Sika Offers All Types of Technology for Concrete Protection
With over 100 years of experience in concrete repair and protection, Sika has developed a complete range of products and systems to ensure technically correct and long-lasting solutions. To meet the specific requirements of each project, including exposure conditions, concrete quality, time constraints and accessibility, customers can choose among the following concrete protection solutions:
Active Corrosion Inhibitors
Using corrosion inhibitors may be a cost-effective solution to deal with corrosion of reinforcement in reinforced concrete structures. It depends on the exposures, environment, quality of concrete and amount of concrete cover.
Based on these factors, passive or active corrosion inhibitors are selected. Neither system alters the concrete appearance.
Passive Corrosion Inhibitors
Passive corrosion inhibitors, which includes hydrophobic impregnations, are a special concrete protection solution applied to reduce water uptake and prevent ingress of water-dissolved contaminants such as chlorides. They are easy and fast to apply without causing any change to the concrete appearance.
Protective Coatings
To provide specific protection such as anti-carbonation or chemical resistance, a film-forming protective coat could be applied on the surface. Such protective coatings are available as rigid, plasto-elastic or elastic systems.
Sika also has anti-graffiti and anti-fly poster coatings to protect concrete, wood, or masonry permanently from deterioration and vandalism.
Cathodic Protection
It is possible to electro-chemically reverse the naturally occurring corrosion current in concrete.
By applying a sacrificial metal (anode) or current, the cathodic protection solution ensures that the steel rebar stays passivated inside the concrete (cathodic mode). It is often the last and most effective way to refurbish critical infrastructure.

Our Concrete Repair Products and Systems
Repair and renovation of concrete buildings and infrastructure is an important process – it helps us to provide a sustainable approach to building – prolonging the life of a structure and preventing demolition and reconstruction. The choice of the appropriate rehabilitation strategy, based on the root cause of concrete failure, can also significantly improve the overall performance of a structure. Sika has a wide portfolio of products and systems to solve many concrete repair needs.
Corrosion protection and bonding primers are used for bonding concrete repair mortars to existing cementitious or steel substrates and providing additional corrosion protection to reinforcement steel, especially in areas of low concrete cover and in the presence of chlorides. Exposed reinforcement steel bars should be properly prepared and protected with anti-corrosion slurry to further enhance the repair process.
Advantages:
- Ready to mix, easy to apply
- Adjustable consistency
- Active corrosion inhibitors for added protection
- Can be sprayed or manually applied
Repair mortars are specifically designed for restoring or replacing the original profile and function of the damaged concrete. They help to repair concrete defects, improve appearance, restore structural integrity, increase durability and extend the structure’s longevity. Sika concrete repair mortars are suitable for restoration work, repair of spalling and damaged concrete in all types of structures including buildings, bridges, infrastructure and super-structures.
Advantages:
- Easy to mix and apply
- Pre-bagged for quality, just add water
- High mechanical properties
- Can be overcoated with Sika leveling mortars
- Can be sprayed or manually applied
- Pure cement-based, cementitious, polymer-modified and epoxy-based repair mortar materials available
When concrete needs to be coated or levelled, special mortars are necessary to fill the surface pores. Sika pore fillers and levelling mortars are thin layer renders designed to repair minor defects, such as repairing pores and honeycombed concrete.
Advantages:
- Easy to mix and apply
- Pre-bagged for quality, just add water
- Can be overcoated with Sika protection coatings
- Can be sprayed or manually applied
The most common causes of steel reinforcement corrosion in concrete are caused by carbonation or chloride ingress with water. Understanding the
root cause of steel corrosion determines the most effective repair and protection strategy.
Sika provides a full range of products to prevent further corrosion of steel reinforcement by properly protecting the concrete around it. Our corrosion management systems allow flexibility to select the most cost effective, suitable solutions for your project’s needs.

FAQ
Concrete can deteriorate due to reinforcement corrosion, freeze-thaw cycles, chemical exposure, structural movement or poor initial construction. Over time, these factors lead to cracking, spalling and surface degradation, reducing the structure’s strength and durability.
Signs like cracks, spalling, exposed reinforcement and surface discoloration indicate potential deterioration. A professional assessment can help determine the severity and appropriate repair method.
Sika provides a comprehensive range of concrete repair products, including repair mortars, corrosion protection solutions, structural strengthening systems and coatings to extend the lifespan of concrete structures.
To prevent further damage, use protective coatings, waterproofing solutions and corrosion inhibitors to safeguard concrete from moisture, chemicals and environmental stress. Regular inspections and maintenance also help extend the structure’s lifespan.

Yes. Sika offers three concrete repair and structural strengtheing CPDs:
- 'Concrete Repair - A Specifier’s Introduction to Concrete Repair (BS EN 1504)' which explains how reinforced concrete deteriorates, identifies causes of distress and gives guidance on selecting repair strategies.
- 'Car Park Structural Waterproofing & Protective Deck Treatments' which covers causes of concrete decay in car parks and exposed decks, and outlines waterproofing and protective treatment solutions to mitigate structural damage.
- The RIBA Approved 'Structural Strengthening with CFRP' that focuses on introducing CFRP strengthening systems, when to use them, how to prepare and install, plus stakeholder considerations for different structure types.
