Abstract:, A constructional wall element has an outer cladding panel typically a relatively thin and fragile sheet of natural stone and an inner concrete panel which is relatively thicker. The cladding panel is so arranged relative to the inner panel and anchored to the inner panel that the two panels can bow relative to one another, to a bowed position in which one panel is wholly smoothly bowed relative to the other. This reduces the risk of the cladding panel fracturing owing to relative movement between the panels.
