Drilling and Excavation: an Introduction to Foundation Laying

In order for huge buildings to be erected, huge holes must be made in the ground and covered again. This might sound illogical to people, but this a way to make sure that the land that the foundation is going to be laid on is solid. This also a way for the engineers to make sure (aside from sonar and other technology) that the land is not sitting on a tunnel or an old mine. This will make the building ultimately unstable that might lead to disaster and potential lawsuits. This article will give you an insight of the kinds of excavation Melbourne has and what they are used for.

Dredging

Dredging or trenching is the kind of excavation Melbourne and other areas in Australia have that is usually done underwater. It is done so that the bottom sediments can be deposited to another area. This kind of excavation is also a good way to save the dying beaches that have been brought to bad shape by erosion. Dredging is also a good way to get sand and silt for construction if you are short on budget. Just make sure that you got the license to do that. If you are able to do so, go tell the provider on trenching Melbourne has that you’ve chosen as partner.

 Suction excavation

Suction excavation or much commonly known as vacuum excavation is the excavation method that uses a huge vacuum or suction. It is used to remove huge debris of land from the hole that is dug. The suction that is used is an incredible piece of technology. It uses a huge tube (1 food in diameter). The air speed inside the vacuum itself is a whopping 100 meters per second (220 miles per hour). The outer nozzle of the suction pipe has two handles that enables the operator to control the machine. On some designs, the tube nozzles that suck out the debris are toothed so that it can remove the remaining debris a lot easier. This kind of method is available in some excavation Melbourne has today.

Slant drilling

Slant drilling or directional drilling Melbourne companies practice is not a kind of excavation method but it is a critical part of construction especially if the sonar reveals that there is something that needs to be avoided underneath the earth. For example, your construction firm is constructing a sewer and there is an underground facility that needs to be avoided or else you will end up paying for the damage. Slant drilling allows you to bore a hole in the ground while being able to avoid that underground facility.

Slant drilling is also used by oil companies to get their hands on the precious “liquid gold”. Oil deposits, especially on seas, are found under hard layers of rock. Directional drilling allows that excavation Melbourne has to avoid those hard layers of rock and go through the softer spots. This allows to take care and preserve their drills and it also helps protect the environment by not making huge holes out of the ground.
