Matters need to attention in waterstop storage & installation

• In waterstops transportation and storage, keep packages of waterstops unbroken and store them in places where are dry and well-ventilated. Keep waterstops away from direct sunlight, acids, alkalis, oils and organic solvents.
• Waterstops cannot be exposed to sun directly for long time and keep waterstops away from rain. Don't make waterstops contact with chemicals of strong pollution.
• If waterstops are packaged in coils, they should be uncoiled several days before installation.
• There are many sharp stones and steel reinforcing bars in concrete, so operators should be careful for fear that these articles damage waterstops in installation process.
• Make waterstops adhere to concrete surfaces smoothly in waterstops location. Avoid waterstops overturn and distortion, and adjust waterstops in time if they are improper.
• Prevent waterstops displacement to ensure the waterproof performance in waterstops fixation.
• Vibrate concrete thoroughly in the concrete pouring process to make waterstops and concrete adhere firmly.
• Plastic waterstops can be fixed to concrete surfaces by cementation or hot weld to guarantee firm joints.

Rubber waterstops have good sealing performance by taking advantage of rubber high elasticity and compression deformation property.

Swelling waterstops have better sealing and waterproof performance thanks to water expanding waterstop bars.
