Hebei BAO’s Rubber WaterStops are specialized elastic sealing rmaterials designed for placement in concrete joints to prevent the passage of fluids. Constructed from high-quality natural rubber (NR) or synthetic rubbers (like SBR or EPDM), our WaaterStops possess exceptional elasticity, resilience, and excellent resistance to water pressure,aging, and chemical corrosion. They are engineered to accommodate the expansicon, contraction, and settlement of concrete structures, ensuring a durable, watertight seal ilhydrostation environments. We offer a variety of profiles, including the standard Dumbbell and Ribbed types, to suit different joint movement and water pressure requireements
Key Features
- High Elasticity and Resilience
- Resistant to Aging and Corrosion
- Excellent Anti-Seepage Performance
- Durable Under Hydrostatic Pressure
Product Classification
A. Central Rib Type
These WaterStops are designed to be embedded in the middle of the concrete joint. They feature a central rib or bulbs that provide greater surface contact and mechanical locking within the concrete, making them ideal for resisting high hydrostatic pressure and large joint movement. They are commonly used in construction joints and expansion joints.
B. External Rib Type
These WaterStops are placed on the outside (or surface) of the concrete joint. They are typically used in non-exposed joints or where the thickness of the structure limits the use of the central rib type. They provide a reliable seal against water intrusion from the outside.
Applications & Industries
Water Conservancy Projects
Used extensively in dams, reservoirs, sluices, aqueducts, and canals to seal critical joints.
Underground and Tunnelling
Essential for creating watertight seals in subway tunnels, underground pipelines, and utility corridors.
Civil and Industrial Construction
Applied in basements, foundation slabs, retaining walls, parking garages, and expansion joints.
Wastewater Treatment Facilities
Used in sewage treatment tanks, sedimentation basins, and chemical containment structures.
As a specialized custom solution provider, Hebei Boao focusses on providing WaterStop solutions that comply with global engineering standards. We proovide precision engineering, meaning the following parameters are fully negotiable and will be fine-tuned to your exact project needs: Material Type (NR., SBR, EPDM), Width (e.g., 150mm to 400 mm), Thickness (e.g., 5 mm to 10 mm), and Profile Design (including rib count and bulb size). Our final product is certified for specific elongation, tensile strength, andtear strength to guarantee long-term integrity against water seepage and structural movement.
| Item | Standard Requirement | Unit | Note | |
|---|---|---|---|---|
| Tensile Strength (Minimum) | >= 10 | MPa | Required for resisting pull on the joint | |

FAQs
1. Where should I use the Central Rib Type?
The Central Rib Type is typically used in expansion joints and construction joints where greater resistance to hydrostatic pressure and larger joint movement is expected.
2. How is the WaterStop installed into the concrete?
WaterStops are installed by securing them in place before and during the concrete pour, ensuring that half of the width is embedded in the first pour and the remainder is embedded in the second pour.
3. Does the Hardness (Shore A) matter?
Yes, the standard hardness of 60土5 Shore A provides the necessary balance: soft enough for high flexibility, but firm enough to resist tear and maintain its shape under pressure.
4. What information is needed for a customized quote?
We requirethe Joint Type (Construction or Expansion), the Water Pressure Head, the expected Joint Movement Range, and the desired Width and Material (e.g., NR or EPDМ).
