The Importance of Geotechnical Drilling in Construction Projects

Prior to breaking ground on a construction site, there are many things that need to happen. For instance, it’s important to understand the chemistry and characteristics of the ground on which you’re building. It’s also important to know how solid the ground is and if there’s anything of consequence lying beneath it. The only way to gather this information and have peace of mind going into your construction project is to perform geotechnical drilling.

What is Geotechnical Drilling? 

Geotechnical drilling is the act of drilling small holes, also known as boreholes, into the earth. Geotechnical drilling is a complex process that’s performed by a geotechnical engineer using large-scale drilling equipment known as drill rigs. While the engineer may not perform the actual drilling, they are responsible for overseeing the project and examining the results.  

How Does the Geotechnical Drilling Process Work? 

The geotechnical drilling process is quite interesting. Here’s a quick look at how it works for construction projects. 

  1. A residential or commercial contractor wants to break ground on a new building, parking lot, structure, or another type of project. 
  2. They contact a drilling company capable of performing geotechnical drilling in El Paso and explain their project. 
  3. The drilling company, led by experienced geotechnical drillers and engineers, brings their equipment to the site. 
  4. They then drill a series of boreholes into the ground throughout the construction site. 
  5. These samples of dirt and rock are then preserved and sent to a laboratory for testing. 
  6. The lab will perform an in-depth examination of the samples and report their findings to the drilling company.

Why is Geotechnical Drilling Necessary Before a Construction Project? 

Geotechnical drilling should be standard procedure for any construction project. The purpose of this procedure is to determine the integrity and contents of the soil on which you plan to build. Proceeding with a construction project without understanding the ground on which you’re building is dangerous and irresponsible. 

Because of how important geotechnical drilling is, it’s often required by local building codes and standards. However, even when it isn’t required by code or law, every responsible contractor should invest in geotechnical drilling. Here are some of the things that it can detect. 

  • How loose or compact the soil is 
  • How high the water content of the soil is 
  • How permeable the soil is 
  • The grain size of the soil 
  • How rocky or stony the soil is and what kind of deposits there are 
  • Whether or not there are any potential contaminants in the soil 

How Can Geotechnical Drilling Help You?

Depending on the findings of geotechnical drilling, you may need to alter your construction plans. If the soil is too unstable or hazardous, you won’t be able to build on top of it, and you’ll need to delay or halt your project.

The Science of Geotechnical Drilling in El Paso

When it comes to commercial construction, you know that every step of the process is crucial to the success of a project. Before the building process can even begin, it’s necessary to ensure that the land is suitable for construction by using a technique known as geotechnical drilling. 

In this article, we’ll explore more about this process and show you how the El Paso Drilling team can help provide you with crucial information about your construction site to make your next project a success.

What is Geotechnical Drilling?

Geotechnical drilling is a type of investigative drilling that provides data about soil quality and contents to design and monitor the construction of buildings, dams, bridges, roadways, or other infrastructure sites. This drilling is an important part of the construction process as the information gleaned from these studies helps project managers and engineers determine the supporting characteristics of the soil, which in turn provides insight into the type of materials needed for the project, appropriate depth for installation of pilings, whether or not the angle of the ground will affect building conditions, and more.

Geotechnical Drilling Techniques

When it comes to geotechnical drilling, there are a variety of techniques involved in this delicate process, which is why this part of the construction process should always be left to the professionals. The five types of geotechnical drilling technologies include:

  • Sonic drilling
  • Hollow stem or solid stem auger drilling 
  • Rotary drilling
  • Direct push
  • Coring

Let’s take a look at each of these drilling technologies more closely to see what information each technique can bring to your next construction project.

Sonic Drilling

Sonic drilling is an advanced geotechnical drilling technique that is ideal for deep and shallow drilling applications and can be utilized with any type of soil for nearly any project. This low-impact technique involves the use of specialized equipment that utilizes high-frequency, resonant energy to rotate and vibrate the drill to provide an efficient collection of soil samples while maximizing crew safety.

Auger Drilling

Auger drilling is an eco-friendly, proven geotechnical drilling technology that has a wide range of uses, including soil sampling, installation of data collection instruments, subsurface improvements, and more. This type of drilling involves the use of either hollow stem or solid stem cutter heads that are used to obtain soil samples using split spoon samplers. This type of drilling is the ideal choice for environmental sampling because there are no additives used in the drilling process.

Rotary Drilling

As one of the more basic drilling techniques available, rotary drilling involves the use of a sharp, rotating drill bit coupled that uses impact force to drill through layers of substrate. There are several unique varieties of rotary drilling, which include:

  • Air rotary
  • Mud rotary
  • Dual rotary
  • Reverse circulation rotary

This type of geotechnical drilling is ideal for projects requiring an increased depth as this method is typically more robust than other alternative methods.

Direct Push Drilling

Direct push technology involves the use of a hydraulic hammer to advance the drill through ground layers in an effort to perform soil, groundwater, and vapor surveys or monitor wells. This type of drilling is often used in the collection of multiple samples as direct push drilling can reach deeper depths with a lower impact on the environment than some other types of drilling.

Coring

Diamond core drilling is a technique most commonly used in the mining industry as an approved method for working with cemented or hard rock environments. This technique involves the rotation of diamond-impregnated steel into the ground while applying downward pressure to collect rock core samples for analysis.
