Throughout history, bridges have always been important, valuable structures in their own right. By their very nature, bridges are built in a variety of areas where the topography, ground conditions, or other existing structures and developments are unsuitable for conventional pathways, roads or railway construction. Therefore, bridges are found in the most challenging, exposed environments.

Modern bridges built using reinforced concrete or steel often require a service lifespan of more than 100 years. Recent surveys in Europe and North America have shown that the majority  of existing bridges already exhibit significant degrees of degradation. Many of them are therefore in need of substantial and often urgent repair and refurbishment.

Bridge Exposures

Bridge Icon  - Sika Solution
Water Ingress

Water can penetrate naturally through the capillary pore structures of reinforced concrete. In areas of carbonated concrete, or where there is a high chloride content on the surface of the steel reinforcing bars, reinforcement corrosion, cracks or spalling can occur on the surface.

Bridge Icon  - Sika Solution
Dynamic and Static Load

Overloading due to increasing traffic loads, inadequate design, damage to the structure, stress/fatigue failure, earthquake effects, or any other mechanical impact such as vehicle impact, can all exceed or reduce the load capacity of the structure.

Bridge Icon  - Sika Solution
Temperature Variation

By their nature and locations, bridges are subjected to a wide variation of temperatures between day and night/winter and summer conditions, or between different sides or surfaces of the structure. These frequent cycles result in thermal stresses and movement in the concrete structure that can also result in cracks.

Carbon Dioxide

Carbon Dioxide (CO²) reacts with the Calcium Hydroxide (Ca(OH)²) in the pore liquid of the cement matrix of concrete structures and deposits as calcium carbonate (CaCO³). This process known as carbonation reduces the protection of embedded steel reinforcement, when the process reaches the reinforcement bars.

Bridge Icon  - Sika Solution
Chlorides Ingress

Chlorides come from de-icing salts used in winter, or from saltwater in marine environments. They can penetrate the concrete structure and once they reach the reinforcement bars, they can locally destroy the passivation film causing fast pitting corrosion.

Bridge Icon  - Sika Solution
Freeze / Thaw Action

The freeze-thaw process creates stresses in the concrete matrix due to the expansion of free water in the capillary pores during freezing conditions; this can result in the scaling of the surface of poor quality concrete. This action is also greatly accelerated by the presence of chlorides in the water.

Bridge Icon  - Sika Solution
Surface Erosion / Abrasion

Concrete elements submerged in water such as the bridge piers or columns are continuously exposed to erosion and abrasion of their surfaces. Damage occurs from the action of fast-flowing water, and the particles of sand or other solid materials in the water.

Bridge Icon  - Sika Solution
Fire Damage

Fire due to traffic accidents, for example, can result in a reduction of the structural integrity of any of the concrete elements including the columns, decks or precast segments, etc.

Solutions for Bridges and Highways

1. Concrete Technology

Concrete structures such as bridges can be exposed to a broad range of forces and strains, starting internally with mechanical stresses resulting from the construction type and extending to various external attacks. Enormous stress on the concrete include such factors as extreme hot or cold temperature conditions and fluctuations, aggressive water or chemicals, continually rolling, abrading or pulsating strains on surfaces, or even in extreme cases the impact of fire. Therefore, a highly durable concrete is necessary for the construction or repair of a bridge.

The development and production of innovative concrete mix designs using special admixtures has been a core Sika business since 1910. Our technology and high-quality products have been continuously developed during this century of experience. Sika provides the most complete range of admixture technologies and products for the efficient replacement of highly durable concrete.

3. Structural Strengthening

If the existing steel reinforcement is reduced in capacity due to corrosion, if the traffic loads are increased (i.e. permissible axle weights), or if the structural design or seismic resistance needs improvement, then reinforced concrete bridges have to be strengthened.

Sika has been involved in structural strengthening since the development of the technology in the 1960’s using bonded steel plates. Since 1991, Sika has also been a pioneer with the development of carbon fiber reinforced polymer (CFRP) based structural strengthening systems. As a leader in strengthening all types of reinforced concrete structures, Sika provides a full range of fully tested and approved strengthening systems.

4. Waterproofing

Bridges are an essential part of modern infrastructure and are often subject to the harshest weather that climates have to offer. In order to maintain the durability over its design life, special attention should be given to the waterproofing and protection of exposed elements and critical areas such as the bridge deck itself, to prevent serious damage to the concrete and structural reinforcement.

Bridge Deck Protection

Due to constant movement, the deck waterproofing system must be able to accommodate dynamic traffic loads and bridge cracks whilst still maintaining a strong bond with both the substrate and asphalt road surface. Bonding failure can lead to loose or rucked road surfaces allowing water, chlorides and chemicals to attack the structure, reducing the design life.

New technology with Sikalastic®-851 waterproofing membrane, liquid applied membrane based on polyurethane or polyurea, together with innovative Sikalastic®-827 pellets-system for high bond and shear strength (see "Bonding Asphalt Overlays") make a reliable bridge deck protection system.

SikaBit® bituminous membranes have high resistance to puncture, durability and heat compatibility, making it suitable for systems subjected to traffic. It is certified according to EN 14695 - reinforced bitumen membranes for waterproofing concrete bridge structures and other concrete surfaces subject to traffic.

Bonding Asphalt Overlays

New innovative Sikalastic®-827 pellets bond asphalt overlays to Sika waterproofing systems by expanding and melting, forming a mechanical and chemical bond at the interface. This dramatically increases both shear and tensile bond strengths, thus increasing safety to heavy traffic braking and long term durability.

5. Joint Sealing

Bridges are complex and demanding structures. There are many joints that need waterproofing, from simple saw cut contraction joints to exposed movement and connection joints. These joints are exposed to thermal movement, constant vibrations, extreme weathering, mechanical impact from the traffic and chemical impact from spillage or de-icing.

The sealants must reliably prevent water from entering the structure and causing decay of concrete and steel components through corrosion. Durable waterproofing has a significant impact on the life expectancy of the bridge.

Elastic Joint Sealing

High performance watertight joint sealing systems for use on bridge decks, parapets, and other elements:

For facade and parapet joint waterproofing: Sikadur® Combiflex® SG system

For bridge deck and deck waterproofing edge terminations: Sika® Dilatec® B, R and E edge systems

For facade joint waterproofing: Sikaflex® joint sealants

Joint Sealing for Connection Joints and Movement Joints

The rapid completion of construction and refurbishment works has been a driver of innovation since many years. Examples are reduced curing times of concrete and application over a wider temperature range, application on humid substrates or fast curing of sealants, adhesives and coatings.

The fast curing of a sealant can be achieved by adding a booster. Sikaflex®-406 KC is a single component sealant that is accelerated with a booster, Sikaflex®-406 KC Booster. The Sikaflex®-406 KC system unites the advantages of a one- and two-component systems.

6. Concrete Protection

To improve the performance and durability of reinforced concrete surfaces on bridge structures, additional protection systems are frequently required, particularly in refurbishment situations. Typical concrete protection systems for bridges can be classified as hydrophobic impregnations, sealing impregnations, surface coatings, or corrosion inhibitors. These are designed for use in different situations or collectively in alternative combinations, to greatly reduce damage to the concrete surfaces, to stop or reduce the rate of steel reinforcement corrosion and prevent significant structural damage.

Sika provides a wide range of tested and well proven concrete protection systems based on different technologies including hydrophobic or sealing impregnations, rigid and elastic surface coatings, galvanic anodes, and surface applied corrosion inhibitors.

7. Grouting and Fixing

Remedial works on concrete bridge structures often include the requirement for void filling, fixing and sealing or bedding and grouting with free-flowing materials. Typical examples are concrete repairs using formwork, high precision grouting under bridge bearing plates, or for cable duct grouting. Additionally flowable resin and cement grouts are used to fix manholes or other steel frames and equipment, where rapid hardening materials are usually required to reduce closure times.

Sika provides a wide range of tested and well proven grouts and fixing materials based on all of the different technologies available including cement, epoxy, polyurethane and PMMA. For many decades, Sika has also provided special products for high precision applications such as bearing plates, rail tracks and duct sealing.

8. Structural Bonding

Structural adhesives are used for many bonding applications in new construction and refurbishment. The bond must allow the transfer of high loads without deformation and creep. The main function of structural adhesives is in the bonding of similar or dissimilar materials together (i.e. concrete to steel, steel to composites etc). Dependent on their design, structural adhesives can not only bond the elements together, but they can also fulfil additional functions such as waterproofing, sealing, concrete protection or even vibration dampening.

Sika has been a pioneer in the use of resin adhesives for structural bonding of precast concrete elements since the 1960’s. Sika’s epoxy adhesives have now been used to bond segmental bridge structures all around the world. This extensive experience has allowed the development of a wide range of additional structural bonding products and systems for unique applications. In the 1990’s Sika also introduced a complete range of cartridge applied resin anchoring adhesives for many different applications.

Segmental Bridge Adhesive (SBA)

Segmental bridges are built in short sections (called segments) one piece at a time, whereby traditional methods build a bridge in very large sections. Segmental bridges are made of precast concrete, which is manufactured at another location and then transported to the final location for placement within the complete structure. They are very economical for long spans (over 100 meters), especially when access to the construction site is restricted, and also allow for special design features to enhance the beauty of the structure.

Sika offers Sikadur-31 SBA: Range of thixotropic, structural two-part adhesive specially formulated for segmental bridge construction; available in different grades to suit different applications and environmental conditions. All grades present advantages including: meets and/or exceeds internal and national standards (FIP, BS, AASHTO, ASTM, etc.), high strength, high modulus of elasticity, no primer required and more.

9. Wooden or Masonry Bridge Repair

Generally, wooden or masonry bridges are old structures and may suffer from decays over the ages, which is most often due to a lack of deck waterproofing or other structural component failure. On some occasions, the design load no longer complies with new traffic regulations, and structural strengthening is required. An invisible solution is often required in order to maintain the appearance of old, historical or iconic structures.

Sika offers expertise in the rehabilitation of masonry or wooden bridges. As a specialist in waterproofing, masonry protection, and structural strengthening, Sika offers a full range of systems to prevent water ingress and to increase the structural capacity of these old structures.
