Mapei’s Green Construction Boom Clouded by EU Price-Fixing Probe

Mapei’s Rise from Postwar Milan to Global Construction Chemicals Powerhouse

For most of 2025 Veronica Squinzi had reason to smile. Under the frescoed ceiling of Milan’s science museum, Mapei’s chief executive received the Leonardo da Vinci Prize, a honour reserved for historic family firms. Weeks later the mood shifted dramatically. As Mapei prepared to publish its annual results, the European Commission named the Italian group—alongside a handful of competitors—in a suspected price-fixing cartel for cement, concrete and mortar chemicals in three EU countries. The company denied the allegation immediately, but the sting was unmistakable.

Mapei’s story began modestly in 1937, when Rodolfo Squinzi, a decorator, founded a small paint business with seven employees. Post-war Milan, scarred by bombing, demanded vast reconstruction; orders poured in. Rodolfo’s son Giorgio, a chemistry graduate, took the helm in the 1970s and launched international expansion, starting with the adhesive used on the 1976 Montreal Olympics track. Today, with €4.4 billion in 2025 revenue—slightly up on the year—more than half of sales come from Italy and the rest of Europe, followed by North America. The group’s products have touched landmarks from the Colosseum to Notre-Dame.

CEO Veronica Squinzi and her brother Marco, who leads R&D, represent the third generation. Their strategy rests on relentless diversification: stadiums, mines, and the booming data-centre market all feature. “Between infrastructure expansion, new construction, and the fact every building needs maintenance at least every 20 years, our sector has long-term growth potential,” she told L’Express. Yet the same executive also sounded an alarm on the upstream chemical industry’s plight in Europe, calling on Brussels to preserve competitiveness amid soaring energy costs and cheap Chinese imports.

The Industry Forces Behind Construction Chemicals’ Ascent—and Its Peril

Where the Consolidation Race Leaves Mapei

The construction chemicals sector is in a wave of consolidation. French cement maker Vicat struck a deal with Belgian chemical group Koramic in 2024, while Saint-Gobain—after failing to buy Swiss rival Sika—has aggressively built a position through acquisitions, snapping up Chryso in 2021 and GCP in 2022. Mapei itself bought French firm Resipoly in 2021. Francesc Roca, an associate director at McKinsey, notes that the market remains fundamentally local: “The cost of transporting many materials can quickly become prohibitive relative to their value, so proximity to the customer is key.” This local nature gives established players with dense manufacturing footprints an edge over distant competitors, even as consolidation intensifies.

Why Construction Chemicals Is Shielded from China’s Disruption—for Now

The very factor that encourages consolidation also keeps Chinese competition at bay. Transport-intensive materials are less exposed to low-cost imports that have devastated other chemical segments. “Construction remains a fundamentally local market,” Roca emphasised. Where Chinese producers have flooded European chemicals with cheap volumes, construction chemicals are relatively insulated, allowing Mapei and its peers to maintain healthier margins.

The Renovation and Green Building Bonanza

Two structural tailwinds are independent of construction cycles. First, the EU aims to renovate 35 million buildings by 2030 under the revised Energy Performance of Buildings Directive, driving demand for sealants and insulation materials that Mapei already supplies. Second, the race to decarbonise cement—which accounts for roughly a third of global greenhouse gas emissions—is creating demand for additives that replace cement with lower-carbon alternatives. “Additives that accelerate production cycles have become a real sales argument,” said Alexander Keller, executive director at FTI Consulting. Mapei’s catalogue includes concrete additives and admixtures that directly address this need, positioning it well for green building mandates.

Brussels’ Crackdown and the Threat to a Family Legacy

The antitrust probe is the most immediate shadow. The European Commission suspects price coordination across three countries. If proven, fines can reach 10% of global annual turnover—potentially €440 million for Mapei. That would be a severe blow to a family-run business that prides itself on heritage and reliability. Even the allegation chips at the reputation painfully built since 1937. The investigation also arrives at a delicate moment: the broader chemical industry is lobbying Brussels to curb energy costs and to moderate the phase-out of free carbon allowances, both of which squeeze upstream suppliers. While construction chemicals may be a bright spot, the regulatory scrutiny and competitive headwinds on the wider chemical sector could unsettle investor confidence.

What Mapei, Its Rivals and Customers Should Watch as the Probe Unfolds

• For Mapei: The probe demands immediate legal resources. If authorities find evidence, the company may qualify for leniency if it cooperates early, potentially reducing a fine that could theoretically hit €440 million. Expect management to accelerate compliance and antitrust training, and to calibrate communications to emphasize the firm’s commitment to fair conduct. The coming months will also test whether the touted diversification strategy can cushion any financial penalty without jeopardising its acquisition-driven growth.
• For competitors: The cartel suspicion, if substantiated, may expose wider practices. Rivals named in the same communiqué face parallel risks. The episode could spur further consolidation as companies seek scale to absorb regulatory costs. Firms like Saint-Gobain and Sika will watch how the investigation reshapes the competitive landscape—especially as green building mandates open new bidding wars for specialist additives.
• For customers (construction firms and project owners): Keep a close eye on pricing and supply continuity. Even an unfounded probe can disrupt tenders and supplier relationships. With renovation mandates expanding, any distortion in the additives market could delay projects. Engage alternative suppliers and build contractual safeguards now, before the EU issues its final decision.
