Blocks are normally delivered to site in banded packs oncrane-offload road vehicles. Where requested packs can be delivered shrink-wrapped and/or palletised to aid subsequent site movement activities. All packaging should be disposed of carefully in accordance with local environmental requirements.If possible, delivered blocks should be stacked in plannedlocationson the site. This reduces the double-handling of the blocks.Packs should be stacked carefully onto a prepared, clean,firm area to minimise soiling and damage. They should also be protected from inclement weather and passing vehicles....
