Product Description
Bitumen impregnated boards are made from sugarcane fiber with various percentages of special grade bitumen added. Longer, stronger and more resilient cane fibers allow for better expansion and contraction in filler boards. The boards are made very tough and durable by asphalt, which also lengthens the product’s lifespan. The natural wood fibers chips, and proprietary compounds used to make the impregnated soft board are mechanically reduced to fibers, which are then compressed to form a continuous sheet. During manufacturing, bitumen is integrated into the board to increase its durability and resistance to moisture. The boards are more environmentally friendly than polymeric sheets.
The board’s compression and recovery properties are substantially better than the required averages, according to U.K., U.S., and Indian Standards. Bitumen Expansion Joint Filler has outstanding recovery properties and good compression resistance.
Advantages:
- Durable and simple to use.
- Due to bitumen impregnation, there is less moisture absorption
- It has given concrete the best resistance to the weathering cycle.
- Allow the concrete slabs to move freely during expansion and contraction.
- Simple to cut, dimensionally stable, and neither sticky nor brittle in the summer or winter.
Application:
- Structural expansion joints and structural separation joints in block and in situ concrete construction, such as screed floors, highways, airport runways, pedestrian areas, bridges, curbs, basements, retaining walls, site slabs, subways, and other structures, are filled.
- Filling various kinds of lateral supports, such as abutments and piers, with expansion joints.
- Concrete flooring and other flat works.

Note:
- The boards should be kept in a shaded, cool, dry location. The boards must be packed on a pallet and put on a level surface.
- Keep away from sharp edges and protect the edges from getting damaged. During installation carry single boards vertically.
- When using and storing, caution should be taken to prevent contact with the mouth, eyes, skin, and food. Treat splashes to the skin and eyes right away. If unintentionally consumed, seek emergency medical help. Keep away from children and animals.
