Water Stopper

Cast water barrier water stopper for liquid-retaining concrete wall forms.

Formwork Water Stopper (also known as Water Barrier Nut) is a cast iron center connection nut used with tie rods in water-retaining structures, basement walls, or sewage treatment tanks. It features an integrated center steel disc that acts as a physical barrier to block water seepage along the tie rod channel through the concrete wall.

Key Features

• Integrated center flange disc prevents capillary water transfer
• Cast threads on both ends for connecting outer tie rods
• Ductile iron structure matches tie rod tensile ratings
• Leaves no metal parts protruding from the finished concrete surface
