Since concrete structures are often exposed to different aggressive environments, they require high
quality protection systems. Reinforced concrete structures are built to serve many generations to come.
However, concrete faces many threats of natural deterioration, damage and reinforcement corrosion.
Concrete Structures Have a Lot of Stress
Depending on their location and use, concrete structures are subjected to a wide range of exposure conditions – from normal atmospheric carbonation to the aggressive influences in polluted urban and industrial environments, plus marine atmosphere and liquid or gaseous chemicals, along with influencers that can damage or attack the concrete and embedded steel reinforcement.
Two Most Common Causes of Concrete Damage and Reinforcement
Corrosion
The two most universal causes of reinforcement corrosion and concrete damage are carbonation and chloride attack. The faster carbon dioxide or chlorides penetrate the concrete, the sooner the passive layer around the reinforcement bars is destroyed and the corrosion process is initiated. Understanding the root cause of steel corrosion determines the most effective repair and protection strategy. To ensure long-lasting durability, an appropriate maintenance strategy should be followed by owners and their construction management.
Buildmate 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, Buildmate delivers high performance solutions in accordance with principles and methods defined in local standards such as the European Standard EN 1504.
Hydrophobic Impregnations
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.
Buildmate 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.
Protective Coatings
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.
Buildmate 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.
Concrete Repair
Sometimes, concrete protection is not enough. Maybe you also need to restore the structural integrity or aesthetic appearance of the concrete, for example.
Buildmate has a full range of concrete repair products and systems, from repair mortars to smoothing mortars and pore fillers.
