Maintainable Injection Water Bar System
Newton 302 InjectionHose is a high performance injectable water bar system used for the sealing of construction joints within retained concrete structures. The system offers many benefits over conventional water bars, especially its ability to grout poorly compacted concrete and by offering a maintainable solution that allows for resealing of the construction joint, post construction.
The injection hose system features Micro-Ports equally spaced over its entire circumference giving the hose optimum grouting characteristics. The microscopic Micro-Ports open at 1 bar and the injected material is then allowed to perform its task of penetrating all areas of the construction joint that require grouting. As a result, a more secure and longer lasting seal of the construction joints is achieved. The Micro-Ports prevent any infiltration of concrete silt and foreign bodies into the injection hose itself.
After successful injection, the reduction in pressure causes the Micro-Ports to close. The injection channel can then be flushed out without any threat of any injection material seeping back into the injection hose. There are no limitations regarding the choice of grouting material, all currently available grouting materials may be injected using the Newton 302 InjectionHose.
When correctly installed, impressive results can be achieved using low levels of grouting material. Flushing the system with water allows for repeated injection of grouts or resins.
Typical Applications
Post construction grouting and leak sealing of construction joints to earth retained structures. The following construction joints can be waterproofed with Newton 302 InjectionHose:
- Raft – Raft
- Raft – Wall
- Wall – Wall
- Slab – Steel Piled Cut off Wall
- Wall – Deck
- Slab – Slab
- Slab – Wall
Key Benefits
- Provides post construction grouting of poorly compacted concrete at construction joints.
- Injection of resins for the sealing of leaks identified post construction.
- No kicker or rebate required, reducing site labour costs.
- Can be injected with all currently available grouting materials (PUR resin, PUR foam, EP resin, polymer gel matrix, ultra-fine cement grout).
- Repeated injection possible (with polymer gel matrix and ultra-fine cement).
- Injection possible to 30m sections.
- Guaranteed continual flow of the injection material due to the star-shaped interior geometry, even if the hose follows sharp bends.
Suitable Substrate
Static construction joints in poured concrete retained structures.
