A soil investigation is the very first step if you’re planning to build.  Still waiting for your building permit? No problem. You can already have your soil investigation carried out. It will give you highly valuable information about your plot.First the soil investigation. Then the design.Have you bought building land? Have the soil investigation carried out first. And pass the results on to your architect. Based on the findings of the soil investigation, your architect can adapt the design to your building site. Many architects already work with us in exactly this way: first the soil investigation. Then the design.Or do you prefer to wait until your building permit is approved?  That is a possibility too. However, test results may sometimes show that the soil is not suitable for the design. Unless you invest in much more expensive foundations than planned. Ordering the investigation later may therefore affect both your budget and your schedule.With a soil investigation, you can estimate your budget more accurately in advance. In doing so, you may avoid unexpected extra costs during construction.With a soil investigation, you can determine the necessary foundations in advance. Any additional foundation works will always delay the planning.

Accepted Answer

There are three good reasons to perform a soil investigation.You’ll know exactly which foundations are needed. Even in ‘weak’ soil.You avoid unexpected extra costs during construction.You won’t overpay for your building land.Have you bought building land? Congratulations! But sometimes the soil turns out not to be very load-bearing. People often call this “weak” or “poor” ground.  Soil that is rather unsuitable to build on. That’s exactly why a soil investigation is so useful. It tells you precisely how strong (or weak) your building land is. And it advises which foundations are required to make sure your house will stand firm for generations.Yes, you can build on ‘weak’ soil Provided that you have the right foundations.It is perfectly possible to build on “weak stuff”. On the condition that you build on the right type of foundations.  This will be decided by your architect, based on the results of the geotechnical or soil investigation.  Such a test reveals the load-bearing capacity of your building land.  That way, you avoid cracks, damage, or even subsidence of your house.You estimate your construction budget more accuratelyA soil investigation allows you to estimate your budget more accurately in advance.  The geotechnical or stability investigation advises you which type of foundations are required for your building land.

Question 3

How many cone penetration tests should I have carried out?

Accepted Answer

A standard soil investigation consists of at least 3 cone penetration tests (CPTs). We perform these tests at different locations on your building land, so you get a complete picture of the bearing capacity of your land.Three CPTs at different points on your building land actually give you a solid overview of possible variations in the different geological layers.For larger buildings, such as apartment blocks or industrial buildings, the Belgian Building Research Institute (BBRI) recommends one CPT per 300 m².Sometimes, during the investigation, it becomes clear that more than three cone penetration tests are required. In that case, our experienced technicians will contact you right away.Any questions? Request a quote? Order? Do not hesitate to contact us.
