What Cgt Alkor does

CGT Alkor is a French industrial manufacturer of reinforced PVC membranes and single-layer PVC liners for swimming pools and adjacent surface applications, headquartered in Liancourt, France and operating as a wholly-owned subsidiary of Canadian conglomerate General Tower since 2019. Founded in the 1960s as a pioneer of PVC pool coatings in North America, the company is the product of a historical merger between French PVC film specialist Alkor and Dutch cable manufacturer Draka. The core technology is a proprietary three-layer reinforced PVC membrane structure with a woven polyester mesh grid providing dimensional stability and waterproofing, supplemented by an exclusive CERAM anti-slip grain technology compliant with EN 16165 Class C and Class 3 standards. The product portfolio spans residential membranes (Aquasense Signature, Aquasense, Aquastone, Aquadecor, Aquacolor), commercial/public-pool membranes (INFINITY, Aquaceram), single-layer liners sold B2B (3D Liner, RT4000AQ, RT4000, RT3000, Standard), the INFINITY DECK outdoor surface line, and industrial PVC films for signage/vehicle wrapping, nuclear and electrical protection, and theater/cinema projection surfaces.

CGT Alkor operates an exclusively B2B go-to-market: single-layer liners are sold only to specialized liner manufacturers, while reinforced membranes are distributed through a certified installer network (179 installers across all French metropolitan departments) and an international partner/distributor network spanning 40+ countries. The company supports its channel with proprietary digital infrastructure including the CGTower community matching platform (over 500 pool professionals and approximately 3,000 potential customers), a 3D product configurator, a digital asset management portal, multilingual SEO across 15 languages, and the CGT Alkor Academy installer certification program operating training centers in France, Italy, and Germany. Commercial customers include residential pool owners, commercial and public pool operators, lagoon/water feature developers, and industrial buyers in nuclear, electrical, signage, and entertainment segments. The company self-describes as #1 worldwide by production volume for PVC pool linings, supported by manufacturing facilities in North America and Europe and a 20-year commercial warranty on the INFINITY range and 15-year warranty on INFINITY DECK.

Expansion highlights6 records

Direct peers

• Renolit: German manufacturer of PVC pool liners and reinforced membranes, plus a wide range of films for outdoor and construction applications. The most direct global competitor to CGT Alkor in PVC pool waterproofing, serving the same certified-installer channel with overlapping product tiers.
• Achilles Corporation: Japanese PVC film and sheet manufacturer serving industrial, construction, and graphics end-markets. Comparable to CGT Alkor in flexible PVC film manufacturing capabilities, though focused primarily on Asia.
• ORAFOL: German manufacturer of vinyl graphic films, reflective materials, and industrial films. Directly comparable to CGT Alkor's Vinyl Graphics Films division in signage, vehicle wrapping, and industrial PVC film applications.
• Serge Ferrari: French manufacturer of flexible composite membranes for architecture, pools, and industrial applications. Overlaps with CGT Alkor in technical reinforced PVC membranes and shares a French manufacturing base, with comparable waterproofing and architectural end-uses.
• Cefil Pool: Spanish PVC pool liner manufacturer serving European and Latin American markets. Directly competes in the reinforced PVC liner category with similar product positioning to CGT Alkor's residential and commercial ranges.
• Haogenplast: Israeli producer of PVC pool liners and reinforced membranes exporting globally. Directly comparable to CGT Alkor in product format (multilayer reinforced PVC) and B2B distribution through liner manufacturers and pool installers.
• ELBE Blue Surface: German producer of pool liners and reinforced membranes, with a similar focus on certified installers and European B2B distribution. Comparable to CGT Alkor in product mix and target customer profile.

Broad incumbents

• Sika: Swiss construction chemicals giant with waterproofing solutions for pools, tanks, and wet areas. Competes with CGT Alkor at the project specification level but as part of a much broader chemicals portfolio rather than a specialist pool-membrane offering.
• Mapei: Italian construction chemicals leader with dedicated pool product lines including waterproofing mortars, sealants, and finishes. Overlaps with CGT Alkor in pool waterproofing end-use but competes via different technology (cementitious/chemical vs. PVC membrane).
• Avery Dennison: Global pressure-sensitive and vinyl film manufacturer with a strong graphics solutions business. Comparable to CGT Alkor's industrial vinyl graphics division as a much larger broad-line incumbent in self-adhesive vinyl films.
