Geotechnical soil survey — is it worth it?

Building your own home is a dream for many of us. It is worth remembering, however, that it is not only an exciting process but also one that requires proper preparation and knowledge. One of the key elements that can decide the success of the investment is the geotechnical soil survey. In this article we look at the topic and explain why it is worth investing in this procedure.

What is a geotechnical soil survey?

A geotechnical soil survey is a process aimed at understanding the properties of the ground on which we plan to build our home. It is a key step, because the type of soil and its bearing capacity can affect the design of the foundations and the stability of the entire structure.

The procedure involves drilling and probing on the plot, as well as taking soil and water samples that are analysed in a laboratory. Geotechnical surveys make it possible to determine the type of soil, its bearing capacity, the groundwater level and other important parameters that are crucial when designing the building.

Are geotechnical surveys mandatory?

A common question is whether geotechnical surveys are mandatory before construction begins. The answer is not clear-cut and depends on several factors. In the vast majority of cases, for single-family houses, these surveys are not mandatory by law.

Cost and time of geotechnical surveys

The cost of geotechnical surveys can vary and depends on many factors, such as the location of the plot, the scope of services and the depth of the boreholes. Typically the price of a geotechnical survey for building a house ranges from PLN 1,200 to PLN 1,900.

Summary

A geotechnical soil survey is an important step before building a house. Although it is not always mandatory by law, it is worth investing in this procedure to avoid problems related to unsuitable ground conditions. Thanks to a geotechnical survey you can adapt the building design, choose suitable foundations and minimise the risk of structural damage. It is an investment that can bring large savings and provide certainty about the durability and stability of your future home.
