Before you begin any Geotechnical Engineering construction project, it is very important to
perform a site exploration first. But what is geotechnical engineering? And what is geotechnical
investigation? Continue reading this article to know more about them.
Geotechnical engineering technology is basically a branch of civil engineering which focuses on
the engineering behavior of earth materials and geotechnical investigation is the process that
helps engineers in planning the proper design of the structure's foundation. It is very important
to conduct a soil investigation when the ground has never been touched. The factors that are
included in the investigation include the exploration of the depth, rock type, thickness, the
composition of the groundwater and all the characteristics of the soil. To be able to create a safe
design for your structure, you will need to conduct soil testing. Geotechnical Engineering
foundation investigation is necessary to prevent delays that could occur if the soil sampling was
not performed. This also helps keep the construction costs low.

A foundation investigation usually starts with an assessment of the construction site. The
engineers will take a look to see if there are any problems that they can forsee and this can be
done just by looking at the soil's physical appearance.This is what they call surface investigation.
There's a more complex investigation which involves studying the properties of the soil and this
is called a sub-surface investigation. To conduct this investigation, soil sampling, boring, and
testing needs to be done.
In these geotechnical engineering services, boring is the process of drilling a hole on the ground.
To conduct this test, tools like hand augers and rotary drills are important. Soil sampling, on the
other hand is the process of extracting soil from the hole. This then proceeds to classifying them
into one of two categores--disturbed or undisturbed soil. Testing is used to determine the
properties of the soil. Testing for moisture content, liquid limit, sieve analysis, and the like are
done in the laboratory while other types of penetration are executed on the site.

It is very important to keep accurate records from the findings in the soil investigation. This will
be used to create a sturdy foundation for the structure. However, these Geotechnical
Engineering methods may be a bit expensive but they are the best investment as they can
prevent safety hazards. If you choose from the many geotechnical engineering companies and
select the right geotechnical engineering firms to carry out the investigation, it will save you
enough money in the long run.

You need to find a Geotechnical Engineering investigation company that can provide you
excellent work. Many companies out there have websites that can help you understand more
about the services that they are offering. When you have found potential companies, then the
next thing that you need to do is to compare the products and services they are offering. This
will eventually lead you to finding the best company.
