Product Q&A

Q:What is the working principle of the water-swellable waterstop strip?

The water-swellable waterstop strip gradually expands in volume upon contact with water, filling gaps in concrete construction joints, pipe joints, and other locations, forming a physical water barrier to achieve water sealing.

Q:What is the difference between PZ(BF) Type (red) and PN(BW) Type (black)?

The PZ(BF) Type (red) is a preformed material with certain hardness and elasticity. Its shape remains stable after expansion and is suitable for regular and flat construction joints. The PN(BW) Type (black) is a soft, sticky material that can conform to irregular surfaces and is suitable for pipe joints, complex joints, and other applications.

Q:How soon can we receive a quotation after sending an inquiry?

Upon receiving clear and complete inquiry information (such as drawings, specifications, and quantities), we typically provide an initial quotation or proposal within 24 hours. For complex projects, we will communicate the required time with you promptly.

Q:Is the product quality guaranteed?

Yes. We provide quality assurance for our products upon delivery. Strict control standards are implemented in all stages from raw material procurement to manufacturing, ensuring product performance meets technical specification requirements.

Q:What management system certifications does your company have?

Our company has established and operates a comprehensive management system and has obtained quality management system certification (e.g., ISO 9001), environmental management system certification (e.g., ISO 14001), and occupational health and safety management system certification (e.g., ISO 45001).
