Drilling Holiday Auger Drilling Methods Compared to Air Core Drilling Methods

/in , /by

Believe it or not but when it comes to geotechnical drilling, Holiday drilling professionals have many ways of using their machinery in order to gain access to something underground. Most people think that drilling is simply the process of making a hole in the ground, but the drilling is a much more complex endeavor that requires sophisticated machinery and special methods to do so. Two very common methods used by drilling professionals to gain access to something underground are known as auger drilling and air core drilling. Both methods have the same result of trying to drill deep into the ground, but they achieved in different ways.

Auger Drilling

Many people might not know what auger drilling is, but oftentimes it is the most common method that people associate drilling companies and drilling professionals to perform when drilling. Holiday residents might have used a smaller auger tool in their lawn or garden before to dig up plants or to create a space for new ones, and an auger drilling bit is not much different except for the fact that they are larger and are often made from really strong materials. An auger uses a spiral drill bit in order to drill effectively into many types of soil and sediments as it also clears the debris out of its way.

Air Core Drilling

While auger drilling methods rely heavily on the mechanical and sure force of the drill rig and bit in order to effectively create a hole while drilling, Holiday residents might not be aware that air core drilling uses less mechanical force and more force from pressurized air in order to drill into the ground. While an auger uses a spiral motion to drill into different types of soil and sediments, pressurized air acts more like a hammer driving a drill bit deeper and deeper into the ground. This same air that is used to push a drill bit down very far can also be used to blast small sediments and debris to the surface that can be used for sample collection and analysis.

Environmental Drilling Holiday Is it Hard to Drill into Sand?

/in , /by

The state of Florida is different from many other locations in the United States because the ground and sediment composition are drastically different. In most of the state, the ground sediment that is most common is sand. This is because A Million years ago Florida started slowly rising out of the ocean, leaving behind the sand from the ocean floor. Many people would imagine that drilling through sand would be relatively easy, but this is often not the case when performing environmental drilling. Holiday residents might imagine the hardness of sand is not very high, but this is also what makes it so difficult to drill into with shifting sands.

Drilling Through Sand is More Difficult Depending on the Task

Sometimes drilling through sand is not as hard as it has to be, such as when performing surveys or sample collection because it does not matter too much if the sand shifts into the hole that was dug. One instance where this can be troubling is when someone tries to construct a well on their property. Sand can quickly fill the boring hold that is designed to reach down into the aquifer to give access to water. When performing environmental drilling, Holiday residents should know that drilling through sand can take many hours to make sure a boring hole stays intact.

How do Drilling Professionals get Around Shifting Sands?

It can be very difficult to direct the flow of shifting sands to not affect the drilling task at hand. One way that drilling professionals can do this is by adding water to the location. Drilling through mud can sometimes be easier than drilling through sand with the right equipment used during a task of environmental drilling. Holiday professionals do not want to add too much water to the location that they are drilling because they want the sand mixture to be thick like wet cement or putty. Keep in mind that sand does experience a lot of fluid loss from being so porous, but this can be avoided by adding more water, or sealing of the whole that you are drilling in.

Geotechnical Drilling Holiday Common Signs for Sinkholes Seen by Geotechnical Drilling professionals

/in , /by

Geotechnical drilling professionals have to know a lot about the geology and environment of an era that they will be working in because there are many geological conditions that can change or end a drilling project from ever getting completed on time. When it comes to geotechnical drilling, holiday professionals often see signs of sinkhole activity out at location, and this can drastically affect the task that needs to be done, as well as how are the professionals going to finish their job in the safest manner possible. Here are some common signs of sinkholes that drilling professionals look out for while they are on the job.

Physical Depressions

The easiest sign for drilling professionals to look for out on the job is when a location has a physical depression in the earth, most often sinkholes are going to be round and uniform. Many new professionals mistakenly might think that all changes in a property’s elevation indicates a sinkhole but this is not always true. In order to be sure that a depression is a sinkhole, professionals are going to have to collect samples while performing geotechnical drilling. Holiday residents should be made aware That unless a sinkhole is large enough to open up, it can be very hard to pinpoint sinkhole activity from the surface of the ground.

Cracking in Roads and Buildings

This sign is more applicable to urban areas than rural ones, but another big telling sign that sinkhole activity is present on location while performing geotechnical drilling, Holiday professionals will start to new cracking in structures. This can be hard to tell because as a home gets older, the ground underneath is prone to shifting and settling, which can create cracks that are harmless. It is not harmless when one side of the structure is physically shifting or lowering but the other side is not. Roads and other forms of infrastructure are also susceptible to foundation cracking when there is sinkhole activity underneath the structure.
