Winkler

What Winkler does

Winkler is an Italian specialty chemicals manufacturer specializing in waterproofing, protective, and finishing solutions for the construction industry. Founded in 1987 per firmographic data (the company history block records 1996 as the formal launch of the WINKLERSAFE sustainability-driven approach), the company is headquartered in Milan at Via Privata Reggio n. 3 and operates as a privately held S.r.l. with €500,000 of fully paid share capital. The product portfolio exceeds 200 technical solutions spanning liquid waterproofing membranes (the WINGUM PLUS H2O and ONE System platforms), polymer-bitumen membranes across multiple lines (EXPERTA, FLEXA TECH, COVERSUPER, COVERGUM, COVEREXTRA HP, COVERBOND, COVERBLOCK, COVERSTICK, TAGLIAMURO), resin-based flooring systems (UNIBAR, WINPAINT, WINPOX, WINLIVEL), cement-based waterproofing products (BOND CEMENT, WINTAPLAST, SKERMO TERRAZZE), and adhesion promoters (WINGRIP NEXT, WINGRIP BITUMINOSO). All formulations follow the WINKLERSAFE philosophy, meaning they are water-based or 100% solvent-free, and over 70 products hold EMICODE EC1 PLUS certification.

The company serves three primary end-markets — residential, industrial, and commercial construction — through a horizontal segmentation model that targets waterproofing, adhesion, chemical resistance, energy efficiency, and structural protection pain points. Reference projects span sports infrastructure (Stadio Euganeo, ~3,000 m² of ONE Flooring; Golden Goose Arena), retail (Zara Parma), aviation (Hangar Linate Prime), industrial (BRC Gas Equipment), municipal (10,000 m³ detention tank in Parabiago), hospitality (OHIMA Positano, Resort Malcesine on Lake Garda), and international real estate (Allen Street Property, NYC). Winkler monetizes primarily through one-time product sales distributed via a network of official foreign distributors (UK via OKCS Supplies Ltd, Ireland via Evex Ltd, Malta via The Resin & Membrane Centre, Cyprus via DomoLine Ltd) and specialized construction materials distributors across Italy, with no direct e-commerce. Revenue is supplemented by technical training services delivered through the Winkler Academy platform (Master Course certification for applicators, specifiers, and distributors). Pricing is opaque (not publicly disclosed), with unit-pricing per kg/m² consumption and channel-based determination.

The firm operates internal R&D and manufacturing in Italy, and has compiled an unusually broad regulatory footprint including ISO 9001:2015, ISO 14001, EAD 030350-00-0402 (W3 25-year durability for WINGUM PLUS H2O), UNI 11928-1, UNI EN 14891, UNI EN 1504-2, UNI EN 13813, UNI EN 13501-5 (Broof t2 fire classification), ASTM D6083, ANSI A118.10/A118.12, CRRC cool roof ratings (SRI 108 for WINGUM PLUS H2O Reflex), LEED/BREEAM/DGNB/CAM support, Miami Dade County approval, California Title 24 compliance, and an EPD for recycled-content reinforcement fabric.

Expansion highlights6 records

Broad incumbents

• Sika: Swiss-listed global construction chemicals major with a deep waterproofing portfolio (SikaRoof, Sikalastic liquid membranes, bituminous systems) plus concrete repair, flooring, and sealing. Broad incumbent operating at much larger scale across the same waterproofing and resin flooring categories Winkler addresses.
• Bostik (Arkema): Global adhesives and sealants business of Arkema, offering construction sealants, waterproofing, and tile adhesives. Broad incumbent because Bostik overlaps with Winkler's adhesive/sealant and under-tile waterproofing product lines (WINGRIP, Bond Cement) as part of a much larger diversified adhesives portfolio.
• BASF Master Builders Solutions: Global construction chemicals division of BASF offering waterproofing, concrete repair, sealants, and resin flooring. Broad incumbent because Master Builders Solutions participates across the same waterproofing and resin flooring categories Winkler serves, with much larger R&D resources and global distribution.

Direct peers

• Tremco Construction Products Group: Specialty construction products group focused on waterproofing, sealants, and coatings for roofing and building envelope, including liquid-applied systems. Direct peer because Tremco competes with Winkler in liquid roof waterproofing, joint sealants, and below-grade systems, with a similar specification-driven GTM toward architects and contractors.
• Mapei: Italian-headquartered global leader in construction chemicals, including liquid waterproofing membranes, adhesives, and resin flooring systems. Directly comparable as a broad-range specialty waterproofing manufacturer with similar product architecture (liquid membranes, cement-based systems, resins) and overlapping customer base of contractors, distributors, and specifiers.
• Fosroc: International specialty construction chemicals manufacturer offering waterproofing membranes, concrete repair systems, sealants, and resin flooring, with a comparable mix of liquid-applied and cementitious solutions. Direct peer because Fosroc serves the same contractor and specifier base in commercial, industrial, and infrastructure waterproofing segments.
• INDEX S.p.A. Italian specialist in bituminous and synthetic membranes for roofing and below-grade waterproofing, with a comparable product mix in bituminous sheets and liquid systems. Direct peer because it competes head-to-head with Winkler's COVER/EXPERTA/FLEXA TECH bituminous membrane lines and serves similar roofing and infrastructure applicators.
• Kemper System: German-based specialist in cold-applied liquid waterproofing resins and membranes for roofs, balconies, and parking decks. Direct peer because Kemper System's liquid-applied waterproofing technology and project-led GTM closely match Winkler's WINGUM PLUS H2O and ONE System liquid waterproofing offering.
• Soprema: French-headquartered specialist in waterproofing systems, including SBS/APP modified bituminous membranes, synthetic membranes, and liquid-applied systems. Direct peer because Soprema's product architecture (bitumen sheets plus liquid waterproofing) closely mirrors Winkler's COVERGUM/EXPERTA plus WINGUM PLUS H2O portfolio, and the two compete for the same roofing and below-grade project specifications.
• Polyglass: Specialist manufacturer of modified bitumen and synthetic waterproofing membranes, now part of the Mapei Group, with strong presence in the US and Europe. Direct peer because Polyglass's modified bitumen membrane offering overlaps directly with Winkler's COVER/EXPERTA/FLEXA TECH bituminous lines and competes for the same roofing contractor and distributor channels.
