In many circumstances steel corrosion rates are low and the use of protective methods is not necessary.
The walls are often used to retain either soil or water.
The key advantage of amlocor is a significant reduction of the corrosion rates in the low water zone lwz and in the permanent immersion zone piz which is normally the location of the maximum bending moments and consequently the location of the highest steel stresses.
