Selection of the appropriate method for concrete restoration will depend on several parameters, such as the extent of damage, reinforcement density, accessibility, quality control issues, and public health issues. Includes these methods according to the EN 1504-9 standard. Principle 3. Concrete restoration: Method 3.1 Application of mortar by hand Method 3.2 Filling with concrete Method 3.3 Projection of mortar or concrete Manual application mortars Traditionally, localized repair of damage and defects in concrete is carried out with manually applied mortars (method 3.1).
It is used for limited damage. There are pre-dosed manual application mortars for general repairs and also for more specific uses. These include lightweight mortars in overhead applications (for example, on roofs) and chemically resistant materials for protection against aggressive gases and chemicals.

Source: ANFAPA Filling with concrete or mortar Repairs by pouring or filling are used when large areas and sections of concrete need to be regenerated (method 3.2). This method is very useful for repairing support sections in complex structures such as headlands, piers and pillar sections that often present access and reinforcement density problems.
The most important criterion for a successful application of this type of products is the fluidity and ability to fill the gaps around the reinforcement. Additionally, they are often poured in thick sections without creating shrinkage cracking problems. This ensures that the desired volumes can be filled completely, despite access restrictions and application points. Finally, they must also harden and provide a suitable, level and crack-free final surface .

It is useful for large volumes , to provide additional coating to concrete, or in hard-to-reach areas for pouring or hand application.
