It is rare for any new building or construction project to take place without requiring some kind of excavation. It is even considered symbolic, which is why we often have politicians or dignitaries shovelling the first sod of earth on publicly funded projects for a media opportunity.
Cutting and Filling a Popular Process
However, it takes more than turning a shovel to complete an excavation, or even to know what different types of excavations there are, and how they are used in building and construction. A common excavation process is called cutting and filling, a method used to even out the ground surface, which is now very common when developing housing estates.
In the past, housing estates were largely created by clearing the land as it sat, creating roads and services then constructing homes that suited the natural rises and falls of the land. This allowed homebuilders to take advantage of, for example, hilly terrain, which offered stunning views from the homes they built. Currently, the trend is to cut and fill every natural undulation so that each home sits on a flat lot.
While this process is popular, it does come with some risk, especially where the land is being used for building foundations. Cutting and filling disturbs the natural compaction of the earth so that it then needs to be compacted by machines so that the earth beneath the new buildings does not settle and cause foundations to crack and move.
What is a Pile Hole?
Pile holes or bored piles are excavations typically used for major construction projects. There are several methods used but typically, the soil is removed and replaced with poured concrete to create deep foundations on which the required buildings are constructed. Pile holes can also be used to stabilise slopes to prevent landslides, to secure deep excavation close to existing buildings, and in a variety of infrastructure projects.
Potholing has nothing to do with Shoddy Roads
Another type of excavation is potholing, which is not the same as pile holes. Potholing is excavating a small hole to enable workers to find and inspect underground services such as water and electricity. These small holes are often in areas of high pedestrian traffic and must be covered or barricaded when they are not in use in order to protect people from injury.
