An injection tube, also referred to as an injection hose, is a crucial component in systems designed to seal joints in concrete structures. These systems are especially important for below-grade structures.
Understanding Injection Tube Systems
Injection Tube Systems, sometimes called Injection Hose Systems, are primarily used to seal structural and cold joints in concrete. These systems are particularly effective in below-grade concrete structures.
Key Applications:
- Tunnels: Preventing water ingress through joints.
- Tanks: Ensuring watertightness of concrete tanks.
- Parking Garages: Sealing joints to protect against water damage.
How Injection Tube Systems Work
These systems involve:
- Installation: Injection tubes are embedded within the concrete structure at construction joints.
- Injection: When a leak is detected, a sealant (usually a resin) is injected into the tube.
- Sealing: The sealant flows through the tube and seals the joint, preventing water infiltration.
Benefits of Injection Tube Systems
- Effective Sealing: They provide a reliable method for sealing joints.
- Durability: They ensure long-term protection against water damage.
- Versatility: Applicable in various below-grade concrete structures.
- Targeted Repairs: Sealant is directed precisely to the problem area.
Types of Injection Tubes
While there are different materials and designs, all injection tubes function to allow for the injection of sealants.
| Feature | Description |
|---|---|
| Material | Typically made from flexible, durable materials like PVC or rubber. |
| Design | May include small ports along their length for sealant distribution. |
| Function | Allows for targeted injection of sealing resins. |
| Application | Primarily used in concrete structures for sealing joints and cracks. |
Injection tube systems offer a proactive approach to manage water infiltration by targeting problematic areas in concrete structures, making them indispensable in modern construction and repair.
