Bitumen filler board is a compressible, high-density material made of bitumen and fibers. It is available in different thicknesses and densities to suit different types of joints and applications. Bitumen filler board is primarily used as an expansion joint filler in concrete structures, where it provides a flexible, waterproof seal that can accommodate movement due to temperature changes, settling, or seismic activity.

Properties of Bitumen Filler Board

• Compressibility: Bitumen filler board is a compressible material that can be easily compressed or deformed to fill gaps and joints.
• High Density: Bitumen filler board has a high density, which makes it resistant to compression and deformation under the weight of the concrete or other loads.
• Water Resistance: Bitumen filler board is waterproof and can effectively prevent water penetration through the joints.
• Thermal Resistance: Bitumen filler board is resistant to thermal expansion and contraction, making it suitable for use in extreme temperature conditions.

Applications of Bitumen Filler Board

• Expansion Joints: Bitumen filler board is primarily used as an expansion joint filler in concrete structures, including bridges, roads, runways, and buildings.
• Control Joints: Bitumen filler board can also be used as a control joint filler in concrete slabs, where it helps to control cracking caused by shrinkage and other factors.
• Water Retaining Structures: Bitumen filler board can be used in water retaining structures such as dams, reservoirs, and canals to prevent water seepage through the joints.

Advantages of Bitumen Filler Board

• Flexibility: Bitumen filler board is flexible and can accommodate movement due to temperature changes, settling, or seismic activity, preventing damage to the concrete structure.
• Waterproofing: Bitumen filler board is waterproof and can effectively prevent water penetration through the joints.
• Easy to Install: Bitumen filler board is easy to install, requiring no special tools or equipment.
• Durable: Bitumen filler board is resistant to compression, deformation, and deterioration, ensuring long-term performance.
