Bitumen Expansion Joint Filler Board 12mm

Construction of concrete roads, runways, floor and roof slabs of buildings, involves casting of concrete in slab form, which leads to construction joints. Provision must be made to accommodate the expansion and contraction at these joints which occurs with seasonal variations in temperature. Our Bitumen Impregnated Expansion Joint Fillers Boards display excellent resistance to compression, with outstanding recovery characteristics. Provision of these boards in the joints permits free movement of the concrete slabs. This prevents damage to the slabs besides providing waterproofing and resisting entry of foreign matter into the joints
