SikaSwell S-2 Hydrophilic Joint Sealant
SikaSwell S-2 is a 1-part polyurethane hydrophilic sealant engineered for professional construction applications. This advanced joint sealing solution expands in contact with water, creating a robust waterproof barrier in concrete structures, building joints, and penetrations.
Key Performance Features
Water-Activated Sealing Technology
The unique hydrophilic formulation responds to moisture by swelling, automatically filling gaps and creating an impermeable seal. This makes it ideal for:
- Concrete joint sealing and construction gaps
- Structural penetrations and movement joints
- Thermal expansion joints in building envelopes
- Moisture-prone areas requiring permanent waterproofing
Elastic Movement Absorption
Permanent elasticity allows the sealant to accommodate structural movements, thermal fluctuations, and settlement without losing waterproofing integrity. This flexibility prevents cracks and maintains long-term performance in dynamic building environments.
Exceptional Adhesion & Durability
Bonds securely to common construction materials including concrete, mortar, aluminium, steel, and plastics. The sealant resists:
- Extreme temperature variations
- UV radiation and weathering
- Chemical exposure and ageing
- Structural stress and movement
Technical Specifications & Compliance
SikaSwell S-2 meets rigorous European and national building regulations with full CE marking and certified technical documentation. Professional applicators benefit from comprehensive technical support, including application guidance, substrate preparation specifications, and on-site assistance when required.
Ideal For Professional Use
Recommended for construction contractors, specialist waterproofing firms, building rehabilitation projects, and certified technical applicators requiring proven, quality-assured materials backed by a leading global construction chemistry manufacturer.
