About This Product
Permeability is the rate at which water flows through soil, and it governs seepage, drainage and consolidation. In a falling head test, water flows from a standpipe through a soil sample in a mould, and the fall of the water level over a measured time is used to calculate the coefficient of permeability. The apparatus can also be used with a constant head. Soil mechanics students use it to compare the permeability of different soils. The Permeability Apparatus (Falling Head Permeability) can be supplied for export orders from Mali, Solomon Islands, Poland, Vietnam and Djibouti.
