Excavation by definition refers to the action of moving earth, rock or other materials with equipment or explosives. Because there are different types of excavation based upon the purpose or type of material being excavated, we thought we’d give you an overview of a few different types and what they are intended to be used for.
- Bridge – This is essentially just what it sounds like, removing material in the anticipation of building a bridge and ensuring that it is supported by the foundation on which it will be constructed.
- Borrow – Unlike many other types of excavation where material is removed in order to complete a construction project, borrow refers to adding additional material from another site for grading or filling purposes.
- Channel – Typically this is used to change the flow of water or increase the capacity of an already existing waterway. Many times this is done to protect from flooding issues or to eliminate sediment buildup which can create problems down the road.
- Dredge – Similar to channel excavation, sentiment buildup can cause serious issues if not dealt with on a regular basis. Waterways may become impassable leading to other issues such as boats being stuck or wildlife losing habitat.
- Footing – Just as it sounds, footing creates structural support for bridges, buildings and other structures by evening the weight load of these heavy structures and preventing sinking or collapse. This is typically done once a construction site has been properly graded and is ready for footings to be concreated in to place.
- Roadway – Everyone has witnessed a road being built but many don’t understand that undertaking these projects can be very difficult at times. Material may be needed to fix unsuitable slopes which may combine borrow excavation practices by bringing in additional material to help level the embankments.
- Stripping – This typically involves less digging and more clearing of large areas and material such as gravel, sand, rocks and topsoil so that grading can be completed for a construction site.
- Topsoil – Similar to stripping, but referring to more of a vegetation clearing of an area, focusing on the top layers of the ground being cleared.
- Underground – Specific equipment and techniques are used to create underground clearings for things like subways, canals and sewage all of which take additional time and effort for safety and durability of the dig site.
Ultimately, excavation can cover a wide range of projects all which lead to the ability to either stabilize something or build something with a focus on safety, sustainability and accessibility. Excavation, especially on large projects should be conducted by experienced professionals and done with safety and the longevity of the project in mind.
