Watertight swelling system SikaSwell®

SikaSwell® is an innovative sealing system for various types of joints, based on materials that swell upon contact with water. These specially formulated Sika profiles and sealants react when exposed to moisture, increasing in volume and effectively filling cracks and cavities. This achieves long-lasting waterproofing and reduces the risk of water penetration into the structure.

Main advantages

• Self-swelling effect
  Upon contact with water, the material expands and creates a watertight seal, even with slight movements and irregularities.

• Universal application
  Suitable for various construction substrates such as concrete, steel, and others, including horizontal and vertical joints.

• Easy and quick installation
  It is easily installed using standard tools, often using a special SikaSwell® adhesive/sealant product for fixing.

• Resistance to hydrostatic pressure
  Effectively prevents water ingress even under higher water pressure, making it ideal for underground and water facilities.

• Flexibility and cost-effectiveness
  The system can compensate for small irregularities and movements without the need for additional or costly installation operations.

Applications

• Construction and working joints
  Ideal for construction connections in underground parts of buildings, foundations, basements, concrete slabs, and walls.

• Pipe and cable penetrations
  The system provides reliable sealing around installation openings, preventing water penetration into the building or facility.

• Reservoirs and pools
  Used for sealing concrete structures containing water, where stable waterproofing is critically important.

• Tunnels and underground facilities
  The swelling profiles ensure watertightness and protect structures from groundwater penetration.
