Soil Testing in Construction: Crucial Tests and Their Functions

Soil testing for construction ensures site safety, proper foundation design, and cost efficiency through key tests that assess ground conditions and risks.

Soil testing is a significant process in construction because it is important for absorbing information necessary in determining the foundation and overall layout of any building or infrastructure. For the quality, safety and durability of the works, it is necessary to have a complete soil study made by a serious and qualified design office. The tools required for soil analysis are offered by a variety of businesses, including HEICO, a producer and seller of premium soil testing equipment.

In the construction and development, various types of soil testing methods for construction can be used depending on the specific needs of each project and objective. These include:

Preliminary geotechnical investigation (G1): This gives a preliminary estimate of the geological and geotechnical nature of the site. This step enables the Project Owner to be informed of the possible limitations in regards to the land and properly guide their project.

Environmental diagnosis: It serves to track such risks associated with soil pollution and to suggest corrective/palliative actions, if needed.

Geotechnical investigations: These include sampling of soil to determine its composition, mechanical and hydrological characteristics, and the potential for having groundwater. Two types of surveys exist:

  • Core samplings with material sample (= sample)
  • Pressure meter survey with data collection ( different soil parameter measurements such as resistance, etc. )


Laboratory testing
: This is done in order to evaluate the quality of the soils based on their physical and mechanical properties, such as grain size, plasticity and crush resistance.
