The formwork is made up of individual elements that can be bolted together in three different ways:

1) The "I" shape is used for straight sections of the wall. (Photo 11)

2) The "L" shape is used for solid, stable corners. (Photo 12)

3) The "T" shape is used for `T´ junctions where partition walls butt external walls, so that the whole building acts as a single structural element. (Photo 13)
