Bituminous Membrane

Once applied, Sika’s bituminous membranes are a thin layer of watertight material fully-bonded to the surface. It is a flexible system, able to maintain its waterproof capacity without causing cracks.

See the general bituminous membrane build-up below.

Main Uses

• Retaining walls, basements and below-ground structures
• Flat roofs under protective layers of ballast 
  
• Balconies and terraces under tiles
• Wet areas
• Underground car parks
• Bridges
• Raft slabs and foundations
• Protection of various substrates in a wide range of applications
  

Advantages

• Fully-bonded system
• Resistant to the most extreme weather conditions
• Ease of maintenance
• Excellent mechanical properties
• High resistance to mechanical damage and punctures

Self-adhesive bituminous membranes are covered by a release liner, which is removed during application.

Main Uses

• Wood substrates
• Flammable areas
• Small areas, vertical surfaces or those areas with difficult access
• Retaining walls, basements and below-ground structures

Advantages

• No torch needed
• Safer, faster installation
• No special equipment needed
• Excellent adhesion, even at low temperatures

Bitumen liquid-applied membranes are the perfect solution for seamless, fully-adhered and safe systems. They are polymer-modified bitumen emulsions which require no torch or flame to be applied. They are available as water-based or solvent-based coatings.

Main Uses

• Below-ground areas facing ground moisture, such as foundations  
  
• Wet areas  
  
• Swimming pools  
  
• Renovation projects
• Detailing
• Typically used for residential and industrial buildings
• As an adhesive to bond lightweight thermal insulation boards

Advantages

• No torch needed
• Fully-bonded, seamless system
• Crack-bridging capability
• Safer, faster installation

Sika also has self-adhesive, polymer-modified bituminous sealing tapes which are laminated with aluminum foil on the upper side and contain no reinforcement.  

Main Uses

• Sealing and repairing building cracks, roofs, sheet metal work, bituminous felts and other types of roofing sheet membranes
  

Advantages

• No torch needed
• UV-resistant
• Excellent watertightness
• Multi-purpose tape
• Flexible and easy to apply
• Safer, faster installation

Bitumen hot melt is a polymer-modified bitumen, either elastomeric or plastomeric, packed in a solid block state. For application, the block is heated and applied onto the substrate, forming a fully-bonded waterproofing layer.

Main Uses

• Roofing, such as green roofs
• Podium decks
• Balconies and terraces
• Car parking garages
• Civil engineering projects, such as foundations, slabs and retaining walls
• Bridges and access roads
• As an adhesive to bituminous sheets or insulation boards, for example
  

Advantages

• Solid-modified bitumen
• Provides a strong, lasting bond
• In situ waterproofing - local application exactly where it's needed
• Excellent alternative for areas with many complex details
