Functions and features of elastic liquid bitumen membrane

Liquid bitumen membranes have various applications in construction. They are used in foundations, terraces, and flat-roof waterproofing. Their application is in residential, commercial, and infrastructure construction projects.

Features of elastic liquid bitumen membranes include:

• Elasticity: This is an important feature of liquid membranes. A liquid bitumen membrane can stretch and bend without breaking. This happens even when the building settles or the temperature changes. Elasticity helps membranes stay waterproof for a long time.
• Adhesion: Liquid bitumen creates a strong bond with the surfaces it is applied to. Once the membrane dries, it sticks to the roof, concrete, or metal surface. Good adhesion prevents water from getting under the membrane.
• Seamless finish: Elastic liquid bitumen creates a continuous membrane. This is important in areas with pipes or vents that can cause leaks. The seamless design offers complete waterproof protection.
• Durability: Elastic liquid bitumen membranes last a long time. They resist tearing, punctures, and wear. They can withstand extreme temperatures, UV rays, and chemicals. This makes them great for waterproofing roofs that get a lot of sunlight and heat.
• Easy application: Liquid bitumen membranes are easy to apply. They are applied using brushes, rollers, or spray guns. No special skills are required to use these application tools. This makes liquid membranes a popular choice for waterproofing.
• Customizable: Liquid bitumen is versatile. It can be mixed with other materials to create membranes with different thicknesses and properties. This makes it suitable for waterproofing different surfaces.
• Instant waterproofing: Once an elastic liquid bitumen membrane is applied, it becomes waterproof immediately. This allows work to continue even during rainy days.
• Repairable: Liquid bitumen membranes can be easily repaired. If the membrane gets a small cut or tear, a new liquid bitumen coat can be applied over the damaged area. This helps fix leaks and extends the membrane's lifespan.
