Grouting is a method often used to repair damage in building structures. It's important to note that various damages commonly occur in construction, such as hairline cracks or weathering.
If the damage is not on the surface of the construction, grouting can be a solution to fix it. Besides repairing damage, grouting also offers other benefits. For those unfamiliar with grouting, read the following information in this article.
What Is Grouting?
Grouting is a method used to fill gaps, voids, or cracks in concrete structures. Generally, the grout mixture consists of cement, water, sand, and certain chemicals. The process involves injecting the mixture into the cracks or voids in the concrete structure using a special pump.
Once the grout mixture is injected, it will flow in all directions, filling all the gaps or cracks within the concrete structure. The mixture then hardens and bonds the hollow parts of the concrete, thereby increasing its durability.
Simply put, grouting works similarly to applying grout on tiles. The grout is the gap between the installed tiles, which is filled with a special mixture to reduce the potential for damage.
Besides conducting observations and determining the right type of grouting, you also need to use high-quality materials for the grout mixture. One of the important materials in grouting is cement. Choose high-quality cement to ensure the quality of the grout mixture. Additionally, pay attention to how you store the cement to maintain its quality.
Generally, grouting is common in various construction projects, such as the construction of swimming pools, bridges, tunnels, building repairs, and other projects that require reinforcement or repair of concrete structures. Applying it helps increase the durability of the concrete structure, thereby enhancing its safety.

Functions of Grouting
As previously discussed, grouting is common in various construction projects because it can enhance the safety and durability of buildings. The functions of grouting include the following:
1. Enhancing the Durability of Building Foundations
One of the primary functions of grouting is to increase the durability of building foundations. Although the foundations are mostly well-built, their durability can decrease due to environmental conditions, weather changes, and the construction load they bear.
Therefore, grouting can be a solution to enhance its durability. By injecting grout into the soil voids, the soil becomes more solid and stable. This helps the foundation support the construction load, reducing the potential for structural settlement.
2. Repairing Structural Damage
Concrete is a fire-resistant building material with high durability. However, over time, concrete can experience structural damage or shrinkage.
Grouting can help repair such damages. Before applying grouting, observe to determine the type of damage to the concrete. This allows you to choose the appropriate repair method.
3. Reducing Water Seepage
One common issue in concrete structures is water seepage, which can occur anywhere, including walls and concrete roofs. The main cause of water seepage is usually cracks in the concrete and grouting can solve this issue.
As discussed earlier, grouting involves injecting a mixture that fills the gaps, voids, or cracks in the concrete. That way, cracks in your concrete can be repaired, preventing further water seepage.

4. Increasing Soil Bearing Capacity
Soil is one of the factors you must consider when building a structure. Low soil bearing capacity can endanger the stability of your building. Therefore, you need to ensure the bearing capacity at the construction site. If the soil's bearing capacity is low, you can apply grouting.
Grouting can help increase the cohesion of the soil, thereby supporting the building foundation. After that, it's advisable to conduct a follow-up observation to assess the improvement in soil-bearing capacity.
Types of Concrete Grouting
It's important to know that there are several types of grouting, each with different uses. The types of concrete grouting include the following:
1. Injection
As the name suggests, injection grouting involves injecting the grout mixture into the gaps or voids in the concrete structure under high pressure, allowing it to reach all directions. This injection process uses a special pump that can effectively flow the grout mixture into the concrete structure.
2. Chemical Grouting
Chemical grouting generally uses a low-viscosity non-particulate mixture to transform granular soil into a sandstone-like mass. The end result of applying chemical grouting is increased soil strength and reduced permeability potential.
3. Soil Grouting
Soil grouting is common for enhancing the strength of the soil beneath building foundations. The grout mixture will be injected into the soil, increasing its density and stability.
4. Preplaced Aggregate Grouting
In addition to using the grout mixture, preplaced aggregate grouting also involves using aggregates, such as stones, sand, and so on. Place the aggregates in the area to be grouted, and then carry out the grouting process. The grout mixture fills the gaps between the aggregates, making the area stronger and more stable.
