The Soil Permeability Apparatus is a highly reliable setup used to determine the permeability (coefficient of permeability) of soil, particularly in clay, silt, and sandy materials. It helps evaluate water flow characteristics through soil, which is crucial for geotechnical design, groundwater studies, dam engineering, and foundation stability assessments.

This apparatus is available in both Constant Head and Falling Head configurations for a wide range of soil types. Sturdy glass or acrylic cylinders, precision valves, and accurate measuring scales ensure consistent results with high repeatability. Designed for laboratory usage, the unit complies with major geotechnical testing standards to support accurate project evaluation.

Compact, durable, and easy to operate, the Soil Permeability Apparatus is an essential instrument for geotechnical engineering labs and construction quality control testing.
