The waterproofing works market in France

Waterproofing works in France rely on three product families: bituminous membranes, synthetic PVC or TPO membranes, and liquid waterproofing systems. According to Eurostat, France exported 56,390 tonnes of bituminous waterproofing rolls in 2025, worth €53.8 million. Synthetic membranes are gaining ground in the renovation of industrial roofs, according to Trends (June 2025), and Soprema has launched a liquid waterproofing plant near Strasbourg, according to Le Journal des entreprises (March 2024).

Among waterproofing contractors in France, SMAC claims 2,300 employees, 63 sites and more than 5,000 projects a year. On the manufacturing side, Soprema, described by Le Journal des entreprises (February 2024) as the world’s number 3 in insulation and waterproofing materials, reports 5,700 employees and 11 production units in France in 2025. The Alsace-based Galopin group, which has created a waterproofing and civil engineering division, generated €61 million in revenue in 2024, according to Le Journal des entreprises (February 2026).

Yes: for bituminous waterproofing rolls, France exports more than it imports. According to Eurostat, French exports reach €53.8 million in 2025, after €60.0 million in 2024, for 56,390 tonnes. Imports fall to €30.0 million, against €49.0 million in 2024, a drop of about 39% (calculated from Eurostat). The trade balance of these membranes, used in waterproofing works in France, is thus in surplus by about €23.8 million in 2025.

Energy renovation supports roof waterproofing works in France because insulating a flat roof requires its waterproofing to be redone. According to Zepros Métiers réno (May 2025), the roof accounts for 30% of the energy losses of a detached house, and 85% of flat roofs are inaccessible. Le Journal des entreprises (March 2024) recalls the government target of 700,000 renovations a year and reports that Soprema is building a 30,000 m² super-insulation plant in Sausheim (Haut-Rhin), intended notably for roofs.

Tunnels and underground structures are a major outlet for waterproofing works in France. According to Le Moniteur (October 2025), the Grand Paris Express (the Paris metro extension) comprises 200 km of new metro lines and 68 stations. On the Lyon-Turin base tunnel, at Saint-Julien-Mont-Denis (Savoie), a 3 mm waterproofing membrane is laid in 150 kg rolls, at about 200 m² a day, on a lining project worth €228 million excluding tax, according to Le Moniteur.
