About Bitumen-Impregnated Bagasse Board (Elastic Filler Board)

Bitumen-impregnated bagasse board, also known as elastic filler board, is a construction material made from sugarcane bagasse fiber, a by-product of sugar production. The fiber is pressed into sheets and then impregnated with tar or asphalt (bitumen) to improve water resistance, durability and flexibility. It is designed for a variety of construction uses, particularly as a roof underlay or a waterproofing layer for structures, protecting against moisture and water penetration and helping extend the service life of buildings and structures.

Composition and Manufacturing

Production starts by processing sugarcane bagasse into fiber, which is then pressed into board with the right density and structure. The key step is impregnating the board with tar or asphalt, a compound with good water-resistant properties. This coats the bagasse fibers in a layer of bitumen, giving the board excellent water resistance, high flexibility and durability in changing weather. Using bagasse is also a sustainable choice, since it is an agricultural by-product.

Key Properties of Elastic Filler Board

• Water resistance: Its most important property is effective resistance to water and moisture, preventing water from seeping into the structure.
• Flexibility: The board is highly flexible, so it conforms to different shapes and is less likely to tear when the structure moves.
• Durability: It withstands temperature changes and varied environmental conditions, making it suitable for exterior use.
• Insulation: It provides some degree of heat and sound insulation, helping improve a building's energy efficiency.

Applications in Construction

Bitumen-impregnated bagasse board plays an important role in many types of construction, including:

• Roof underlay: Used as an underlayment beneath roof tiles to stop rainwater from leaking through if tiles are damaged, and to keep out outside moisture.
• Waterproofing for walls and floors: Used as a moisture barrier for walls or floors in areas that need extra moisture protection.
• Underlay for roads and walkways: Used as a base layer to help extend the service life of roads and walkways.
• Underlay for floor leveling: Laid before pouring concrete or leveling a floor to prevent ground moisture from rising into the structure.

Types and Specifications

Bitumen-impregnated bagasse board is available in several sizes and thicknesses for different applications. For example, the 4x7 ft size is widely used for general work. The right choice depends on the project's waterproofing and durability requirements.

Buying Tips and Price

When buying bitumen-impregnated bagasse board, consider thickness, size and water resistance to suit the type of construction work.
