A PVC Water Stopper 2305 mm is a flexible, durable, and waterproof strip used to seal construction joints in concrete structures and prevent water leakage or ingress through those joints. The dimensions 230 mm wide and 5 mm thick indicate it's a flat-type waterstop, suitable for various applications depending on its profile (dumbbell, center bulb, or surface type).

Profile Type | Use |
---|---|
Dumbbell Type | For expansion joints, allows some movement |
Center Bulb Type | Used when larger movement is expected, central bulb flexes with joint |
Flat Ribbed / Surface Type | Used on the surface of slabs or walls; easy to fix in vertical applications |
Excellent flexibility and elongation
Corrosion and chemical resistant
Easy to weld or join on-site
Long-lasting and low maintenance
Available in custom lengths and profiles
Ensure it's placed centrally in the joint (for embedded types)
Use PVC welding machine or heat gun for on-site joints or corners
For surface-mounted types, fix with nails or adhesive before second pour
Protect during pouring to avoid displacement or damage
