OXIBOARD BI 20 is compressible bitumen impregnated soft board expansion joint filler. The impregnated soft board is made from wood chips and wood waste, mechanically reduced to fibers which are then pressed to form a continuous sheet which is then cut to size. Bitumen is incorporated into the board during manufacture to improve its moisture resistance, damp resistance and durability.
Ideal to form movement joints in in-situ concrete, construction joints in precast concrete construction. Structural expansion joints in concrete slabs, basements, retaining walls and other concrete wall construction. Protection of waterproofing membrane from mechanical abuse and against backfill.
