DUMBELL TYPE PVC WATER STOPPER
1. **Design**: The dumbbell-type PVC water stopper is shaped like a dumbbell, with a central bulbous section connected to two cylindrical arms on either side. This design allows the water stopper to be inserted into a pre-formed groove or channel in the concrete joint, creating a watertight seal.
2. **Material**: PVC (polyvinyl chloride) is the primary material used in the construction of dumbbell-type water stoppers. PVC offers excellent flexibility, durability, and resistance to water, chemicals, and weathering, making it well-suited for use in concrete construction applications.
3. **Flexibility**: The dumbbell shape of the water stopper allows it to flex and conform to the contours of the joint, ensuring a snug fit and an effective seal. This flexibility accommodates movements in the concrete structure due to temperature variations, settlement, or seismic activity without compromising the integrity of the seal.
4. **Installation**: Dumbbell-type PVC water stoppers are typically installed during the pouring of concrete, with the water stopper positioned in the center of the joint groove before the concrete is poured. The concrete is then poured around the water stopper, encapsulating it and forming a secure seal. Alternatively, they can be retrofitted into existing joints by cutting a groove and inserting the water stopper.
5. **Applications**: Dumbbell-type PVC water stoppers are used in a variety of concrete construction applications, including:
- Water Retaining Structures: Such as reservoirs, dams, water treatment plants, and swimming pools to prevent water leakage and seepage. - Below-Grade Structures: Such as basements, underground parking garages, and tunnels to protect against groundwater infiltration. - Infrastructure Projects: Such as bridges, culverts, and retaining walls to ensure the longevity and stability of the structure by preventing water-induced deterioration.
6. **Advantages**: Dumbbell-type PVC water stoppers offer several advantages, including ease of installation, resistance to corrosion and deterioration, compatibility with various concrete structures, and cost-effectiveness compared to traditional water stop materials like rubber or metal.

Pvc Water Stopper Dumbbell Type
Absolutely! Here’s a clear, short technical + commercial style overview of a PVC Water Stopper Dumbbell Type for you:
💧 What is a PVC Water Stopper Dumbbell Type?A PVC Water Stopper (Water Bar) is a flexible strip made of Polyvinyl Chloride (PVC), embedded in concrete joints (expansion / construction / contraction joints) to prevent water seepage.
The “Dumbbell Type” refers to its shape — it has bulges (bulbous ends) on both sides, resembling a dumbbell, which anchor better into the concrete.
⚙️ Key Features✅ Material:
-
High-grade PVC compound
-
UV, ozone, chemical, and alkali resistant
✅ Design:
-
Dumbbell shape allows it to accommodate movement in the joint (expansion & contraction)
-
Ribs on sides help interlock with concrete
✅ Function:
-
Acts as a physical barrier to stop water from crossing through the joint.
| Parameter | Typical Values |
|---|---|
| Width (size) | 150 mm, 200 mm, 230 mm, 250 mm, 300 mm |
| Thickness | 5 mm to 10 mm |
| Bulb size (dumbbell) | 20 mm to 30 mm |
| Tensile Strength | ≥ 12 N/mm² |
| Elongation at break | ≥ 300% |
| Water absorption | <0.15% |
| Color | Typically Blue, Green, Yellow |
✅ Water retaining structures:
-
Reservoirs, dams, canals
-
Water treatment plants, swimming pools
✅ Water excluding structures:
-
Basements, tunnels, parking structures
✅ Expansion & contraction joints in RCC construction.
🆚 Dumbbell vs Other Types| Type | Use Case |
|---|---|
| Dumbbell Type | For joints with moderate movement & high water pressure. Most common for expansion joints. |
| Center Bulb Type | Has large bulb in center — for large movements (thermal expansion joints, seismic areas). |
| Flat Rib Type | For construction / contraction joints with minimal movement. |
"PVC Water Stopper Dumbbell Type — made from premium PVC compound, designed to provide long-lasting watertight seals in expansion joints. Available in sizes from 150 mm to 300 mm, suitable for high water head structures."

Pvc Water Stopper Dumbbell Type
✅ Here’s a neat, focused technical + commercial note on “PVC Water Stopper Dumbbell Type” for your use (for catalog, quotation or client explanation):
💧 PVC WATER STOPPER – DUMBBELL TYPE 📌 What is it?A PVC Water Stopper Dumbbell Type is a specially designed flexible strip made of high-grade Polyvinyl Chloride (PVC), embedded across construction or expansion joints in RCC structures.
It acts as a physical barrier to prevent water from seeping through the joints.
✅ Material:
-
Flexible PVC compound, resistant to chemicals, chlorides, sulphates, acids & alkalis
-
UV stabilized (for long life even in exposed applications)
✅ Shape:
-
“Dumbbell” shape has bulbous projections on both sides which get anchored firmly in concrete.
-
The central flat portion allows minor movement (contraction / expansion) without cracking.
✅ Functions:
-
Stops passage of water through joints.
-
Absorbs minor movement / vibration in the structure.
| Parameter | Values |
|---|---|
| Width (Size) | 150 mm / 200 mm / 230 mm / 250 mm / 300 mm |
| Thickness | 5 mm to 10 mm |
| Bulb Size | 20 mm to 30 mm |
| Tensile Strength | ≥ 12 N/mm² |
| Elongation at Break | ≥ 300% |
| Water Absorption | < 0.15% |
| Color | Blue / Green / Yellow (or as required) |
✅ Water Retaining & Excluding Structures such as:
-
Reservoirs, dams, canals, swimming pools, water tanks
-
Basements, tunnels, subways
-
Treatment plants (STP / ETP)
✅ Ideal for expansion & contraction joints, where joint opening / closing is moderate.
✅ Advantages✔ 100% leak-proof joint protection
✔ Easy to weld on-site by hot welding gun or solvent cement (joining two ends)
✔ Long life — corrosion & maintenance free
✔ Cost-effective compared to metallic water bars
"PVC Water Stopper Dumbbell Type – durable, flexible & economical solution for watertight RCC joints. Available in sizes 150 mm to 300 mm."
