Geotechnical analysis Spring Hill Different Forms of Geotechnical Analysis

Geotechnical tests and analysis’ are performed by geotechnical engineers as well as by environmental drilling companies to help them understand the characteristics of soil such as its physical properties that exist underneath a work site. With Geotechnical Analysis, Spring Hill contractors get more than visual analysis from an individual. Usually, when a drilling company is called on for their assistance with soil testing, they will send out those samples to a lab and have them analyzed properly. Soil tests for construction of buildings or any structure is the first step in construction planning to understand the suitability of soil for proposed construction work.

What are Some Types of Geotechnical Testing?

Geotechnical tests usually fall into four categories, test pits, boring, trenching and in-situ testing. Test pits are the easiest type of geotechnical analysis. Spring Hill geotechnical drilling companies will dig a pit either by hand or with a drill in order to reveal the subsurface soil to have an understanding about the land and sediments they are working with. Borings, more often than not small-diameter borings, provide the opportunity to physically remove soil or sediment samples for analysis. Borings provide the advantage of letting you see the actual materials, but for certain types of soils, the very act of boring can disturb the soil conditions and the samples extracted may not represent what the conditions will actually be for building and supporting structures since it is unscientific and void of actionable data.

What About Trenching and In-Situ Testing?

Trenching is very much like that of test pits except that in this case, the pit is elongated over some distance in order to establish how the sub-surface conditions change over various parts of the work site. A range of soil samplers can be used to extract test samples including:

-Shovels
-Hand-driven augers

-Split-spoon samplers

-Modified California samplers

-Shelby tube samplers.

In-situ (in the situation, or at site) testing methods include penetration tests such as Standard Penetration Tests (SPT), which penetrate with drilling, and various Cone Penetration Tests, which penetrate via direct push. These tests measure the physical properties of the subsurface soil directly, without removal. What ever form of Geotechnical analysis, Spring Hill contractors will be able to know exactly what kind of soil they are building a structure on.
