Expansion Joint Filler Board

Our Expansion Joint Filler Board is processed from cane fiber, the raw material tested and proven to provide the best resilience. Expansion Joint Filler Board is a perfect base material for expansion joint fillers as it is impregnated with Bitumen in various percentages. The compression and recovery characteristics of the Expansion Joint Filler Board, we offer, confirms to the U.K., U.S.A. and Indian Standards.Expansion Joint Filler Board displays excellent resistance to compression, with outstanding recovery characteristics. These fillers are environment friendly as opposed to the environment destroying thermocole/plastic expansion joint filler. Applications :

• External wall cladding : Filling structural expansion & structural separation joints in block & insitu concrete construction.
• Traffic surfaces : Filling expansion joints in motorways,roads,runways,pedestrian areas, bridges, curbs etc.
• Internal surfaces : Filling expansion joints across concrete floors, including screed floors with underfloor heating.
• Roofs & floor finishes : Ideal for filling expansion joints in concrete floors.
• Building superstructures : Filling expansion joints in basements, retaining walls, site slabs, subways & other water excluding structures.
• Reinforced concrete structures : Expansion joint fillers in piers and lateral supports like abutments.
• Expansion strips : Against existing or between adjacent constructions and insets in concrete paving like drains, manholes, etc. Industrial Flooring
• Internal finishes : Various other flat works and concrete floors according to the state of the art and local regulations.

• Kani Joint Fillers conform to the following required standards
• ASTM -D. 1751-83/D.545 - 84 Testing
• `concrete paving and structural construction'
• `pre-formed expansion Joint Fillers for concrete'
• Department of Transport - London 1986: `specification to highway works, part 3, clause 1015'
• B.S. 1142 for Standard Specifications for Expansion Joint Fillers.
• IS 1838(Part-I) 1983 Standard Test of Expansion Joint Fillers.

• Compression to 50% thickness in the initial state : Recovery is 80/84%
• Weathering and compression to 50% thickness : Recovery is 70/76%. Kani Board returns to more than 70% of its original thickness after three applications of pressure sufficient to reduce its thickness by 50%
• Extrusion : No effect (0.75 mm)
• Uaffected by temperature changes
• Low moisture absorption due to bitumen impregnation. Standard Bitumen content 10-20-35%. Other possibilities upon request.
• Suggested application details for typical joints : Ordinary type. Joint Filler is brought flush with the surface and extends full depth of slab. This is the most common type of application.
• Joint using surface capping. Kani Board Concrete Joint Filler is placed approximately 3/4 of an inch below the surface of the slab. Suitable capping placed flush with concrete surface. Used extensively in highway construction.
• Dowel bar used to preserve alignment of adjacent sections of concrete slab. The joint filler is fabricated to receive dowel bars and the entire joint assembly is placed in position before pouring concrete.
• Joint employing continuous seal either at top or bottom of slab to close joint against hydrostatic pressure.
