Bitumen Membranes

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
