Frequently Asked Questions
What is the primary function of a rubber waterstop?
It is used in concrete joints to prevent water leakage by creating a physical barrier and increasing the moisture path within the joint.
Can the size of the waterstop be customized?
Yes, we offer customized widths (150mm-500mm+) and thicknesses (3mm-20mm) to meet specific construction requirements.
What is the difference between CB and CP types?
CB types feature a center hole to accommodate greater joint movement, while CP types are solid and used for points with less expansion.
How is the product packaged for international transport?
Usually, it is packed in 20m or 25m rolls in durable bags or as per customized shipping requirements.
Are test reports available for quality assurance?
Yes, full test reports based on GB/T18173.2-2014 standards are available for all our rubber waterstop products.
Does this material handle extreme cold?
Yes, it has a low brittleness temperature of -40ºC to -50ºC, making it suitable for cold climate applications.
