Like in any other places, geotechnical testing is also performed by engineers and geologists in Australia to understand the soil properties within a construction site. In essence, this type of investigation plays a crucial role in ensuring structural safety and preventing damage caused by a poor foundation, ground movements, and catastrophes, like earthquakes. To understand how it can help with your project in particular, it is best to know how it is used on your site.
- Creating Test Pits
This method involves digging pits to a specific depth to determine the conditions underneath the surface of your work site. Through these pits, you will be able to gather samples of earth and study its structure and composition. Also, you will be able to learn more about the geology and water table of your site. All in all, these pieces of information are essential before you start any groundwork.
- In-Site Testing
Another way that geotechnical testing Australia has is applied to your project is using dynamic penetration tests, such as the Standard Penetration Test (SPT). In this method, specialised equipment is used to drill the ground via direct push to measure the physical properties of the ground you are building on without having to remove earth. It generates a more accurate reflection of sub-surface conditions without sending samples to a laboratory. For these reasons, it is a top option for those who want to break ground at the soonest possible time.
- Soil Boring
Like test pits, this method also requires digging, but you only bore holes in smaller diameters. It allows you to physically remove the actual materials—soil and rock—and test them for permeability and support, so you will know whether or not the ground will be able to hold up structures without building piers, footings, and other structural aids. However, the act of boring can tamper the original conditions underneath the ground, so you need to send the samples to a laboratory for further testing.
This type of Australian geotechnical testing involves digging elongated pits over a distance to identify how your work site’s sub-surface conditions change over a range of areas. In particular, this is done to locate slide planes and faults.
To get a rough idea of the underlying soil conditions of your site, engineers would drive steel bars into the ground until it reaches a hard stratum. Then, the bars will be drawn out at intervals. Now, the soil sticking to the bars at these points will be collected and examined to determine its characteristics. Ground conditions are also determined by observing the way the bars penetrate into the soil.
Depending on your situation, you can use any of the above-mentioned methods for your work site. By doing so, you will gain topographic information that is important in the ground-breaking and completion of your project. You can ensure that there will be no problems related to its foundation that can put you and your workers at risk.
