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 leveling 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.
Cosmetic repairs address surface damage, such as cracks and spalling, without affecting structural integrity. Structural repairs involve damage that compromises load-bearing capacity, requiring specialised repair mortars, reinforcement techniques or injection solutions.
Yes, Sika offers the CPD Concrete Repair – A Specifier’s Introduction to Concrete Repair (BS EN 1504), which is specifically designed for structural engineers. This CPD provides valuable insight into the key factors contributing to the deterioration of reinforced concrete, explores typical causes of distress and outlines appropriate repair and remediation strategies. It also covers modern material technologies including repair mortars, corrosion inhibitors and protective coatings. Book this CPD here.
