SL 668 Expanding PU Foam – An Effective Waterproofing Solution

SL 668 Expanding PU Foam, also known as foam SL 668, is a specialized product designed for waterproofing and sealing cracks in various construction structures. With superior performance compared to conventional adhesives, this product is widely trusted and used by contractors for a variety of waterproofing projects.

Introduction to SL 668 Expanding PU Foam

SL 668 Expanding PU Foam is a high-quality adhesive produced in Taiwan by the renowned brand Shenglong. Known for its cutting-edge waterproofing technology, Shenglong is a global leader in this industry. SL 668 is a one-component polyurethane foam with high expansion properties, capable of expanding between 22 to 34 times its original volume when injected into cracks. This expansion ensures effective waterproofing and crack sealing. SL 668 is an essential solution for addressing water leaks and repairing cracks in various construction projects.

Applications of SL 668 Expanding PU Foam

SL 668 Expanding PU Foam is widely used for addressing waterproofing issues such as:

• Sealing cracks in walls, ceilings, concrete, elevator pits, and basements.
• Waterproofing construction joints, expansion joints, and settlement joints.
• Handling both positive and negative waterproofing solutions.
• Repairing leaks in basements, elevator shafts, high-rise buildings, dams, hydropower plants, and storage tanks.

After being injected into the cracks, the foam expands rapidly and cures, blocking water leaks effectively. Here are some key applications of the product:

• Waterproofing cracks in concrete, walls, and ceilings.
• Sealing construction joints and expansion joints.
• Addressing both positive and negative waterproofing scenarios.
• Injecting into elevator shafts, basements, and high-rise structures.

Outstanding Technology of SL 668 Expanding PU Foam

SL 668 Expanding PU Foam is a top choice for customers due to its remarkable waterproofing performance. Here are some of its standout features:

• High expansion rate: SL 668 expands up to 16 times its original volume, ensuring that it fills cracks thoroughly, providing maximum waterproofing efficiency.
• Durability and strength: After expanding, the foam becomes solid and robust, not only preventing water leaks but also reinforcing the cracked structures.
• Rapid expansion: This allows contractors to quickly address leaks, saving time and making the waterproofing process more efficient.
• Water resistance: With polyurethane as its primary component, SL 668 offers excellent water resistance, ensuring long-lasting waterproofing for your construction projects.

SL 668 Expanding PU Foam and Its Construction Efficiency

SL 668 Expanding PU Foam is not only highly expandable but also provides strong bonding after curing. This helps seal cracks and prevents water penetration effectively. The rapid expansion rate enables the foam to stop water flow immediately, and the product has a long lifespan, ensuring sustainable waterproofing for any construction project.

How to Apply SL 668 Expanding PU Foam

To apply SL 668 Expanding PU Foam, the following tools are needed: high-pressure injection pump or syringe, injection needles, PU foam SL 668, drill, and drill bits.

1. Surface preparation: Clean and identify cracks that need to be sealed.
2. Drilling: Use a drill to create holes at a 45° angle along the crack. The holes should be spaced about 15cm to 30cm apart for optimal sealing.
3. Install injection needles: Insert and tighten the injection needles into the drilled holes.
4. Foam injection: Use a high-pressure injection pump (3000 to 6000 PSI) or a specialized syringe to inject SL 668 Expanding PU Foam into the cracks. Begin injecting from the lowest point.
5. Expansion and sealing: As the foam is injected, water will gradually seep out, and the foam will expand to fill the cracks.
6. Maintain pressure: Keep the pressure for 1 to 3 minutes to allow the foam to penetrate deeply into the cracks for maximum waterproofing efficiency.

By following these steps, contractors can ensure that the SL 668 Expanding PU Foam effectively seals cracks and provides long-lasting waterproofing.
