SwellGuard PWB
Polymeric Swellable Water Bar
A polymer-based swellable waterstop designed for sealing construction joints in concrete structures. Upon contact with water, the material expands to form a watertight seal that prevents water infiltration through construction joints in basements, water tanks, tunnels and other underground structures.
Features and Benefits
- Hydrophilic TPE technology provides controlled swelling on contact with water.
- High elongation helps accommodate movement at concrete joints.
- Excellent flexibility for installation around typical joint configurations.
- Swelling helps seal and block potential water pathways through construction joints.
- Suitable for use in potable-water exposure conditions based on tested swelling performance.
- Maintains its polymeric structure during repeated wetting and drying cycles.
- Available in different cross-sectional sizes to suit project requirements.
- Easy to install using a suitable compatible fixing method.
Area of Applications
- Construction and cold joints in reinforced concrete structures
- Basements and underground structures
- Water retaining and water-excluding concrete structures
- Water tanks and reservoirs
- Sewage and wastewater structures
- Concrete retaining structures
- Tunnels and underground infrastructure
- Pipe penetrations and other suitable concrete joint details
