Instant shop front flood wall. It is a segmented wall that fits into existing rebates into the shop front wall and the pavement, thus when fitted and the waterproof seals expanded and locked into place with the support brackets giving a 100 waterproof protection up until the height of the wall. At each end of the shop front a corner piece is inserted and locked and the front segments are then set and locked also with a final aluminium capping to hold the wall fast but bolting it also to the shop front wall. These can be broken down or set up within minutes.
