PERMEABILITY TEST SET - BSO-215 - Image 2

PERMEABILITY TEST SET – BSO-215

The Permeability Test Set is designed to determine the permeability coefficient of fine-grained and coarse-grained soils using both the Constant Head and Falling Head test methods. Manufactured in accordance with ASTM D4647 and BS 1377, the apparatus provides accurate and reliable permeability measurements for geotechnical laboratories and construction quality control.

Standards:

  • BS 1377
  • ASTM 46-47

Soil Permeability Testing

Permeability testing determines the ability of water to flow through soil by measuring its hydraulic conductivity.

The Constant Head Method is typically used for coarse-grained soils with high permeability, such as sands and gravels, while the Falling Head Method is recommended for fine-grained soils, including silts and clays.

Accurate permeability measurements are essential for evaluating drainage characteristics, seepage behavior, groundwater movement, and the engineering performance of soil in civil engineering projects.

Applications

The Permeability Test Set is suitable for:
