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.
Build-Up of Sika Bituminous Membranes
Bituminous membranes are a versatile technology. The correct combination of raw materials and layers can offer a variety of performance and durability aspects, therefore allowing it to be used in a wide range of applications. This is just one example of the build-up of bitumen membrane.

SikaShield® Product Range
SikaShield® is available in a wide range of options to suit many possible systems and designs. Our membranes are made of a selective combination of polymers to achieve better properties, such as cold flexibility, heat resistance, viscosity and softness.
The correct choice of bituminous compound is important to keep the waterproofing function across different temperatures and weather conditions (wind, snow, hail). Therefore, various types of products are offered:
SikaShield® P
Torch or self-adhesive bituminous membranes made of mainly plastomeric polymers, such as polyethylene, polypropylene, virgin or recycled APAO, etc.
- Ideal for hot climates
- Excellent heat resistance
- Wide hardness range
SikaShield® E
Torch or self-adhesive bituminous membranes made of mainly elastomeric polymers, such as SBS, SIS, resins, etc.
- Ideal for cold climates
- High flexibility at low temperature
- Excellent elastic recovery and fatigue resistance
SikaShield® W
Wet-applied bituminous membranes made of special polymers and fully-bonded to the concrete substrate by a special modified cement-based adhesive, SikaShield® W1.
- Ideal for application on fresh concrete or damp substrates
- Easy, fast and safe to install
- Excellent adhesion to the concrete surface
SikaShield® HB
Torch or self-adhesive hybrid membrane with both an upper layer made of APAO-modified bitumen together with an under layer made of SBS-modified bitumen
- Excellent heat resistance and durability
- Increased elongation
- Improved flexibility in cold conditions
- Excellent resistance to thermo-oxidative aging

Bitumen 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.
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.
Hot Melt Bitumen
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.
