For over 100 years, Sika has extensive experience and expertise in the repair and protection of concrete. With all of the necessary products and systems for the technically correct repair and protection of concrete, Sika delivers high performance solutions in accordance with the principles of European Standards EN 1504.
Long-term protection of a reinforced concrete building façade will not be achieved in most cases of deterioration by patch repair alone.
Patch repair will at best provide a “band-aid” with future repairs being required most probably in adjacent areas and at a higher future cost. It is therefore important that, in addition to the repair of visibly damaged areas, a protective system be applied to all areas as part of the future repair and maintenance strategy.
Types of Concrete Protection Products
Sika Offers All Types of Technology for Concrete Protection
For over 100 years, we have gained extensive experience and expertise in the repair and protection of concrete. With all of the necessary products and systems for technically correct concrete repair and protection, Sika delivers high performance solutions in accordance with principles and methods defined in local standards such as the European Standard EN 1504.
Hydrophobic impregnations are a special concrete protection solution applied to reduce water uptake behavior and prevent ingress of water-dissolved contaminants such as chlorides. The aesthetic appearance of the concrete surface will not be changed.
Reinforcement Corrosion Protection
Concrete protection also means protecting the embedded steel bars from corrosion. This can be done by applying a protective layer on the reinforcement, by using corrosion inhibitors or by cathodic protection.
Cathodic protection is one of the most effective means of protecting embedded steel bars in concrete and preventing corrosion. It is an electro-chemical technique to stop steel corrosion by galvanic anode or induced current.
Sika proposes a full range of anodes (galvanic and hybrid anode systems) to prevent the onset of incipient anode corrosion and to control corrosion in contaminated but sound concrete.
To provide a specific protection such as anti-carbonation or chemical resistance, a film-forming protective coat can be applied on the surface. Such protective coatings are available as rigid, plasto-elastic or elastic systems.
Sika also has permanent anti-graffiti and anti-fly poster coatings to protect concrete, wood, masonry and metal. They require no refreshing coat after the cleaning operation which can be repeated again and again.
Sometimes, concrete protection is not enough. Maybe you also need to restore the structural integrity or aesthetic appearance of the concrete, for example.
Sika has a full range of concrete repair products and systems, from repair mortars to smoothing mortars and pore fillers.
