Freyssinet manufactures and supplies a wide
range of accessories (bearings, expansion joints, etc.) and earthquake
protection devices that comply with the most stringent standards.
The main structural accessories offered by Freyssinet, Inc. are:
Bearings, which transfer major vertical
loads, such as between a deck and its piers

Expansion Joints, which ensure a
continuous road surface, such as between a main deck and its end spans,
CIPEC expansion joints are designed to enable continuous traffic between
two structures, accommodating structural movements due to creep, shrinkage
effects, temperature variations and deformations under live load. They
are suitable for all reinforced concrete, prestressed concrete, composite
and steel structures, and particularly for bridge decks. CIPEC expansion
joints are also designed to allow sufficient vertical movement so that
bearings can be replaced without needing to disassemble the expansion joint.
They enable drainage of runoff water and they are designed to minimize
The current family of Freyssinet’s expansion joints has been in use for
more than 30 years and has the following to offer:
Excellent traffic control
High corrosion resistance
No horizontal reaction
Protection of surface under joints
Good resistance to heavy duty & frequent
Adaptability to all types of surface structure
Low servicing and maintenance
Easy and quick replacement (without damaging
the existing structure)
All joints come with optional accessories to ensure water-tightness and
effectiveness over footpaths, such as pavement joints, end section upstands

Flat Jacks, which are used to induce
movement and.or apply high forces in a restricted space.
The Freyssinet flat jack is a thin, hydraulic device, capable of developing
considerable forces in a simple and economic manner.
Initially designed by Eugene Freyssinet as a way of prestressing concrete,
to be used under specific circumstances, flat jacks were used for numerous
applications, in particular to apply or transmit forces while counterbalancing
the relevant strains.
The Freyssinet flat jack is a malleable steel capsule made up of two steel-welded
together, the connection being in the shape of a cylindral or toric rim.
Two adjutages tubes, one of which serves as a vent, allow fluid to be injected
under pressure which pushes aside the two faces of the jack while the strain
incurred modifies the shape of the rim.

Barrier Cables, which are used mainly
in parking garages to replace some of the other options barrier systems
available such as pre-cast or cast-in-place walls, galvanized pipe, turnbuckles,
... The barrier cable system seems to be enjoying popularity due to its
advantages. It is economical due to its high strength to weight ratio and
efficient to resists vehicle impact in the tensile rather than the bending
Earthquake Protection Devices, which
reduce the transmission of inertial forces, such as between a deck and
its piers during a seismic event.
These solutions offer numerous benefits, particularly with regard to installation
