Fundamental research: Don't build blindly – this is your most important investment

What do building a house and sailing have in common? You shouldn't go on either trip without a map. In construction, this map is the foundation study, i.e. soil research It is a critical step that reveals what lies beneath the topsoil: whether it is load-bearing gravel, soft clay, or hard rock. Neglecting this information is one of the most costly mistakes a builder can make.

Based on the results of the soil survey, the structural engineer determines what kind of foundations your house needs. Without reliable information about the bearing capacity of the soil, foundations have to be designed based on guesswork, which almost always leads to either oversized and expensive solutions or, at worst, undersized and risky solutions. A soil survey is not an expense, but an investment that can save you tens of thousands of euros in unexpected costs during the foundation phase. It gives you peace of mind and the certainty that your home is being built on a sustainable foundation.

• A soil survey is a prerequisite for a building permit and a necessary measure to determine the bearing capacity of the soil on the plot.
• It determines the correct and safe foundation method for your house (e.g., soil-based or pile foundation).
• A ground survey conducted by a professional costs around 1,200–2,500 euros, but can save tens of thousands of euros in unexpected foundation and earthmoving costs.
• The final result of the study is an official foundation study report, which is the basis for structural design.
• A soil survey is a critical step in minimizing risks, and it is worth having it done before purchasing a plot of land.
