Which type of geotechnical testing is the best for you?
Is there any equipment involved during testing?
Geo-technical tests are performed by professionals or technicians or engineering geologists to determine the characteristics like physical properties that exist underneath a work site. They use geotechnical testing equipments for variety of tests. In this article, we will explain different types of geotechnical testing done by technicians. The list includes-
- Test pits
- In-situ testing
Test pits are exactly what you expect- a pit that is dug either manually or with the excavator machine to reveal the sub-surface conditions to the required depth.
Usually smaller borings offer opportunity to remove soil or rock samples manually for testing purposes. Borings offer the advantage of letting you to see the real materials. But things are different for every type of soil and the act of boring can disturb the condition of soil and samples extracted by you may not represent the actual conditions for building and supporting structures due to its unscientific and void of actionable data.
Usually, soil samples taken from above tests are forwarded to the lab for evaluation purposes.
Trenching is like testing pits. The only difference is that the pit is elongated over some distance to determine how the sub-surface conditions change over many parts of the present site. You can use a range of soil testing equipment to extract test samples, like hand driven augers, shovel, split-spoon, etc.
In Situ testing
In the situation testing methods include penetration tests like Standard Penetration Tests, which are done with penetration through drill, and several Cone Penetration tests, which penetrate through direct push. These tests assist in measuring the physical properties of the subsurface soil without removal. Due to this, technicians are able to generate more precise reflection of conditions underground and avoiding the requirement of sending samples out for lab test.
When the technician understands the types of tests available and the advantages of every test will help the clients to understand CPT advantages through which they can expand their business.
Many geotechnical testing equipments are there in the market today. You just need to contact the right supplier nearby your location.
