Soil classification - UWE

A grading curve is a useful aid to soil description. Grading curves are often included in ground investigation reports. Results of grading tests can be tabulated using geometric properties of the grading curve. These properties are called grading characteristics. First of all, three points are located on the grading curve:

How Do I Ensure Proper Grading Around My Home? - Home ...

If you must add soil from an exterior source, use top soil (sometimes referred to as “blackdirt”) or grading soil. These soils will keep much of the water at grade level until it has a chance to move away (or toward) your house. Do not use sand, because water flows through sand very easily and can turn a bad situation worse.

Soil Classification and Identification (With Diagram)

Coarse grained soil may be described as well graded, poorly graded or gap graded. A soil is said to well grade if it has a good representation of all grain sizes. If the soil grains are approximately of same size, then the sample is described as poorly graded. A soil is said to be gap graded if the intermediate grain sizes are absent.
