Freysas Freyssinet

What Freysas Freyssinet does

Freysas Freyssinet (legal name: Freysas Freyssinet Yapı Sistemleri San. A.Ş.) is an Istanbul-headquartered engineering and construction services company founded in 1988. It operates as the Turkish branch of Soletanche Freyssinet SAS, which is in turn part of the VINCI Group, one of the world's largest construction conglomerates. The company specializes in post-tensioning (prestressing) technology and applies it across bridges, viaducts, buildings, and cylindrical structures, with complementary offerings in cable-stay systems, seismic isolation devices, incremental launching and balanced cantilever construction methods, and structural repair/strengthening services delivered through its subsidiary Hebetec Engineering.

The core technology platform rests on Freyssinet's proprietary HD Stay Cable System (a patent-protected parallel multistrand configuration with individual strand installation, corrosion protection, and replacement) and the ISOSISM portfolio of seismic protection devices including fluid dampers, lead rubber bearings (LRB), high damping rubber bearings (HDRB), pendulum bearings, and shock transmission units. Notable technical outputs include 24,000+ meters of incrementally launched viaducts, 50+ post-tensioned cylindrical structures, the 176-cable / 8,400-ton stay cable system on the Yavuz Sultan Selim Bridge, and the 70,000 m² post-tensioned slab system for Vakıfbank's 59-storey headquarters.

Revenue is generated through project-based, quote-priced enterprise contracts with government infrastructure agencies, general contractors, and large private owners across four streams: infrastructure construction services (bridges, viaducts), engineering and design services (method engineering, casting curve analysis, independent design checks), structural component supply (post-tensioning materials, bearings, expansion joints, seismic devices), and repair/maintenance services (seismic retrofit, bearing and joint replacement, concrete strengthening). The company markets through its corporate website, LinkedIn presence, and the Freyssinet Group YouTube channel, and engages clients via direct enterprise field sales on long sales cycles. Service geographies span Turkey, Azerbaijan, and Karabakh.

• Freyssinet (Group): Global parent organization and direct peer in post-tensioning, stay cable, and seismic protection technology. Freysaş is the Turkish branch of this group and shares its proprietary technology (HD Stay Cable System, ISOSISM), making it the most directly comparable entity for technology and product benchmarking.

Broad incumbents

• Soletanche Bachy: Sister company within Soletanche Freyssinet (VINCI), focused on geotechnical and foundation engineering. Operates broadly in the same civil engineering space as Freysaş and provides context on how the parent group's strategy positions different specialist subsidiaries.

Regional players

• Tekfen Construction: Major Turkish general contractor active in infrastructure, bridges, and industrial construction. Comparable to Freysaş in the Turkish market on large infrastructure tenders, though as a general contractor rather than a specialist post-tensioning subcontractor.
• Enka Insaat: One of Turkey's largest engineering and construction groups, active in power plants, airports, and large infrastructure. Comparable in scale of landmark projects and exposure to Turkish public/private infrastructure spending.
• Yuksel Proje: Turkish engineering and consulting firm specializing in bridges, viaducts, highways, and structural design. Comparable as a domestic Turkish peer in the bridge and viaduct design/execution market.

Others

• Hebetec Engineering: Specialist subsidiary of Freyssinet Group for integrated heavy lifting and handling solutions. Listed as a standalone comparable to capture the lifting/jacking/sliding subset of Freysaş's service portfolio.
