Figure 5.4: Expected reconstruction time

In figure 5.4 it is shown that a signifacant amount of roads will be blocked for quite a long
period if they are affected by flooding. If these roads can be protected against damage the
nuisance for the environment in the form of the population and industries will be reduced to
the minimum.

Based on this study it can be concluded that the PowerCem technology will have a positive
influence on the macro-economics in flood risk areas. In this study it is shown that a cost
reduction of 50% for the direct costs is not exceptional.

Besides the direct costs, the indirect costs are at least equally important. The indirect costs are
more dependent on the specific situation. The indirect costs in sparse areas are mostly low,
but in an industrial environment these costs can be expected to be extremely high. A poor
accessibility of the road network could even lead to the closure of industries or companies and
employment would be reduced.

However, the macro economic effects will be strongly dependent on the local circumstances
and the country. It will always be advisable to check the local circumstances before a judgment
can be made for the possible savings for companies, entities and governments which are
investing in the road infrastructure of the country.
