Chloride Content:
The effect of chloride concentration in soil on corrosion of reinforcing steel was evaluated by measuring corrosion potentials and corrosion current density.
Concrete in contact with soil bearing high levels of chloride could suffer from early ingress of this chloride, leading to corrosion of any embedded reinforcement. Measures of chloride levels in soils are often taken to check whether the soil will be suitable to be used adjacent to concrete.

Electrical Resistivity:
Electrical resistivity of the soil can be considered as a proxy for the spatial and temporal variability of many other soil physical properties (i.e. structure, water content, or fluid composition). Because the method is non-destructive and very sensitive, it offers a very attractive tool for describing the subsurface properties without digging.
