Grouting Material

• The material which is used for grouting should be non-shrinkable.
• The grouting material should expand when it is filled in the cracks or voids.
• The grouting material should be capable to sustain compressive loads.
• It should have good tensile strength and vibratory load resistance.
• It should richest the entry of moisture and easy to apply.

Different Types of Grouting Materials

1. Cement grout or cement-based mortars.
2. Cement sand with additive grouts.
3. Polymer Modified cement grout.
4. Epoxy resin.

Advantages of Injection Grouting

1. Injection grouting is very easy and convenient to use.
2. Injection grouting is an environment-friendly process.
3. It is suitable for repairing cracks and filling voids in structural members.
4. It provides strength and stability to the masonry structural members.
5. The injection grouting process is economical.
6. There is no wastage of material in the injection grouting process.

Process of Injection Grouting

• Drilling Holes on the Surface
• Cleaning the Holes and Cracks
• Sealing the Cracks Between the Holes.
• Grout the Hose Connections
• Injecting Grout in the Cracks

Step - 1. Drilling Holes on the Surface

Step - 2. Cleaning the Holes and Cracks

Step - 3. Sealing the Cracks Between the Holes

Step - 4. Grout the Hose Connections

Step - 5. Injecting Grout in the Cracks

Applications of Injection Grouting

1. It is used to reduce or fill the cracks or voids in the structural members.
2. It is generally used for repairing the cracks in walls columns and other structural members.
3. It is also used for providing finishing to the wall.
4. Injection grouting is used to repair the damage in the structural or masonry members.
5. Injection grouting is best suitable for honeycombing.
6. Injection grouting is used to repair and strengthening the damaged areas.
7. It is also used for making walls waterproof.

Types of Injection

1. Subcutaneous (into the fat layer between the skin and muscle)
2. Intramuscular (deep into a muscle)
3. Intravenous (through a vein)
