Holland already has a standard
prefabricated system which can be
taken down and rebuilt. In Denmark
and Sweden there are many exam-
ples of industrial units and agricul-
tural buildings built out of almost
entirely recycled concrete units.
Figure 13.5 shows a Norwegian
foundation system in concrete units.
All the components are standard-
ized and locked together internally
with grooves or bolts. During demo-
lition, the ties and pillars are lifted
Figure 13.3: Examples of blocks which do not need mortar. Their
measurements are very exact, with a height difference of a
maximum of ±1 mm. They are usually tongued and grooved.
Their re-usability depends upon the strength of the render used
on them. This method of building should reduce the amount of
labour by about 30 per cent.
