Evaluation of corrosion and corrosion protection in soil

RISE test bed offers the opportunity to investigate how different materials corrode in different types of soil under different conditions. Furthermore, the effect of different types of corrosion protection systems can be evaluated.

Our test sites

RISE test sites have been selected to represent some of the more common soil characteristics in Sweden and may be applicable to other countries.

• Ryda, Västra Götalandsregionen
  Type of soil: Clay
  Characteristics: Fine grain size, low organic content, low resistivity, near neutral pH
• Rotsunda, Region Stockholm
  Type of soil: Organic clay
  Characteristics: Fine grain size, some organic content, low resistivity, slightly low pH, brackish water
• Kramfors, Region Västernorrland
  Type of soil: Clay
  Characteristics: Fine grain size, low organic content, low resistivity, near neutral pH, sulphide rich
• Laxå, Region Örebro
  Type of soil: Peat
  Characteristics: Decomposed plants, high organic content, slightly low resistivity, low pH
• Näset, Västra Götalandsregionen
  Type of soil: Organic clay
  Characteristics: Fine grain size, some organic content, low resistivity, neutral to acidic pH, sea water

Each site offers the possibility to expose samples both above and below the ground water level. They also offer the possibility to expose in different types of back-fill.

As soil is a heterogenous and complex medium which can vary greatly not only vertically and horizontally, but also over time, it can be difficult to simulate soil at a laboratory scale. Furthermore, as most of the structures placed in soil are quite large, the heterogeneity of the soil needs to be included in the exposure to give the full picture.

RISE is also looking for new test sites to expand our testing opportunities to new environments.

The test bed offer

RISE test bed gives you access to RISE equipment and our combined expertise. The test bed will give your company answers to questions related to:

• How different materials corrode in soil
• The functionality of different organic and inorganic coatings
• The effect of different back-fills

Please contact us for further information or a quotation for exposure of samples.
