Injection Grouting
Injection grouting is like giving your concrete a shot of life. With precision and skill, a specially formulated material is injected into the cracks and crevices of aging or damaged concrete structures, filling in the gaps and restoring strength and stability.
Injection grouting is like a superhero for buildings and structures, swooping in to save the day by filling in cracks and gaps to reinforce and strengthen them. With its precision application and powerful adhesive properties, injection grouting is the trusty sidekick that helps keep structures standing strong for years to come. Whether it's preventing leaks or reinforcing foundations, injection grouting is the reliable solution that gets the job done right.
Tile Grouting Are Two Type
- 1. Cement Injection Grouting
- 2. Polyurethane Injection Grouting
Cement Injection Grouting
- This type of injection grouting involves injecting a mixture of cement and water into the cracks to fill them. Cement grouting is ideal for repairing cracks in structures such as dams, tunnels, and reservoirs.
Polyurethane Injection Grouting
- Polyurethane grouting is a fast-setting and flexible injection material that can be used for a variety of applications. It is commonly used to stabilize soil, seal leaks in basements and tunnels, and repair concrete structures.
Injection Grouting Requirement
- Injection grouting is like giving your structure a protective hug. Just like how a hug envelops you with warmth and comfort, injection grouting envelops your structure with strength and stability. By injecting grout into cracks and voids, it creates a solid bond that reinforces the structure and prevents further damage.
- Cement injection grouting is a process that involves injecting a cement-based mixture into the gaps between tiles to fill them and create a smooth, even surface.
- The mixture typically consists of cement, water, and sometimes sand or other additives to improve its strength and consistency.
- The grouting process can be done manually with a grout float or using a machine designed specifically for cement injection grouting.
- Cement injection grouting can be used for indoor and outdoor tiling applications, such as in bathrooms, kitchens, swimming pools, and exterior walls and walkways.
- The benefits of cement injection grouting include improved tile stability, durability, water resistance, and a more uniform and attractive appearance.
- The process typically takes several hours to complete, depending on the size of the area being grouted and the complexity of the tile pattern.
- It is important to properly prepare the tile surface before beginning the grouting process to ensure that the mixture adheres properly and dries evenly.
- After applying the grout, it is important to clean the surface thoroughly to remove any excess mixture and prevent staining or discoloration.
The process of how to repair a damaged wall using injection grouting technique
Application Process Cement Grouting
Cementitious grouting is a process in which a fluid cementitious grout is pumped under pressure to fill forms, voids, and cracks. It can be used in several settings including bridges, marine applications, dams, and rock anchors. The grouted mass has an increased strength, stiffness, and reduced permeability.

Can cause damage if not applied properly
- PU injection grouting is a technique used to repair cracks, voids, and leaks in concrete structures.
- PU stands for polyurethane, which is a polymer material that expands when mixed with a catalyst.
- The injection grouting process involves drilling holes into the concrete and injecting the PU material into the cracks or voids.
- The construction sector applies a variety of epoxy resins such as polyurethane, epoxy, and many more.
- As the PU material reacts with the catalyst, it expands and fills the cracks or voids, effectively sealing the structure and restoring its strength.
- PU injection grouting can be used on various types of structures, including buildings, bridges, tunnels, and dams.
- It is a quick and cost-effective method for repairing concrete structures without the need for demolition or reconstruction.
- PU injection grouting can also be used as a preventive measure to strengthen concrete structures and prevent future damage.
- The effectiveness of PU injection grouting depends on various factors, including the type and severity of the damage, the quality of the materials used, and the skill of the technicians performing the work.

Advantage and disadvantage of Cement Injection Grouting
Advantage
PU injection grouting is a cost-effective method for repairing cracked or damaged structures.
PU injection grouting is a non-invasive process that does not require the removal of the damaged structure.
The grout can be injected into small cracks and crevices, making it an effective method for repairing a variety of structures.
PU injection grouting can be used to stabilize the soil beneath a structure, which can prevent further damage.
The process can be used to repair a wide range of structures, including buildings, bridges, and tunnels.
The grout expands as it cures, which can fill voids and cracks and provide additional support to the structure.
PU injection grouting is a long-lasting solution that can extend the life of a structure.
Dis-Advantage
The process can be time-consuming, and multiple injections may be required to achieve the desired results.
The effectiveness of the method can depend on the condition of the structure and the severity of the damage.
Improper injection can lead to further damage and structural problems.
If the PU injection grout is not properly mixed or installed, it can create voids and weaken the structure.
PU injection grouting requires specialized equipment and trained professionals.
The process can be messy, and the grout can be difficult to clean up.
The cost of the process can vary depending on the size and complexity of the project.
