Testing and Classification of Soil in Excavation Services

Soil is an essential and inseparable part of the excavation. It is an important aspect that contributes towards conducting and finishing the excavation project successfully. And, that’s why excavation companies do extensive soil testing, prior to starting the excavation. Here, we will discuss various types of soil testing.

Type A

It is the most stable and cohesive soil type that has released compressive power. The soil type is usually rich in several clay types such as slit clay, sand clay, and clay loam. The specific type never has fissured soil (soil which is disturbed or has a water flow through it).

Type B

It is generally less stable but a cohesive soil type. This soil is not as sticky as the first variety and also doesn’t have a definite compressive power. Its examples are silt, silt loam, angular gravel, and soil close to the source of fissure or vibration.

Type C

Sand and gravel are discovered in abundance and are covered under type C soil. It is an unstable soil form due to the lack of firmness. Any soil type which has water leaking through it is categorized under this type.

Things to check before performing a soil test

  • Is the clumsy or granular?
  • Is it fissured, or has some cracks or other openings?
  • Any source of huge vibrations close to the excavation site?
  • Keep an eye for signs of soil being disturbed by some sources such as utility lines
  • Look out for signs of water seepage via the soil at the site of excavation

In addition, working with reputed earthmoving equipment hire in Brisbane ensures they perform other tests such as plasticity test, thumb penetration test and pocket Penetrometer test as well.
