Freyssinet Serbia

The technique was patented by Eugène Freyssinet in 1928 and has been used on thousands of structures across the world by the STUP, the company created by Eugène Freyssinet in 1943 and which became Freyssinet in 1976. We offer a full range of post-tensioning systems, thus covering the entire market: B range, C range, F range, R range, X range and Freyssibar.
We have over 500,000 square meters of post-tensioned slabs, as well as numerous projects for post-tensioned beams and post-tensioning with Freyssibar bars or any other post-tensioning system.

Bearings, as a major component of the structures, with a decisive impact on their functioning, have the role of taking over the vertical and horizontal forces from the superstructure and transmitting them to the infrastructure, allowing translation and rotation movements. The choice, installation, monitoring, maintenance and replacement of right bearings requires the attention of a specialist, and our company, as an active player on the construction market, has developed a wide range of devices, thus offering the most suitable solutions to satisfy the needs of our customers.

Freyssinet has been manufacturing and installing expansion joints on road bridges, railway bridges and buildings all over the world for more than 50 years, and in Serbia since 2010. Freyssinet expansion joints are recognized for their durability, design and robustness. We offer support in order to identify the best solutions, a varied range of expansion joints perfectly adapted to different conditions and requests.

We offer a wide range of products and services dedicated to seismic protection marketed under the ISOSISM® brand:
– ISOSISM® SFX expansion joints
– ISOSISM® HDRB isolators
– ISOSISM® LRB lead core isolators
– ISOSISM® PS pendulums
– ISOSISM® STU connectors
– ISOSISM® FS isolators
– ISOSISM® FD fluid dampers
– ISOSISM® PDS and ISOSISM® DDD mechanical dampers

Post-tensioned slabs present numerous advantages:
– larger spans
– reduced slabs thickness and shorter execution timeline
– material savings and lower costs
– good seismic behavior
– reduced number of joints and vertical structural elements
– increased useful level height
– reduced overall height
– up to 20% reduced greenhouse gas emissions
– reduced structural weight and foundation loads

Stay cable and cable systems (cable-stayed bridges/pedestrian bridges, arched bridges, anchorage of high poles, covering structures for stadiums, sports halls etc.) are complex structures, with a constant evolution and significant progress in terms of functionality, strength and durability. Freyssinet has implemented in the region solutions and services that cover all stages: system design, installation, but also maintenance and monitoring of the system.

We deliver tailored solutions for:
– incremental launching/pushing concrete or metal bridge decks
– cast-in-place cantilever
– construction of bridges with form travellers (balanced cantilever bridges)
– “extradosed” type bridges
The solutions are adapted to each project, from the design to the actual execution of the works on site.
The lifting and handling of heavy structures are complex operations that are performed when other conventional installation methods are not possible, are too risky or too expensive and are only carried out by specialized companies.We deliver tailored solutions adapted to each project, from the design of the solution to the actual execution of the works.

Freyssinet anchoring systems, both temporary and permanent, are used to hold, restrain and support buildings, parkings, tunnels, basements, dams, wind turbines, towers or various civil engineering structures. These anchoring products are engineered systems used to stabilize the soil and/or fix the structures on the ground, allowing the load transfer.

Reinforced Earth® solutions have long been the first choice for engineers designing earth retention, retaining walls and ground stabilization, and for solving any soil-structure interaction design challenge.

Structural strengthening objective is to increase strength of the structure so that it can withstand loads that were not originally intended.
Freyssinet offers a wide variety of solutions for structural strengthening works:
– structural analysis for structural assesment
– additional post-tensioning
– dry shotcrete
– carbon fibres laminates Foreva® LFC
– carbon fibres-based fabric Foreva® TFC

For these projects inspections are carried out in order to evaluate the post-tensioned structures, and if the post-tensioning is not satisfactory or if the loads have increased compared to those originally designed, one of the repair and modernization solutions consists in carrying out additional external post-tensioning, a solution that allows the structure to be brought back to the required level of resistance and ensures the increase of the load-bearing capacity.

Due to the vast experience in this field, Freyssinet has developed a wide range of solutions and services for the maintenance and execution of repair works or replacement of stay cables and suspended cables at bridges.

As a specialized contractor, with extensive experience and numerous contracts for repair and replacement works of expansion joints and bearings, we can help to carry out maintenance and monitoring works, as well as their replacement, if necessary.

We offer a complete range of solutions for modernization, seismic retrofitting and repair works to the existing structures, from the design, manufacturing and in-house testing of the proposed system, to its installation.

We offer our clients a complete range of solutions for repairs and strengthening of industrial structures:
– structural assessment
– solution design for repair and strengthening works
– implementation of solutions for repair and strengthening works
