Geotechnical Drilling Safety Harbor What is Vibracoring in Geotechnical Drilling?

Geotechnical drilling professionals do more than simple drill a hole into the ground for further construction on a building or infrastructure project. When it comes to geotechnical drilling, Safety Harbor might not know that some of their jobs require samples to be taken. Often times samples are taken before new construction projects in order to ensure safety on site, and also to further investigate what conditions are like below the surface of the ground. One of the ways of collecting samples is known as vibracore sampling. It is not surprising to think that not many people know what vibracore samples are, how they are obtained, or what kind of information we can learn from them.

Where is Vibracore Sampling Done?

Vibracore sampling is hyper specific, and cannot be used in many areas where normal drilling is sufficient. In geotechnical drilling, Safety Harbor professionals would use Vibracore equipment in areas that are saturated with water, including inland areas like wetlands and lakes. Because of the excess amount of water, many typical drill bits such as rotary drill bits or augur drill bits are not practical, and can often hinder progress and efficiency. Most of the time geotechnical drilling professionals have a hard time determining what sediment conditions are like below the surface of the water. This is another reason why collecting a sample from down below is a great option.

What can Professionals Learn from Vibracore Sampling?

Without drilling into a site on land, geotechnical drilling professionals already have a good idea what sediment conditions are going to be like. Yet when sediment is submerged in a body of water, it is very hard to determine if conditions are more rocky and solid, or loose and sandy. In geotechnical drilling, Safety Harbor residents will have to take a sample of the sediment and look at it without any water. This is known as a core or a core sample that lets professionals see any anomalies that are present.
