Geotechnical Exploration in Los Angeles and Orange County


For the highest-quality geotechnical exploration in Southern California, NTS Geotechnical has the perfect services to match your needs. Even before you begin your upcoming construction project, our geotechnical investigations can predict what you might come across while building. As such, you’ll be better equipped to efficiently deal with any problems that arise. Our highly experienced geotechnical engineers have the professional experience necessary to provide you with very accurate results for the makeup of your construction site’s ground, letting you create more accurate recommendations for the foundation needed for your project. 


​At NTS Geotechnical, we understand how complex your site’s subsurface conditions can be, which is why we offer a wide variety of services within our geotechnical exploration in Southern California. Depending on your needs, we can handle tasks including: 


  • Hollow-Stem Auger Drilling: A method of soil sampling that effectively pulls soil cores from the ground after you have drilled to your desired depth. 
  • Cone Penetration Testing: Completed by pushing an instrumented cone into the soil, this test can determine the different layers of soil you’ll encounter the deeper you dig. 
  • Test Pits: These are used to determine the composition of the ground in a certain area, even helping to find the water table. 
  • Hand Auger Drilling: This smaller-scale, hand-powered process is used to take soil samples in a certain area, showing subsurface soil composition. 
  • Bucket Auger Drilling: This larger-scale soil sampling method collects subsurface contents as it drills down, providing you with samples from the area underneath you. 
  • Percolation Testing: Very beneficial for determining the water absorption rate of your soil.
