Bitumen Waterproofing

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.

Bitumen technology dominates approximately

60%

of the flat roof market worldwide.

Bituminous membranes are waterproofed and highly

customizable

to meet specific requirements due to the combination of different materials they can be made of.

In some countries, bitumen accounts for over

80%

of the flat roof market.

Sika offers the best bitumen solutions, thanks to our

worldwide

experience and strong know-how in bitumen, waterproofing and roofing technologies.

Once applied, torch-on bitumen 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

General Bituminous Membrane Build-Up

The combination of raw materials can be built up in thousands of possibilities, but this is a typical composition example.

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.
