Bitumen, also known as asphalt, is a sticky, black and highly viscous liquid or semi-solid form of petroleum. Thanks to its waterproofing qualities, it is widely used in construction. Bituminous membranes are perfect for waterproofing roofs, basements, below-ground structures, bridges and other structures.

Torch-applied Bitumious Membranes
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.
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 Tapes
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 LAM (Cold-applied, Liquid -applied Membrane)
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
- Renovation projects
- Detailing
- Typically used for residential and industrial buildings
- As an adhesive to bond lightweight thermal insulation
Advantages
- No torch needed
- Fully-bonded, seamless system
- Crack-bridging capability
- Safer, faster installation
