Soil permeability, in terms of a permeability coefficient (k), measures a soil’s ability to allow water to pass through it. Soils are permeable materials due to their grain structure and the existence of interconnected voids. A good knowledge of soil permeability is important for both civil engineering and agricultural purposes. Although determining a sample’s permeability can require many steps, the process can often be simplified with the proper tools.

M&L Testing Equipment’s Soil Permeameters are used to determine the coefficient of permeability in both constant head and falling head test methods.
