WebJun 17, 2024 · Soakage Tests. Soakage or permeability tests determine the soil infiltration rate and the drainage capacity of the soils or the rate of permeability. There are several methods used to determine whether soil conditions are suitable for soakaway drainage and testing is carried out in accordance with BRE Digest 365. WebSoil texture refers to the proportions of sand (2.0 – 0.05 mm in diameter), silt (0.05 – 0.002 mm), and clay (less than 0.002 mm). The relative proportions determine the textural class. Soil texture influences nearly every aspect of soil use and management. Many of the physical and chemical properties of the soil depend on how fine (clayey ...
