Bituminous Expansion Joining Boards

Self-finished bituminous felt made from a carefully selected tough grade of saturated hessian and impregnated with a weather resistant bituminous material. The coating makes the felt rot proof and suitable to use on any surface to render it fully waterproofed. The surface of the felt is dusted with Mica flakes of the right specification to ensure non-sticking and longevity during storage. The felt is wound on cores to facilitate handling. The entire manufacturing process is controlled by strict quality control standards at each stage to ensure that the jute based product is rot proof, fire resistant.

• It preserves the life and evenness of the slab
• It prevents seepage of surface water through the joints and also prevents ingress of water or dirt down the joints
• Permits free movement of the concrete slab
• Absorb ground shocks, caused by vibration and relaxes the stress of the concrete slabs
• Relieves stresses developed due to temperature shrinkage, creep, relaxation, vibration etc.
