This sand still has an angular grain suitable for high constructions. The techniques used originate from the World Sand Sculpting Association. The building of a sand sculpture can be divided into two phases. The first phase is the building phase. The sand is cast into wooden moulds, layer by layer.
Every layer is thoroughly wet and tamped down.
This compacting is done with petrol 'whackers' or with wooden or steel hand compactors. When the wooden mould is full, another mould is placed on top of it, so that a pyramid is shaped with a bottomless dustbin or a drainpipe filled with sand on top. The second phase is the actual shaping of the pile of sand. To carve the sand, the moulds are taken away one by one from top to bottom. The desired shape is than carved in the thus created block of sand and the following mould is taken away.
