Leading Specialist in Bridge Bearing Replacement

Where the condition of your existing bearings are concerned, no one is more capable, or experienced to advise you than Freyssinet, the UK’s leading bridge bearing manufacturer and specialist in bearing replacement. Freyssinet’s highly trained and experienced engineers, are available to come and complete site inspections throughout the whole of the United Kingdom and Ireland.

The services offered include identification of the bridge bearings, condition assessments, and advising on the practicalities of refurbishment, and/or bearing replacement. As part of the service, a comprehensive report is available, which would be photographically illustrated, and available in an electronic format as necessary. This allows the client to integrate our report into their own tender documentation and reports as required.



Freyssinet are the leading bearing manufacturer and experts in the fields of bearing replacement, you can be assured that your new bridge bearings and bridge bearing replacement works will be of the highest quality. Freyssinet offer the full range of bearing manufacture and bearing replacements, both elastomeric and mechanical, from their UK factory. The designs are to BS 5400, and the quality control of bearing manufacture and bearing replacement exceeds the requirements of BS EN ISO 9001.

The team of leading designers at Freyssinet are able include suitable modifications into original designs of bearing manufacture, so that later bearing replacement operations can be made easier.



The replacement of bridge bearings and other operations, such as bridge expansion joint replacement, require extremely specialised jacking and propping solutions to facilitate the work. Freyssinet can offer a wide range of appropriate techniques, no matter how demanding or challenging the situation is. Freyssinet are able to supply vertical jacks to prop up structures, and also horizontal jacks, to facilitate movement of structures.

1000 tonne capacity, hydraulic jacks are available from Freyssinet with locking collars and swivel heads. To complement these, Freyssinet can use their manufacturing expertise to add to the jack heads, elastomer and PTFE sliding surfaces. These surfaces give the jack heads the ability to accommodate a limited amount of horizontal, and vertical, structural movement.

For both permanent and temporary situations, Freyssinet also supply flat jacks up to a 1000 tonne capacity, which are able to be used in gaps of 50mm or even less. For temporary solutions, where removal of the jack will be required, the inflation would be with hydraulic oil. If the bearing is to be used in a permanent situation, such as structural lifting or bearing pre-loading, a cementitious grout may be used. Alternatively, at a later date, the grout can be transfused under load if the situation requires.



Control over the entire jacking operation, can be monitored either manually or electronically, offering extremely high levels of control. The jacks can be grouped together into complex circuits, where they can be operated either in groups, or individually as required.

If the client has specified a more conventional propping system for a temporary situation, Freyssinet’s in-house designers are well placed to accommodate this, offering big advantages in terms of cost, speed and access. Propping also eliminates the need for excavation and temporary foundations.



Whether you require experts for bearing testing, or a bearing manufacturer for a bridge bearing replacement project, Freyssinet’s are the ones you should turn to.

Concrete Repair and Enhancement

Despite its many undoubted qualities, unfortunately concrete does not last for ever. The state of any potential concrete structure repair needs to be professionally assessed, so that the appropriate steps can be taken to ensure the safety of the structure, as well as its sustained durability for the future.

Freyssinet are able to offer a complete solutions package for any concrete structure, no matter how large it may be, and no matter how much it may need in the way of concrete repairs. By using sustainable technologies, Freyssinet are able to do more, but with less materials and energy, which sets them apart from the competition. Freyssinet can offer a full range of integrated concrete enhancement solutions, including: concrete repair, concrete replacement, hydrodemolition, wall sawing and diamond coring.

Concrete repairs are perhaps the most effective way that Freyssinet can prolong the life of your structure. If the concrete shows signs of cracking, if it is spalled, if it has become honeycombed or damaged in any other way, a concrete repair, or in more extensive areas, concrete repairs, may be the answer.



Before any concrete repair work is completed, thorough testing needs to be carried out to assess the true nature of any damage or degradation. Freyssinet are able to offer a comprehensive range of tests to accurately identify and diagnose any problems, before advising on what structural concrete refurbishment is required. These tests can also identify any underlying causes that may need to be addressed, saving additional expense for concrete repairs later on.

Once the appropriate type of concrete repair is identified, a range of techniques are available, including: leak sealing, sprayed concrete, pressure resin injection, vacuum resin injection, or a combination of pressure and vacuum resin injection using epoxy, or patch and thin bond repairs using high quality, modified mortars.



If the concrete is in poor condition, it may be that a concrete repair is not a viable option. Concrete replacement may be necessary, and once again, Freyssinet have a range of solutions available.

Before any replacement can begin, defective concrete will need to be removed. As part of your total Freyssinet solution, removal can be performed by conventional breaking out, or by using hydrodemolition techniques, by Freyssinet’s own in-house team.



Hydrodemolition utilises high pressure water jets, and can be used in small and large areas alike. It can also be used for the removal of coatings, which will then provide an excellent surface for repair materials or new coatings to bond to. This technique reduces the risk of potential harm caused by vibrations, cleans existing steel re-enforcement whilst causing no damage, eliminates dust and debris, and can result in a more efficient programme.



The Freyssinet team have over twenty years of experience in a wide range of hydrodemolition applications. As well as being highly trained and experienced, you can rest assured that they conform with, and adhere to, all the latest health and safety and quality standards of the industry.

Once the old concrete has been removed, Freyssinet will replace this with high performance concretes and mortars.



Concrete repairs and replacement are only part of a wide range of complimentary services offered by Freyssinet. Whether your project involves concrete bridge repair, concrete building repair, or any other kind of concrete structure repair, Freyssinet can offer a holistic package of products and services. Diagnosis, prevention and cure, are all part of the service offered by a company with the reputation, credentials and experience that have secured them landmark projects for the Highways Agency, and many others.

Structural Strengthening Experts

When you have a concrete structure that needs modification to prolong its lifespan, or a change of use needs to be accommodated, then strengthening is a possibility that should to be considered.

Freyssinet are in a position to offer clients a wide range of options when it comes to strengthening. Some of the potential applications for the various strengthening techniques include: increasing the floor slab load that is allowed, strengthening of the bridge deck, adding strengthening to new openings, and strengthening columns.

External post tensioning is appropriate when dealing with bridge decks in particular. Along with everything else Freyssinet have to offer is, a complete design and install post tensioning service for any of your existing structures. No matter how big the project may be Freyssinet can meet even the most demanding post tensioning applications. If the bridge structure is a large span box girder, Freyssinet can fit additional post tensioning inside the structure itself. External post tensioning can also be used to upgrade circular storage tanks, or to make them watertight. Tendons fitted to the outside of smaller span structures, are also something offered by Freyssinet.



In existing areas that have a high stress concentration or that may be subjected to bursting forces, pre-stress may need to be introduced. Freyssinet can meet these needs with their own Freyssibar pre-stressing system. This is a comprehensive range of fully threaded, high strength bars that are complimented by extension, coupling and anchoring systems. If you have an over-stressed area of an existing structure, this solution can be an effective remedial action. Freyssibars can also be an excellent option, if you are looking to increase the load carrying capacity of your existing structure with high tensile bars.

If under strength floor slabs or beams are the problem, you may want to consider plate bonding. This is a process where Freyssinet can take appropriately sized steel plates, then bolt them or bond them, with an epoxy adhesive to a structure’s tension zone. By applying this process to the specific area, the load carrying capacity can be increased as required, up to a certain degree.



Another alternative solution offered by Freyssinet is the use of a carbon fibre product called TFC. This reinforced polymer carbon fibre product is manufactured in house by Freyssinet, and can be an outstanding option in the right circumstances. TFC can be particularly useful if the area you need to reinforce has a complex profile, or if clearance height is an issue, such as in a multi-storey car park for example. Other advantages of TFC are that it adds no extra weight to the structure, it is suitable for use in a wide range of temperatures, and it is resistant to UV, fire and shocks.



The correct type of strengthening application is dictated by the structure, its use, its design, and the amount of desired load carrying increase to be achieved. All of these factors require careful consideration, which is why Freyssinet offer a complete design and build service for its clients. Their in-house teams can assist in deciding which is the most appropriate technical and economical solution for your strengthening requirements.

Structural Enhancement Specialists

Concrete deterioration is mostly caused by the combination of reinforcement corrosion which has been made worse by a surrounding concrete suffering from a reduction of alkalinity. The principle instigators of this form of deterioration can be carbonation and chloride attack. Carbonation can be caused by carbon dioxide that exists in the atmosphere, whilst chloride attacks are most likely the result of marine aggregates, de-icing salts or seawater. To minimise the effects of these elements, some form of concrete corrosion prevention is required.



To address the challenge of concrete corrosion prevention, there are several structural enhancement techniques to look at. These techniques include cathodic protection, coatings, grout injection, resins and wax injection. Freyssinet have been using these techniques for over thirty years, so you know that you are in good hands.

Cathodic protection is a concrete corrosion prevention technique that can be used where patch repairs are likely to be unsuccessful. Situations where cathodic protection may be the best form of concrete corrosion prevention are where there are sufficient amounts of chlorides in untreated areas of adjacent and untreated concrete. Cathodic protection may also be the best course of action where carbonation has managed to get behind the reinforcement layer.



The process of cathodic protection is achieved by passing a small amount of electric current through the reinforcement layer and offers several advantages over other concrete corrosion prevention techniques that can be used. Being a continuous process, it not only stops the existing corrosion; but also prevents further corrosion attacking the structure at a later date. There is also no need for any reapplication, it can be used on very badly damaged concrete, protects against both carbonation and chloride and can be adjusted and controlled through constant monitoring. Furthermore, it is a more economical alternative form of concrete corrosion prevention than concrete replacement. Cathodic protection is especially well suited to marine and motorway structures, which are highly susceptible to corrosion.

To prevent chemical attack whilst providing waterproofing, with limited maintenance costs and a long life expectancy; coating treatments are the answer. Freyssinet can provide clients with an extensive and full range of coatings to inhibit corrosion, provide anti-carbonation, waterproof and resist chemicals.



Void filling solutions can be applied using the injection of resins and grouts in both structural and non-structural applications. The latest vacuum assisted grouting technology, resin and polyester epoxy is used along with both high and low pressure injection equipment to deal with fine cracks within reinforced concrete structures. A wide range of different injection techniques are employed by Freyssinet’s teams of highly trained specialists. Whatever the problem, you can be assured that they have the expertise, experience and equipment to do the job.



For the full range of treatment work, from post-tensioning to ground anchors, more often now Freyssinet find it better to use wax injection, rather than more traditional grouts. The two major benefits for wax are its properties as a modern semi-solid bonding substance make it, more corrosion resistant, and a more flexible bonding agent to work with than traditional grouts. No matter how big the job, Freyssinet can provide the equipment needed, whether it’s a project needing 2 litre ‘top hat’ caps, or a 2000 litre application.

Bridge Rehabilitation Techniques – Bearing Inspection, Testing Service and Bearing Replacement

The infrastructure of modern bridges is composed of reinforced or pre-stressed concrete and steel structures. Over time, the constituent materials are affected by fatigue and general wear and tear from vehicular traffic. Wear and tear may also be aggravated by increased wheel loads and exposure to external factors such as extreme climatic conditions. Expansion/contraction and load transfer components like expansion joints and bridge bearings will eventually need rehabilitation or replacement.

Freyssinet Complete Further Works Under Highways Agency Framework

Freyssinet Limited are continuing to work successfully in collaboration with other specialist contractors under the Highways Agency Area 9 & 10, Construction Management Framework.

The CMF is a collaborative approach to maintaining £75billion worth of assets for HA in these areas over the next 4 years. It consists of a number of different contractors from different specialist areas who work together to deliver network improvement and maintenance schemes on the all purpose trunk road and motorways in Highways Agency Area 9 and 10, which covers much of the West Midlands and North West.

Bromford Viaduct is one of a number of viaducts forming the Midland Link Motorway Viaducts (MLMVs). There are 21km of elevated motorway comprising 1200 no. cross beams and 3600 no. columns, constructed between 1969 and 1972.



During the mid 1980s corrosion started to occur due to de-icing salts leaking through deck expansion joints onto cross beams. Initial preventative measures, such as placing gutters beneath the expansion joints, were implemented during the mid – late 1980s and repair works in 1990. Concrete repair and cathodic protection schemes have been on-going to the present day based on calculated intervention dates for each cross beam. Repair Contract 153 (R153) commenced in January 2011 and comprises of 8 no. cross beams. With Amey acting as Principle Contractor, Freyssinet Limited was appointed as a specialist contractor within the Highways Agency Area 9 &10 CMF.

The scope of works involved removing sections of concrete to be repaired by saw cutting and hydrodemolition, undertaken by Freyssinet’s own in-house hydrodemolition team. Repairs were carried out as necessary to reinforcement steel, and the areas re-instated using flowable concrete, with some beams repaired under a supported condition.



Cathodic protection to 2 no. beams involved the installation of Galvanic (Sacrificial) anodes, whilst the remaining 6 no. beams had an Impressed Current Cathodic Protection (ICCP) system installed. The ICCP was designed as a 3 no. zone system; zone 1 to the shear walls being a ribbon mesh primary anode with a spray applied conductive overlay, zone 2 to the beam top and upper section of the beam sides being a ribbon mesh anode with non-conductive repair mortar overlay, and zone 3 to the lower section of beam sides, beam soffit and top of columns being a similar system as zone 2.

Technical issues which prevented supporting steel work being erected to underside of 2 no. cross beams threatened to cause delays to the programmed works, and Freyssinet’s installation of the CP system in particular. Successful cooperation between all parties resolved this situation, and the works were re-sequenced to enable Freyssinet to begin installation works ahead of programme by utilising concrete curing periods where there was no other activity taking place in the work area.

The designers also re-sequenced concrete repair works so that as far as practical, whichever half of each beam needing least repair was concentrated on in initial repair stages and would be complete in advance of the other half of beam, freeing up nearly 50% of CP installation work to be done before completion of concrete repairs. This method was applied to all beams where programmed work extended beyond Christmas 2011.

Utilising Freyssinet’s own in-house hydrodemolition team contributed to the success of the new programme. Where concrete surface hydro-prep was required for overlay material, the team was able to mobilise immediately, taking advantage of short durations of concrete curing time, all the time pulling back the programme.

The cathodic protection on R153 was commissioned with performance verification taking place 45 days after ‘switch-on’ in early December 2011.

Successful cooperation between all parties resulted in the programme being pulled back to mid December 2011, offering the client savings in terms of both time and money.

Concrete Bridge and Highway Structure Repairs, Strengthening and Hydro-Demolition

Freyssinet Limited is an expert provider of concrete bridge repairs and structural concrete refurbishment. Owing to their experience and excellent track-record in bridge and highway structure repair and all aspects of concrete repair, the Highways Agency and numerous Local Authorities are regular clients.

Coatings
Pore-lining impregnants are often applied to bridges exposed to chlorides before they are opened to traffic. However, when the level of chloride reaches reinforcement depth the coating will not stop corrosion and permanent concrete bridge repairs will need to be done.

Patch Repairs
Patch concrete repairs have historically been the conventional method of concrete bridge repair. However, this method requires the removal of undamaged (but chloride-contaminated) concrete which is otherwise in sound condition. In addition, patch repairs inevitably increase the corrosion in surrounding areas of concrete.

Electro-chemical Cathodic Protection (CP) – Concrete Corrosion Prevention
The Cathodic Protection method does not require the removal and replacement of chloride-contaminated, but otherwise sound, concrete. This significantly cuts concrete quantities and reduces on-site working time, minimising the cost of concrete repairs to bridges and highway structures.

Hydro-demolition for Bridge and Highway Structure Repair
As part of its forward-thinking approach to structural concrete refurbishment, Freyssinet offers clients the advantages of hydro-demolition concrete removal by their own in-house teams.

Efficient Concrete Removal Hydro-demolition is a high-pressure, water-jetting technique for the efficient removal of both damaged and sound concrete. It can be used with equal effectiveness on small areas of localised damage, for extensive concrete repairs preparation and for removing existing concrete coatings. Hydro-demolition is an excellent preparation for concrete repairs, leaving a perfect bonding surface for new coatings and all types of concrete repair material.

Advantages of Hydro-demolition for Bridge and Highway Structure Repair Hydro-demolition offers a number of important advantages in comparison to conventional concrete removal methods used in concrete bridge repairs and other concrete structures e.g. jackhammer removal.
• Eliminates all dust and debris
• Cleans existing reinforcing steel
• More efficient process reducing on-site programme
• No damage to reinforcing steel
• No hand-arm vibration injuries
• No vibrations ensures no cracking or micro fractures in the structure
• Surfaces are prepared perfectly to key-in new concrete and receive mesh overlay

Experienced Team The Freyssinet Limited hydro-demolition team is highly trained with more than 20 years of solid experience in hydro-demolition applications including concrete bridge repairs and all types of concrete structures.

Health, Safety and Quality The hydro-demolition team wears the latest TST PPE, including 2000 bar-rated bib and brace, TST safety gaiters to cover safety wellington boots and TST waistcoats.
