAC's core waterproofing chemistries and applications.
• Remmers GmbH: Remmers produces specialist construction chemicals for building protection, waterproofing, concrete repair, floors, and timber preservation. It serves the same professional renovation and construction channels, although its portfolio is broader.
• ISOMAT S.A. ISOMAT manufactures waterproofing, concrete repair, flooring, tiling, and construction-chemical products for professional applications. Its product categories and direct B2B distribution model materially overlap with WEBAC's activities.
• Xypex Chemical Corporation: Xypex develops concrete waterproofing and durability technologies used in new construction and repair. Although its crystalline technology differs from WEBAC's injection resins, it targets the same water-ingress and structural-protection needs.
• Kryton International Inc. Kryton provides concrete waterproofing admixtures, surface treatments, and repair systems. Its application to concrete durability and water penetration is comparable, though WEBAC places greater emphasis on injectable resin systems.
