What Equipment is Needed to Excavate?


Massive machinery is required to move large chunks of Earth. These machines are specifically designed for excavating. Though, the type of equipment will depend on the type of excavation.

We dug a huge drain to collect stormwater flowing down the hill,it had flowed more than a kilometre from up the street.

For rock excavation, boring machines may be used to drill through large sections of rock and dirt. Explosives are also used to break up larger chunks of stone. For the other types of excavation discussed, an excavator is often used.

What is an excavator? An excavator, which is also sometimes simply referred to as a digger, is a large mechanical shovel. They typically consist of a cab that sits on a rotating platform – called the house. The house is attached to an undercarriage with either tracks or wheels.


From the cab, the operator controls the boom, the dipper, and the bucket. The boom holds the dipper arm, which provides the force needed for digging through the ground. The bucket at the end of the stick scoops large chunks or dirt or other material, which is then dumped into piles nearby.


Without excavation, you would find travel times between cities to be much longer. We can now cut straight through mountains and other obstacles. If it was not for the types of excavation discussed, our world would be very different.


You now know more about the different types of excavation. The next time you see a large excavator along the side of the highway, you will have a general idea of what the person sitting in the cab is up to.


What is an Excavation?


An excavation is essentially any man-made hole in the earth. This can also include depressions in the ground and the removal of just the topsoil. The purpose varies, based on the project that is underway. The main types of excavation include:


  • Topsoil excavation
  • Earth excavation
  • Rock excavation
  • Muck excavation
  • Unclassified excavation


Topsoil Excavation

Topsoil excavation refers to the removal of the top layer of the Earth. Typically, topsoil excavation is used to prepare undeveloped land for construction. All plants and growth are removed during this process. The vegetation is removed, which can be used to make way for other plants and trees.


The soil that is removed during topsoil excavation is often stored. The stockpile of soil is can then be added back to the excavation site. This is done to help control erosion or for landscaping purposes.

Earth Excavation


With Earth excavation, additional layers are removed after the topsoil is excavated. This is necessary for constructing homes, buildings, pools, along with many other construction projects. You will find reasons for Earth excavation in residential, commercial, and industrial development.


During Earth excavation, stones may be uncovered. Any stone that measures larger than ½ a yard squared is considered a rock.


Typically, when a rock is found during Earth excavation, drilling or blasting is required – which is a type of rock excavation.


Rock Excavation


Rock excavation is used to blast through the rock formation and other tough surfaces. Generally, boring and explosives are used to break the stone and remove it in large chunks. For example, you may need to excavate rock in order to build a tunnel through a mountain side.


During Earth or rock excavation, the material is often deposited to nearby lands. It can be used to build an embankment or other man-made formations.

Muck Excavation


Muck excavation is another form of excavation. This refers to the removal of material that contains water or a mixture of soil consistencies. Muck excavation is sometimes necessary for areas with swampy soil or with unfavorable soil composition.


Muck excavation is occasionally used to prepare the soil for other purposes. They may move the muck around a large surface area. This allows the muck to dry, which can remove the water content and allow for other forms of excavation.
