Application fields
Freyssinet anchoring systems are used to hold, restrain and support buildings and civil engineering structures, either permanently or temporarily.
Anchoring products are engineered systems that stabilize grounds and/or fix a structure to the ground, enabling load transfer into an appropriate stratum.
The anchors ensure the stability of the soil and allow for large and deep excavations. They are often temporary, as the long-term stability of the ground will be ensured by the structure built in the excavation (car parks, basements, etc.).
The anchor is the essential element that transmit forces from a retaining wall to the ground and ensures the overall stability.
Vertical anchors are generally pre-stressed and improve the stability of dams, while reducing water ingress along the contact line with the rock.
Ground anchors are generally used to improve the stability of an existing quay wall.
For new construction, port tie rods are used to transfer the forces to rear piles or sheet piling.
Anchors ensure the stability of galleries by balancing the forces of the ground. This technique applies to mines and tunnels.
Vertical anchors provide an effective link between the foundation and the ground, while limiting the effects of fatigue when pre-stressed. The anchors can be used for towers, radio masts, wind turbines, etc.
Anchors allow structures to be built on low bearing capacity or unstable ground. The vertical loads of the structure are transmitted to the deeper, stable areas.
Anchors are used to hold structures in place that are subject to high water uplift pressure and therefore allow structures to be built in underwater areas by compensating for Archimedes’ principle.
Anchoring a cable anchor block to the ground by means of pre-stressed ground anchors makes it possible to limit or cancel the movements, and therefore the fatigue effect.

An end-to-end service
Specification and design services
As part of our integrated approach, we provide the customized design of the required anchors to suit your project needs.
Production and quality control
As with all products designed and manufactured by Freyssinet, components and finished products are subject to strict controls based on the most stringent international standards. Freyssinet manages production and ensures quality control within its industrial subsidiary FPC (Freyssinet Products Company) based in France, which is ISO 9001 (quality), 14001 (environment), 45001 (safety and health) certified.
Installation and corrosion protection
Local teams of specialist technicians work on-site to carry out all the operations associated with installing anchors, in accordance with the applicable standard. They are particularly trained to master creep movement and carry out drilling, injection and tensioning operations and all tests needed (tensile, compression, conformity, inspection, etc).
Inspection and maintenance
Our geotechnical systems are designed for long life with minimal maintenance. Regular inspection of their condition and proper preventive maintenance will further extend their life. Dedicated standard monitoring equipment is available. Please contact us for recommendations and services in this area.
Freyssinet offers a wide range of systems
These are multi-strand ground anchors, based on Freyssinet post-tensioning systems (ETA 06-0226, CE marking) and designed as post-tensioning solutions for geotechnics.
Temporary, semi-permanent and permanent anchors are available, offering a different corrosion protection class (EN 1537).
Standard range up to 13 strands, larger anchors on request.
Used for excavations, pylons, buildings and bridges
Made of GFRP (Glass Fiber Reinforced Polymer) instead of steel, this innovative system is used to stabilize excavations: to allow subsequent drilling or excavation without the risk of obstruction by steel left in the ground after initial work, to prevent the spread of stray currents, or for tax reasons. There is no need to remove the tendons after use, Cuttable Ground Anchors can be easily cut or destroyed by any drilling or excavation equipment.
Their main components are derived from the Freyssinet prestressing bar system (ETA-09/0169). The corrosion protection for temporary or permanent use and the injection system are specifically adapted to comply with international standards for ground anchors and tailored to project specifications.
Used for excavations, pylons, dams, buildings and bridges
The bar Freyssi500-E is a hot laminated bar made of reinforcing bar steel grade (500/550). It has ribs that form a thread along its entire length, allowing accessories (couplers and nuts) to be screwed in at any point. With its large range of diameters from 16 to 75 mm, it is used for all types of anchors: ground anchors, soil nails & rock bolts, micropiles, tie rods. The Freyssi500-E is designed with a left-hand thread.
Used for excavations, dams, pylons, buildings and bridges
The bar Freyssi670-E is a hot laminated bar made of a specific steel grade (670/800). It has ribs that form a thread along its entire length, allowing accessories (couplers and nuts) to be screwed in at any point. With its large range of diameters from 18 to 75 mm, it is used for all types of anchors: ground anchors, soil nails & rock bolts, micropiles, tie rods. The Freyssi670-E is designed with a right-hand thread.
Used for excavations, dams, pylons, buildings and bridges
The system is used for anchors installed in loose soil or where the borehole may collapse. It allows drilling, installation of the bar and grouting in a single operation, which avoids the use of a casing. The system consists of:Fully threaded hollow bars from R32 to T76 (higher diameters on request) Couplers, Nuts and anchor plates, Drill bits
Used for excavations, dams, pylons, buildings and bridges
