Expansion Joint Filler Board [Compressed Dry Wood Fibers]

Compressed Dry Wood Fiber Structure - The compressed fiber structure provides both mechanical strength and elasticity, allowing the board to compress under pressure while maintaining its dimensional stability.

Bitumen Impregnation - The bitumen treatment improves flexibility and water resistance while protecting the board against microbial growth and environmental degradation.

High Recovery Rate (>80%) - After compression, the board returns to more than 80% of its original thickness, ensuring consistent joint performance even after repeated expansion and contraction cycles.

Low Temperature Flexibility - At lower temperatures, the material retains its flexibility and resists cracking. The molecular structure of the impregnated fibers allows the board to maintain structural integrity even in cold climates.

High Temperature Stability - At elevated temperatures, the bitumen softens slightly but maintains the structural integrity of the board. This allows the filler board to absorb expansion forces without disintegrating or flowing.

1. Roadways & Highways:
   • Installed in roadways and highways, the compressed wood fiber filler board effectively accommodates the expansion and contraction of concrete surfaces due to temperature fluctuations, preventing cracking or displacement.
2. Bridges & Overpasses:
   • Expansion joints in bridge decks and overpasses are subjected to significant movement due to traffic loads and environmental factors. The filler board helps manage this movement, ensuring long-term structural stability.
3. Building Construction:
   • Used in floors, walls, and slabs of commercial, residential, and industrial buildings, where movement due to thermal expansion or settling must be accommodated without compromising the structure.
4. Pavements & Sidewalks:
   • Installed in paved surfaces such as sidewalks, parking lots, and pavements, the filler board ensures a smooth transition over expansion joints while absorbing the pressure from foot traffic or light vehicle loads.
5. Water Retaining Structures:
   • In structures such as dams, reservoirs, and water treatment plants, the filler board helps maintain the integrity of expansion joints, preventing the infiltration of water that could compromise the structure.
6. Industrial Applications:
   • The material is also used in industrial floors, warehouses, and manufacturing facilities where expansion joint movement due to heavy machinery or temperature changes must be absorbed without damaging the surface.

Maruti Expansion Joint Filler Boards are supplied in standard sizes suitable for most construction applications.

Custom sizes and thicknesses may be available upon request depending on project requirements.

Concrete expands and contracts as temperature fluctuates or as loads are applied. Expansion joints are intentionally created gaps in the structure that allow this movement to occur safely.

The filler board is placed within these joints to:

• Absorb compressive forces when the concrete expands
• Maintain separation between adjacent slabs
• Prevent debris and foreign materials from filling the joint space
• Protect concrete edges from damage

When the concrete expands during hot weather or heavy loading, the board compresses. When the structure contracts, the board recovers to its original thickness, maintaining the joint gap.

This continuous compression and recovery cycle protects the structural integrity of the concrete over its service life.
