What is Bituminous Membrane? Usage Areas and Advantages

Bituminous membrane is a material widely used in roofing and waterproofing projects. This membrane is bitumen-based and was developed to provide waterproofing, durability and longevity. Bituminous membranes, which offer different advantages compared to other waterproofing solutions such as PVC membranes, are preferred in various application areas.

What is Bituminous Membrane?
Bituminous membrane is a bitumen (asphalt) based waterproofing material. It is usually reinforced with carrier materials such as glass fiber or polyester felt and its two surfaces are coated with a polymer-bitumen mixture. This structure increases the waterproofing and mechanical durability properties of the bituminous membrane.

Bituminous Membrane Usage Areas
Roofs:
Bituminous membrane is used to provide waterproofing, especially on flat and low-slope roofs. It is preferred in roof applications such as PVC membrane.

Terraces:
Bitumen membrane is ideal for waterproofing and protecting terraces. It may be more economical compared to PVC membrane alternatives.

Fundamentals:
Bituminous membrane is used for waterproofing of building foundations. This prevents water from penetrating the foundation structures and extends the life of the structure.

Basements:
Bitumen membrane is also preferred for waterproofing basement floors. It prevents water leaks and keeps the interior dry.

Bridges and Highways:
Bituminous membrane is used to provide waterproofing on bridges and highway surfaces. This application prevents structures from being damaged by water and moisture.

Bituminous Membrane Advantages
Durability:
Bituminous membrane shows high resistance to environmental influences. It is resistant to UV rays, ozone and chemicals.

Waterproof:
Bituminous membrane provides effective waterproofing on roofs and other surfaces with its waterproof feature.

Flexibility and Strength:
Bituminous membrane reduces the risk of cracking and breaking thanks to its flexible structure. It also has high mechanical strength.

Easy Application:
Bituminous membrane can be easily applied to different surfaces. During application, hot air or flame bonding method is generally used.

Economic:
Bituminous membrane is an economical solution for waterproofing. It can provide a cost advantage compared to other solutions such as PVC membrane.

Fire Resistance:
Bituminous membrane is fire resistant and does not catch fire in case of fire and does not spread combustion.

Technicial Specifications
Thickness:
Bituminous membrane is generally produced in thicknesses ranging from 3 mm to 5 mm.

Colour options:
Available in black and grey. Its surface is often reinforced with mineral coatings.

Temperature Resistance:
The bituminous membrane performs in a wide temperature range from -10°C to +80°C.

Conclusion
Bituminous membrane is a material that stands out with its durability and economy in waterproofing and roofing projects. It offers different advantages compared to alternatives such as PVC membrane and provides effective results in various application areas. Bituminous membrane is widely preferred in the construction industry with its durability, waterproofness, flexibility and economy. Long-lasting and reliable waterproofing solutions can be achieved with the right material selection and professional application.
