The expansion filler is commonly used in buildings where movement is accommodated by expansion joint (in vertical and horizontal joints between units of precast concrete curtain walling, and in construction where it is used as a resilient backfill). It is also used as an anti-vibration pad or non-load transfer filler in both precast and in-situ concrete structures.
