Injection unit for cementitious grout
An Injection Unit for Cementitious Grout is a specialized system designed to mix and inject cement-based grouts into soil, rock formations, concrete structures, or behind tunnel linings. These units are widely used in geotechnical engineering, tunneling, foundation repair, and structural reinforcement projects.
A cementitious grout injection unit is a purpose-built system designed for mixing, pressurizing, and precisely placing cement-based grouts in applications like soil stabilization, rock anchoring, void filling, and structural repairs.

Applications of injection unit for cementitious grout:
Tunnel Construction:
Used for soil stabilization, water sealing, and rock consolidation.
Ensures the stability and safety of tunnels during and after excavation.
Mining Operations:
Used for ground support, water control, and shaft sealing.
Enhances the safety and productivity of mining activities.
Civil Engineering:
Applied in dam foundations, slope stabilization, and underground construction.
Provides long-term durability and stability to structures.
Structural Repair:
Used for repairing cracks in concrete structures, sealing joints, and reinforcing weakened areas.
Extends the lifespan of buildings, bridges, and other infrastructure.

Types of Cementitious Grout Used:
Type | Application |
---|---|
Cement + Water Grout | Basic applications like crack sealing |
Cement + Sand + Additives | For filling large voids or structural support |
Microfine Cement Grout | Penetrates fine cracks and porous media |
Expansive Cement Grout | Prevents shrinkage and fills gaps tightly |
Sulfur-Resistant Cement Grout | Used in aggressive environments (e.g., sewage tunnels) |
