Types Of Excavation In Construction

Any project related to construction involves pre-construction stages to ensure that the project remains successful. Whether you are planning to construct a commercial or a residential building, there are some steps you need to do before the actual construction to ensure that the area is able to provide a strong foundation.

Such steps are also involved in building roadways, bridges, installing pipes, or any underground utility. Such pre-steps might include inspecting the land to make it prepared for the next construction.

Excavation is one such method that is an important part of any construction project, and it is done before the actual construction of a building or any infrastructure. Excavation is usually done to remove the material that cannot provide a strong foundation and replace it with the necessary material to prepare the area for the final construction. The excavation process uses different tools to remove the soil rock or other material from a certain area to form a cavity and prepare the area for construction.

Construction companies usually offer excavation and similar services, and a professional company knows that there are different types of excavation in construction. The types of excavation are based on the material and purpose. If you are not familiar with the different types of excavation, this blog post might be of great help. Here, we mention what different types of excavation are carried out for different kinds of construction projects.

Excavation By Material

Such types of excavations focus on the material you need to remove because you would have to use the same different techniques to remove dirt as you would for rock. As a result, based on the material, you will have to use different excavation techniques, which may also require different tools. Continue reading to learn about the different types of excavation used based on the material.

Rock Excavation

Rock excavation is a more difficult task than excavating soil or any other type of material because it has to break up and remove the unyielding rocks. Some rock excavation procedures might also require drilling or blasting to clear the extremely tough rock surfaces on the construction area, especially if you have to construct a basement.

Earth Excavation

Excavation is simply the removal of soil under the topsoil from an area in which you have to construct your project. This type of excavation is quarterly used to create foundations for bridges, buildings, and other infrastructure, as well as installing pipes and underground utilities.

Topsoil Excavation

This type of excavation only removes the topsoil or the uppermost surface area with a depth of no more than 12 inches. This type of excavation removes organic matter, which can cause the soil to compress or make it unsuitable for the construction of a building.

Muck Excavation

This type of excavation is similar to earth excavation, but is a combination of water and soil. It can cause problems on construction sites because the water can make the ground unstable and unsuitable for carrying the weight of any type of building. Therefore, this water and soil combination has to be removed from the construction area and allowed to dry for construction.

Excavation By Purpose

This type of excavation is based on the task or purpose you have to accomplish. For every section process, you may require different types of excavation techniques to ensure that you complete your construction process safely. Continue reading to find out the different types of task-based or proposed excavation types.

Borrow Excavation

This type of excavation actually requires you to add materials, not excavate them away. When this happens, this is called borrow excavation as you are borrowing materials from another location to add to your location. Such materials might include sand, gravel, or any combination of stones that likely come from a pit. Such a type of excavation is necessary to make the construction area ready for construction and to fill or level this area to be used for your purpose of construction.

Bridge Excavation

As the name indicates, this excavation is used for beam or suspension bridges. It helps remove any material that might come in the way of constructing the bridge puttings or abutments. However, such kind of excavation may also require backfilling, like borrow excavation.

Drainage Excavation

This excavation is used to build storm drains or drainage to carry water from an area. This water is carried via a drain, ditch, trench, or similar depression. Moreover, this can also change the flow of agriculture drainage, which reduces the water levels in fields vulnerable to flooding.

Other Types Of Task-Based Excavation

Some other types of task base excavation are channel excavation and dredge excavation. Channel excavation is also used to change the water flow to fight various issues, while dredge excavation removes built-up sediment deposits in waterways.
