Types of Excavation in Construction

Monday, February 18, 2019

Excavation is a general construction term that means to clear away material in order to prepare for an upcoming project. It is a crucial step when preparing to build a new home, business, roadway, bridge or other structures. There are many different types of excavation, each named and classified by the material being excavated for the specific purpose of each project.

Soil Excavations:

Believe it or not, there are a few different types of excavation that involve the removal of soil. These types are: Stripping Excavation, Topsoil Excavation, Earth Excavation, Rock Excavation, and Muck Excavation. Stripping excavation refers to the removal of shallow layers of topsoil, rocks, sand, and other materials. Topsoil excavation involves removing the top layer of vegetation and soil. Earth excavation is the removal of soil below the topsoil layer. Rock excavation is more challenging and involves special equipment, like drilling bits, to remove rock. Lastly, muck excavation is named because its purpose is to remove muck (a combination of soil and water).

Drainage Excavations:

Just as there is more than one type of soil excavation, there are different ways to excavate for drainage as well. They are as follows: Drainage Excavation, Channel Excavation, and Dredge Excavation. Drainage excavation is used when the way water is carried needs to be changed to funnel water away from residential and agricultural areas. Ditches, trenches, and storm drains are good examples of this type of excavation. Similarly, channel excavation removes materials to change the flow of water or increase the capacity of water flow. This type of excavation helps to reduce flooding and water stagnation. Dredge excavation takes place underwater and is used to remove sediment that has built up over time. It allows boats to navigate better without getting stuck.

Excavations used for buildings:

Basement Excavation, Trench Excavation, and Footing Excavation are all used for the installation of new buildings. Basement excavation is used when construction will be (at least partially) below ground level. Trench excavation is a term that means the length of the excavation will exceed the depth. Usually, when pipelines and sewers need to be installed, a trench excavation will be used beforehand to prepare the way. Footing excavation is a foundational structure that helps spread out the weight load of a structure so that it doesn’t sink or collapse.
