ExCor™ GEOCHEMICAL SOIL ANALYSIS
Geochemical soil analysis is a common method to assess the level of corrosivity to the material type of the asset being inspected.
ExCor™ is Rock Solid Group’s tried and tested analysis methodology and service. Soil sampling can provide valuable insights when there has been evidence via burst history or otherwise of external conditions contributing to wall thinning, graphitic corrosion and cracking.
Soil samples are collected either directly from excavation pit walls or bore holes to the depth and in close proximity to buried pipe assets. The samples are then sealed in air-tight PVC containers for shipping to our preferred accredited soil testing laboratories.
The results of the Geochemical soil sampling can potentially assist to identify the locations along a pipeline where additional data, such as BEM™ scanning should be conducted.
The laboratory output results summarise the following:
A brief description of the key characteristics of the soil
Soil resistivity (natural) (Ωm)
Minimal resistivity (Ωm)
Moisture (%)
pH
Redox potential (mV)
An overview of the soil samples alkalinity, aeration and level of corrosivity to the material type of the asset being inspected.
