High Quality Hydrophilic Rubber Waterstop

Water swelling water stop strip is a unique new rubber product. It is the collective name of putty type water stop strip and product type water stop strip with water swelling performance. This kind of rubber produces 2-3 times expansion deformation after encountering water, and fills all irregular surfaces, voids and gaps of the joints. At the same time, it generates enormous contact pressure to completely prevent leakage.

Description

Material:Natural Rubber, Bentonite, Volclay

Color:Black,Red,etc

Expansion Rate:150%-600%

Width:12mm-50mm

Size:25mm*20mm 20mm*15mm, 20mm*10mm 20*5mm ect Or Customzied

Feature:Hydrophilic,High Expansion

Main characteristics

The material has excellent hydrophilic and expanding properties, when in contact with water the volume can expand several times to the original state, effectively filling the dynamic seams and resisting the penetration of hydraulic pressure. Its chemical corrosion resistance, outstanding resistance to ageing, is suitable for the acid-alkali environment and long-term immersion conditions, and its performance in dry and wet cycles is stable, there is no discharge, does not affect water quality.

Technical advantages

This waterstop has the ability to “in contact with water, i.e. swelling, dynamic adaptation”, can automatically adjust the sealing pressure with the movement of the seam to compensate for the failure of the traditional waterstop due to contraction or vibration of concrete. Convenient installation, can be simultaneously filled with concrete, forming a common watertight system, which significantly increases the reliability and lifetime of watertight design.
