Understanding Permeability Testing

Permeability testing of soil is a crucial step in geotechnical engineering that assesses how easily fluids, such as water can flow through a given soil sample. This property is fundamental in various construction projects, as it directly influences the design of foundations, drainage systems, and earth-retaining structures.

Darcy’s Law and Coefficient of Permeability

Did you know that the coefficient of permeability is based on Darcy’s Law? Henry Darcy was a French engineer who in 1856 discovered the mathematical relationship that governs the flow of groundwater or the flow of other fluids through permeable or porous materials.

Why Permeability Testing Matters

Accurate permeability data ensures the stability and safety of structures built on or with soil as a foundation. It helps engineers make informed decisions regarding drainage, soil consolidation, and selection of appropriate materials. Whether you're working on a building, dam, highway, or any other construction project, understanding the permeability of the soil is paramount.

Our Expertise in Permeability Testing

At PSL, we pride ourselves on our expertise in conducting thorough triaxial permeability tests. Our team of experienced geotechnical engineers and technicians employ state-of-the-art equipment and techniques to deliver accurate and reliable results.

Modern strength testing in the PSL laboratory

Triaxial Permeability

Our advanced laboratory in Doncaster is equipped to handle a wide range of soil types. At PSL we test permeability by the triaxial method in accordance with industry standards and best practices. Samples are placed into a triaxial cell and encased in a rubber membrane (flexible wall). The cell is then filled with water and once connected to the pressure unit the sample is saturated and pressurised.

Data Analysis and Reporting

Once the tests are completed, we analyse the data and generate detailed reports. Our reports provide clear interpretations of your soil samples. Our team of experts are always available to discuss the results and offer guidance on how to determine the information.
