In the world of construction, grouting is not just about filling gaps, but also about the strength and durability of the structure. This process is important to fill voids or gaps in concrete, bricks, or other areas that need additional stability. Well, for maximum results, of course, you must use the right grouting material according to the needs of the project.
But, there are various types of materials, ranging from cement-based, epoxy, to those that are resistant to chemicals. Each has different advantages and ways to use. What are they. Let’s take a look!
Types of Grouting Materials
Each type of project requires a different grouting material. Therefore, it is important to know the differences between each type and when it is best to use them. Let’s find out the types of grouting that could be the best choice for your project!
1. Cement
Grouting is most commonly used in light to medium construction. The ingredients are simple, just a mixture of cement and water. You can adjust the viscosity level according to your needs. It is usually applied to fill voids, small cracks, and machine foundations. This cement grouting is suitable for non-critical structures with low pressure.
2. Epoxy
This type of grouting material has a very high bond strength. Made from a mixture of epoxy resin and hardener, it is highly resistant to chemicals. Commonly used in industrial areas or mechanical rooms. The application is more complicated and requires experienced technicians. However, the result is very strong and durable.
3. Polyurethane (PU)
This material is flexible and able to expand. It is commonly used to stop water leaks in underground or concrete walls. It has the advantage of being able to infiltrate narrow gaps. PU grouting is often used in the repair of old structures that have cracked or leaked.
4. Non-Shrink
This type is designed not to shrink as it hardens. It is suitable for grouting machine baseplates or structures with high dynamic loads. The material is usually a mixture of cement, silica sand, and other additives. Non-shrink grouting guarantees full contact between surfaces without any voids.
5. Chemical
This type is specially developed for specialized applications. It is usually a reactive chemical mixture that is fast drying and strong. It is used for specific requirements such as pre-stressed grouting or injection of tall concrete structures. Usually used in large and technical projects.
The Right Way to Use Grouting
Not only the material, the technique of using grouting also determines the success of the application. If the application method is wrong, the final result can fail. Understand the following steps so that the grouting process runs smoothly and the results are optimal.
1. Surface Preparation
Surfaces must be clean of dust, grease, or old material residue. Use a cleaning tool or high-pressure water spray. Make sure the surface is slightly moist, but not wet. This is important to maximize the bonding power of the grouting material to the surface.
2. Material Mixture
Follow the manufacturer’s instructions precisely. Do not overestimate the water to material ratio. Use a low-speed mixer for a homogeneous mixture. Mixing time is usually about 3-5 minutes, depending on the type of material.
3. Application Process
Carefully pour the grouting into the intended area. Make sure there is no air trapped in it. Use tools such as funnels or hoses to reach narrow areas. Application should be a single pour and continuous.
4. Curing Stage
Grouting needs time to fully harden. Protect the area from direct sunlight or excess water for 24-48 hours. Use curing compound or cover the surface with plastic. This will keep moisture out and ensure maximum results.
That’s a complete discussion about the various grouting materials and how to use them. Although it may seem simple, choosing the right materials can make a big difference to the strength and durability of a building structure. All materials have their own roles that cannot be replaced.
