Cast Iron Striped Copper Metal Water Stopper, Color : Black

Water stoppers (also known as waterstops) are critical components used in construction to prevent the passage of water through concrete joints, especially in water-retaining or water-excluding structures like basements, tunnels, dams, reservoirs, water tanks, and retaining walls. Here are the main advantages of water stoppers:

Water stoppers seal construction joints, expansion joints, and movement joints, preventing water from passing through. This is vital for:

  Underground structures

  \r

• \r

  Water tanks and reservoirs

  \r

• \r

  Sewage treatment plants

By keeping water out, water stoppers help protect the steel reinforcement (rebar) from corrosion, thus increasing the durability and life of the structure.

In structures like sewage treatment plants, water stoppers prevent contaminated water from leaking into the surrounding soil and groundwater.

Many modern water stoppers (like PVC, rubber, or bentonite types) are designed for easy installation during construction. They are embedded in the concrete joints during pouring.

Certain types of waterstops (especially those used in expansion joints) allow for controlled movement due to temperature changes, seismic activity, or settling, without compromising water tightness.

Though they add to initial construction cost, water stoppers reduce maintenance costs and potential damage from water leakage, making them economically beneficial over time.

Different materials are available (PVC, rubber, HDPE, metal, swellable bentonite, etc.), allowing engineers to choose the best fit for:

• \r

  Freshwater vs. chemical exposure

• \r

  Internal vs. external joints
