4.2.5 Area with a dense road network

Figure 4.8: Area with a dense road network.

In an area where there is a dense network, the number of roads is large. This means when a
road is flooded or damaged, the distance to alternative routes will not be far. An area will be
cut off from surrounding villages and cities for a relatively short period of time. This will lead to
relatively low indirect costs, but higher direct costs due to the large amount of roads.

By using PowerCem Technology, the direct costs will be low. After the floods, the damage on
the road infrastructure is minimal. This is because after floods on these roads, there is no
damaged, the roads can immediately be opened for use.

With traditional construction techniques the roads will be severely damaged and the
reparation time may take up to a few weeks, in which time the road cannot be used.
