After measuring out the polystyrene blocks we'd be using for the main body of the rock pieces, preparation for construction could begin. This included drilling into the polystyrene to begin creating the supports, (left) and using expanding foam to stick two pieces together. This would later on get used for the 'roof' section of the structure, (below).
Stage weights were used to weigh down the piece being stuck down with expanding foam, as as the foam expands, it would begin moving and pushing the top piece off if not adequately weighted. This was left over night to go off.
