Waterstop Selection Suggestions

Waterstop Selection Suggestions
You should take many factors into account in waterstop selection, such as the importance of structures, deformation amount of movement joints, water pressure, waterstop working conditions and economic factor. Some suggestions are shown below.

• In general, natural rubber waterstops are widely used.
• Neoprene waterstop is suitable meeting corrosive media, such as weak acid and weak alkali.
• Nitrile rubber waterstop is suitable meeting oil media.
• Neoprene waterstop is suitable for the temperature range of -45 °C to +100 °C.
• Natural rubber waterstop is suitable for the temperature range of -60 °C to +80 °C.
• EPDM waterstop is suitable for the temperature range of -50 °C to +150 °C.

PVC waterstops are widely used in many concrete structures because of good sealing performance and low water absorption.

Steel-edge water stops can adhere to concrete surfaces firmly because of the galvanized plates.
