Geotechnical Survey (Soil Test/Analysis)

brabus

Soil is the most important but often neglected component of a construction project. The soil is the natural foundation that supports all structures and construction activities happening on the land.

Soil Testing/Analysis also called Geotechnical Survey is carried out by Soil Scientist to determine the bearing capacity, chemical characteristics of a soil and suitability of a parcel of land for its intended purpose.

Why should I carry out soil test on my land?

Soil test helps to determine varying physical and chemical characteristic of the soil in a given area, which can vary from place to place and from layer to layer.
Soil test also help determine the bearing capacity of the soil which assists structural engineers to determine the load sustenance capability of the soil and its rate of settlement to make an informed decision during the design of the structure.
Soil testing is also carried out to determine type and adequate foundation depth for the structure being built on the land.
With proper soil information, engineers are guided on suitable construction technique to adopt when building on any type of land.
Soil test also assist engineers in predicting and resolving probable foundation issues.
Soil test is also used to determine the probability of land subsidence and settlement of the imposed load.
Soil test is also used to determine water table in a given built environment and its effect on the foundation.

With requisite information about the soil properties on your land, the structural engineers can efficiently and accurately design the structural elements required to support your proposed development based on the results of the soil test analysis .

Lastly, the result of soil test also help determine whether there is need for soil stabilization and depth of excavation to attain the required bearing capacity.

In the coming days, I’ll be sharing pictures and test reports from a project site in Lekki, Lagos where we’d be carrying out soil investigation to determine bearing capacity and a suitable foundation for our proposed development.

Stay with us.

Site Marking and Grubbing in preparation for soil test.

Site cleared and made ready for geotechnical soil analysis/testing on Monday

Yesterday, successfully out geotechnical soil investigation at our proposed development site.

Test samples collected already sent to the lab for deep analysis. We expect the reports to be ready in coming days.

Finally, after weeks of waiting, the result of the soil test is out and the recommendation of the report is:

Now that we’ve gotten the reports of the geotechnical survey, I think we’re ready to hit the site.

brabus Good morning Brabus… I want to plaster the walls of my 3 bedroom bungalow measuring 39ft by 49ft.. Please what will be the total sqm and how many bags of cement will I need for plastering and later on screeding? Below is the sample design.

Please I need your response, thank you so much.
