Origin
Founder Kaspar Winkler came from a poor Austrian shoemaker family. After immigrating to Switzerland, he started out as a stonemason and formulation experimenter, initially developing granite protectants Conservado and Purigo, and experimenting with mortar waterproofing additives. In 1910, he founded Kaspar Winkler & Co. in Switzerland, inventing the quick-setting waterproofing agent Sika-1, initially targeting roof and building leak repair via injection. At the time, building leakage repair was a widespread essential need but the market was highly fragmented. He bet on a technology business where a single formulation could solve a world-class leakage problem, rather than engineering contracting.
Milestones
1917
Founding and Consecutive Loss Period Turning Point
In 1917, Kaspar Winkler & Co., the predecessor of the company founded by Kaspar Winkler in Switzerland in 1910, saw its invented Sika-1 quick-setting waterproofing agent initially used for roof and building leak repairs. The company suffered losses for seven consecutive years and fell into near despair during World War I, illustrating that the cycle from technological invention to commercial validation far exceeded expectations. The founder survived the darkest startup period through continuous investment and technical obsession.
1918
Gotthard Tunnel Waterproofing Project Turning Point
In 1918, Swiss Federal Railways prepared for the electrification retrofit of the Gotthard Tunnel, where severe long-term water leakage inside the tunnel had become a world-class challenge. Sika's waterproofing agent successfully resolved the issue, and the railway department subsequently applied the technology to waterproof 67 tunnels. Sika leaped overnight from a small local workshop to a national infrastructure supplier and turned a profit, marking the first decisive anchor order in its century-long history.
1930
Overseas Expansion and Franchise Failure Failure
Sika's initial attempt at overseas franchising failed, after which it adjusted its strategy to a local subsidiary model: establishing subsidiaries in the UK, Italy, and France between 1926 and 1928, led by the founder's son-in-law, Fritz Schenker, to drive global layout. By the 1930s, 15 subsidiaries had been established in Europe, the US, Argentina, Brazil, and Japan, replacing out-of-control franchise licensing with a controllable direct-operation model.
1960
Survival Crisis Triggered by Economic Overheating Failure
In the late 1960s, the Swiss economy overheated severely, plunging the company into crisis: the newly built Düdingen plant ran over budget, the construction business suffered heavy losses, and massive warranty claims arose in the German and Scandinavian markets, pushing the company to the brink of bankruptcy. Afterward, the company reflected deeply and cut its construction business, forging the Sika spirit centered on collective responsibility, optimism, and unity during the 1970s recession, thereby completing strategic focus.
1980
Listing and Entry into the Automotive Industry Turning Point
In 1971, Sika went public on the Swiss Exchange (SIX: SIKA), transitioning from a family business to a public company. In 1980, it launched the high-performance polyurethane adhesive Sikaflex, entering the automotive manufacturing sector for applications such as windshield sealing and bonding. This broke its absolute dependence on the single construction industry, hedging against the construction cycle using industrial adhesive operations and significantly boosting counter-cyclical resilience.
1995
Divestment of Non-Core Businesses and Growth Recovery Turning Point
In the 1990s, weak corporate profitability forced the company to exit non-core businesses such as sewer pipe robots and road products, and even prepare to sell the sealing membrane business. After refocusing on core chemicals, growth resumed: between 1990 and 1995, 16 new subsidiaries were added, revenue grew from CHF 2 billion to over CHF 4.6 billion, and headcount increased from 8,000 to 13,000, proving that subtraction creates more value than blind diversification.
2023
M&A Integration and Becoming a Global Leader Growth
Entering the 21st century, Sika used M&A as its growth engine: completing 36 acquisitions from 2000 to 2008, acquiring Parex in 2019, and finalizing MBCC in 2023—its largest acquisition ever—to strengthen concrete admixtures. Post-2015, it accumulated over 25 additional acquisitions, 40 plants, and more than 400 patents. The business focuses on five core capabilities spanning sealing, bonding, damping, reinforcing, and protecting from basement to roof, capturing an approximate 12% market share and topping global construction chemicals.
Turning Points
- The 1918 Gotthard Tunnel waterproofing project allowed a local workshop with 7 consecutive years of losses to transform into a national infrastructure supplier.
- After the initial failure of overseas franchising in the 1920s, Sika shifted to a local direct subsidiary model, mastering the pace of globalization thereafter.
- The near-bankruptcy crisis in the late 1960s forced Sika to cut its construction business, reshape the Sika spirit, and focus on its chemical core.
- Entering the automotive industry with Sikaflex in 1980 eliminated single reliance on the construction industry and built counter-cyclical resilience.
- Divestment of non-core businesses like sewer pipe robots in the 1990s preserved resources, while the sealing membrane business—almost sold off—later became a core asset.
Failures & Pitfalls
- From 1910 to 1917, the company suffered losses for seven consecutive years and nearly collapsed during World War I.
- The initial overseas franchise attempt in the 1920s failed, forcing a shift to a direct subsidiary operating model.
- Economic overheating in the late 1960s led to budget overruns at the new Düdingen plant, heavy losses in construction, and massive warranty claims in Germany and Scandinavia, pushing the company to the brink of bankruptcy.
- Weak profitability in the 1990s forced the exit from sewer pipe robots, road products, and other businesses, and nearly led to the sale of the sealing membrane business.
关键成功要素
- The single hit product Sika-1 waterproofing agent precisely targeted the national engineering pain point of tunnel electrification water leakage, achieving fame in a single battle.
- An internationalization path based on local direct subsidiaries rather than franchising, locking down formulation know-how and delivery quality control.
- A strategic focus on five core technologies extending from waterproofing agents to concrete admixtures, sealants, and adhesives, maintaining restraint without losing focus.
- Continuous expansion through M&A after listing in 1971: 36 acquisitions from 2000 to 2008, and MBCC in 2023 as the largest single transaction.
- Entering automotive industrial adhesives in the 1980s to hedge construction cycles with industrial business, weathering multiple recessions.
- The Sika spirit employee culture formed after crises, supporting a century-old enterprise to survive major shareholder games and family succession.
Lessons
- A single national engineering order is enough for a tech-oriented small workshop to complete a brand leap, but it must be able to afford the seven-year validation period.
- The moat of a formulation-based business lies not in the number of patents, but in localized production, construction methods, and sticky customer relationships.
- All-encompassing diversification (construction, robots, road products) drags down profitability; subtraction focusing on the core chemical business is the path to survival.
- Franchising is prone to loss of control in multinational expansion; direct subsidiaries are slower but guarantee technical delivery quality and long-term brand equity.
- Governance in a century-old enterprise (family succession, the Sika control battle around 2015) is just as decisive for survival as core business focus.

Competitors / Peers
The global construction chemicals market is approximately CHF 100 billion, with Sika ranking first at around 12% market share. Key benchmarking players include BASF Construction Chemicals (subsequently integrated into MBCC, acquired by Sika in 2023), Saint-Gobain's Weber and Chryso, Henkel's Industrial Adhesives division, Dow, and China's waterproofing leader Oriental Yuhong. Sika continuously captures market share through acquisitions and localized production models. Following the integration of MBCC in 2023, it firmly holds the global top spot in concrete admixtures while competing head-to-head with Henkel and Saint-Gobain in niche segments such as windshield bonding using polyurethane adhesives like Sikaflex. In reality, Sika studies the formulations and distribution networks of all building materials chemical giants.
