What is a geotechnical investigation?
It is the process of studying the ground and rock below a site to understand its properties. This helps us ensure that your new building, bridge, or road is built on a safe and stable foundation.
Can you work on land and in the water?
Yes, we have a diverse fleet of over 65 drilling rigs and specialized floating equipment that allows us to perform investigations both on land and in bodies of water like rivers and oceans.
How deep can you drill?
We have drilling rigs capable of reaching great depths, with some of our big rigs able to go as deep as 240 meters, ensuring we can gather data for any project.
What happens to the soil and rock samples you collect?
We take them to our certified laboratory where we perform many different tests to measure their strength, density, and other important characteristics.
Do you have a certified lab?
Yes, our laboratory is accredited, which means our testing methods and results are reliable and meet the highest national standards for quality.
Can you do lab testing at my project site?
Yes, if the project requires it, we can set up a mobile or satellite laboratory right on-site to provide quick and convenient testing services.
Why do you test piles?
We test piles to make sure they are strong enough to support a structure and that they don't have any hidden defects, ensuring the foundation is safe and secure.
How can you check a pile without digging it up?
We use special tests, like a Pile Integrity Test (PIT) or a Cross-Hole Sonic Logging (CSL) test, which use sound waves to check the pile's condition and quality.
Can you find what's buried underground without digging?
Yes, we use advanced tools like Ground Penetrating Radar (GPR) to create images of what's below the surface. This helps us find pipes, cables, voids, or other hidden objects.
How do you check a road's condition?
We use a special vehicle called a Falling Weight Deflectometer (FWD) to precisely measure the strength and stiffness of the pavement, helping determine how durable the road is.
What is a seismic survey?
It is a way to measure how sound waves travel through the ground. We use this to understand the different layers below the surface and determine the depth to bedrock.
How do you know how strong the ground is?
We perform on-site field tests like the Plate Load Test or Cone Penetration Test (CPT) to directly measure the ground's ability to support a building or foundation.
Do you check if the ground is compacted correctly?
Yes, we use methods like the Field Density Test or Nuclear Density Test to measure if the soil has been compacted to the right density for a project.
What does a Pull-out Test do?
This test measures how much force a pile or anchor can resist before being pulled out of the ground. It is an important check for stability, especially for towers and other structures.
How do you verify the quality of concrete?
We use a non-destructive method called Ultrasonic Pulse Velocity, which uses sound waves to check the quality of concrete in beams, columns, or other structures without causing any damage.
How do you analyze all the data you collect?
We use a suite of modern, powerful computer programs to analyze and process all the data from our drilling, lab, and field work, creating detailed reports for our clients.
Can you assess the stability of a slope?
Yes, we use specialized software to analyze data and determine if a slope is stable, helping to prevent landslides and other failures on your site.
Do you provide reports?
Yes, our data processing and management software ensures that all the information we gather is compiled into clear, comprehensive reports for you.
Do you offer services for offshore projects?
Yes, we have specialized equipment and methods, like our offshore MASW survey, to assess material layers and detect anomalies in underwater environments.
What is a Geo-resistivity test?
This test uses electrical measurements on the ground's surface to determine the depth of soil layers and find the groundwater level, which is useful for things like well installation.
