Maintainable Swelling Injection Water Bar System
Newton 304 PolyProof Inject combines the grouting and resin injection capabilities of Newton 302 InjectionHose with the swelling capabilities of Newton 303 PolyProof. The resulting hybrid provides a very high performance water bar system used for the sealing of construction joints within retained concrete structures.
The system offers many benefits over conventional water bars, especially that in addition swelling when in contact with water, it also has the ability to grout poorly compacted concrete and seal leaking construction joints, post construction. The hydrophilic thermo-plastic elastomer outer casing will seal the joint against leaks by swelling to up to 400 times its original size when in contact with water, sealing the joint fully and reliably.
Benefits of Micro-Ports
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 sealing 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 after injection 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
- Primary swelling water bar to seal the joint against leaks through the construction joint.
- Post construction grouting and leak sealing of construction joints to earth retained structures.
The following construction joints can be waterproofed with Newton 304 PolyProof Inject:
- Raft – Raft
- Raft – Wall
- Wall – Wall
- Slab – Steel Piled Cut off Wall
- Wall – Deck
- Slab – Slab
- Slab – Wall
Key Benefits
- The outer casing Swells to up to 400 times to quickly seal leaks at construction joints.
- 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.
