The invention provides an improved formwork assembly for erecting a concrete
or other similar
material wall. The assembly includes a plurality of elements to form varying
thicknesses and
varying heights of wall with or without rigid insulation. Each element is
interconnecable to its
counterpart to form two parallel rows of formwork into which the concrete or
other similar
material is poured. The connecting elements have holes in their length to
facilitate the flow of the
concrete or other similar substance and for the placing of reinforcing rod for
initial strength and
stability. The assembly also provides for the construction of corners so that
walls can be joined at
a 90 degree angle on both sides of the parallel rows of elements as well as a
means of replacing
damaged wall elements after construction.
