These advantages include the short time needed to achieve high strength, the ability to hold water that helps concrete and cement mortars, the non-separation of aggregate and grout water from each other, and the lack of significant shrinkage. These materials have the ability to flow in a normal state and have high mechanical and chemical resistance, as well as the complete filling of the grouting place, high compressive strength, and psychological properties compared to other construction materials are considered among the advantages of this material. High adhesion is also one of the features that make grout a safe and efficient option in the construction industry and provides high resistance to environmental factors and continuous use

Types of grout

Grouts are produced in different types, some of which are

Polymeric grout: Polymeric grout, with high adhesion to concrete, is used in the construction and repair of concrete structures that need renovation. Due to their adhesive properties, these materials can repair old polymer concretes and even concretes with a worn cement base and increase their useful life. The reduced permeability characteristic of polymer grouts allows engineers to take advantage of it in structures that come into contact with liquids and chemicals, such as swimming pools or sewers. Also, the corrosion resistance of these grouts, in corrosive structures such as the chemical industry, is presented as an effective protection solution for concrete structures. As a result, polymer grouts as advanced structural materials are very useful in the improvement and productivity of concrete structures and in renovation or repair projects Cement grout: It is very common for installing ceramic tiles in construction projects. As a functional mortar, this material is also used in many activities related to home maintenance and repairs. To increase the hardness and strength of this cement grout, Portland cement is used as a hardener. This type of cement grout is usually sold as a dry powder in the market and is ready to use after mixing with a certain amount of water. Cement foundation grouting is a vital process in the construction of buildings that requires strict procedures and safety standards. Before starting the grouting, it is necessary to ensure the proper placement of the supports and the base plates. The surface of the base plates must be smooth and level, and the concrete under them must be at least 7 days old. Measures have also been announced to prepare the surfaces before grouting. The roughness and health of the concrete surfaces should be ensured and a distance of at least 1 cm should be maintained between the concrete and the surface under the base plate, and the surfaces should be cleaned of pollution and dust and then saturated with drinking water. The use of impervious molds higher than the surface of the base plate prevents cracking and rapid loss of mortar water. In cases of high density, it is recommended to create shaped funnels in the corners of the mold. Ensuring adequate clearance is essential to prevent air from trapping under the supports. The suitable temperature for this process is between +5 and +30 degrees Celsius. Keeping the mortar in wet conditions for 7 days is also necessary in order to achieve the desired resistance. These measures help to ensure the optimal performance of grouting and cement base Two-component or three-component epoxy grout: This material contains three main components, namely epoxy resin, polyamine hardener and silica powder. Due to the combination of these components, epoxy grouts show significant resistance to chemical attacks and dynamic loads. To use this grout, it is necessary to combine all three components together. These grouts have their special features due to their high strength against vibrations, adhesion to mineral and steel surfaces, and the speed of hardening of the structure according to the ambient temperature. The main applications of this type of grout include use in industrial factories, such as generator factories, manufacturing of motor machinery and wheels, in addition, the use of these grouts for the implementation of prefabricated concrete and steel columns, around piping channels, connections, foundations and in order to increase resistance. The structure in buildings, bridges and other structures is one of the common applications of these grouts Expandable ready-made grout: this ready-made cement-based mortar, with high resistance and controlled expansion, due to the special structure and granularity of its components, is very suitable for filling the empty space under base plates, implementing foundations of heavy machinery, steel substructures and stabilizing prefabricated columns. . This ready-to-expand grout, with high initial strength and fast loading capability, is suitable for immediate use of the structure. This material is also used as an expanding grout to fill the space around reinforcements, cracks and pits. High compressive strength and usable under columns and industrial base plates, both in the short term and in the long term, make this material an ideal option for use in construction projects.

Grout implementation steps

Grout or dry mortar and liquid grout are two common methods in the implementation of construction projects, each of which has its own advantages and uses

Dry grout or mortar: In this method, grout or mortar materials are moved to the desired location by compression force. This process requires the use of special equipment such as compression and pressing devices. This method is mainly used in cases where it is very difficult to access the place or create holes. Among the advantages of this method, we can mention the ease of implementation and efficiency in limited conditions Liquid grout: In this method, places and holes that are difficult or impossible to access are filled through the use of liquid grout. These grouts move by themselves due to their fluid state. This method is mainly used in situations where limited space, underground cavities or complex structures cause problems. This method benefits from high flexibility and the ability to penetrate into difficult places Each of these methods may be chosen depending on the environmental conditions and project needs. Now that you have chosen your grout, the steps of its implementation should be such that before the implementation of the grout, the desired surfaces are carefully cleaned of any pollution and harmful particles. Use a suitable brush at this stage. After completing these steps, prepare the product according to the instructions on the grout packaging, and the final thickness of the grout should be proportional according to the recommendations specified on the product packaging. At the time of execution, spread the grout simultaneously and continuously on the surfaces and note that it starts from the side that has the least distance to the desired surface. After finishing the application, pour water on the surfaces to get the best result

Disadvantages of using grout in retrofitting

Disadvantages of using grout in strengthening:

It is true that grout has many advantages for reinforcing concrete structures, but its use also has disadvantages that must be considered before use:

1. Contraction:

One of the biggest disadvantages of grout is its shrinkage after drying. This shrinkage can lead to cracks in the concrete or separation of the grout from the surface. To reduce this problem, special additives or non-shrink grouts can be used.

2. Sensitivity to humidity:

Cement grouts are sensitive to moisture and can deteriorate when exposed to water or high humidity. This makes them unsuitable for use in wet or underground environments.

3. Difficulty of implementation:

Some types of grout, especially epoxy grouts, can be difficult to work with and require skill and experience. Mixing and pouring epoxy grout must be done carefully to avoid air bubbles.

4. Cost:

Epoxy grouts and other high quality grouts can be significantly more expensive than regular cement grouts.

5. Environmental issues:

Some types of grout, especially epoxy grouts, can contain harmful chemicals that are dangerous to human health and the environment.

6. Restrictions on application:

Grouts are not suitable for all types of repairs and retrofitting. For example, they may not be suitable for filling large gaps or cavities.


Grout injection machine, pump and accessories, drill and related tools, grout mixing tools and flexible hoses for grout injection.
Adding grout to concrete can help increase the adhesion between concrete and steel. This advantage is very important, because in many construction structures, such as bridges, tall buildings, ports, etc., steel is used as a basic material for building structures. Therefore, increasing the adhesion between concrete and steel saves the building from destruction.
Due to the property of expansion, cement grouts create a very strong connection that does not have any contraction. The tensile and bending resistance of cement grouts is extremely high and can withstand sudden earthquakes. The compressive strength of cement grouts is very high along with their tensile strength. Cement grout does not rust or corrode in any way, because no iron aggregate is used in it.
