Foundation survey

When to have a foundation survey?

A foundation investigation is not always necessary. We recommend a foundation study only if there is a risk area (primarily parts of Zaandam, Amsterdam, and Rotterdam) in combination with an indication of foundation defects.

In high-risk areas, there is no sand layer in the soil to build a house on firmly. Therefore, foundation piles are used here and in many other parts of the Netherlands. However, these foundation piles can rot over time under the influence of the groundwater level. Indications of foundation defects include cracks in the facades.

What to do in case of foundation problems?

If problems are expected with the foundation, be sure to indicate this during the building inspection. However, a true analysis of the foundation is not done until a specialized foundation survey.
A foundation survey examines where indications of foundation problems can be found and try to determine their cause. A renovation plan is then drawn up. The full roadmap can be found here.
