Corrosion in soil
Much of society's vital infrastructure is in the ground and is therefore exposed to soil corrosivity. These structures include water and sewage systems, natural-gas pipelines, cisterns for oil and fuel, telecommunication cables, pylon foundations for power transmission towers, culverts, etc. Here, corrosion can have disastrous consequences.
Corrosion in soils is mainly dependent on moisture content, oxygen availability, chemical composition/mineral content, redox potential, pH, resistivity and microbial activity. Soil composition varies both vertically and horizontally and is heavily influenced by excavation and seasonal variations.
Swerea has more than 40 years of experience in assessing corrosion risks, lifecycles and corrosion preventive measures in soil.
