LIVIZA concrete cover blocks are small concrete elements used in reinforced concrete structures to maintain the prescribed distance between the reinforcing bars (rebars) and the outer surface of the concrete. These blocks help to ensure that the reinforcement is properly covered with concrete, which is critical to the durability and structural integrity of the concrete elements.

During concreting, the LIVIZA cover blocks ensure that the reinforcement remains in the desired position and that the specified concrete cover is maintained evenly throughout the structure. Improper concrete cover can lead to various problems, such as reduced structural strength, increased risk of corrosion and potential structural failures. Therefore, the correct placement and use of concrete cover blocks is essential in reinforced concrete construction.
