Foundation Construction On The Sea Bed In The Netherlands

We build wooden houses in many countries. Every country has it’s own exceptions, rules and peculiarities. This time let’s talk about the Netherlands.

We are quite busy building houses in the Netherlands at the moment. Many areas in this country are reclaimed land areas: originally North Sea, but then the Dutch build dikes, pump out the water and build houses on the sea bed. In such areas top layer of ground is very soft and if you build on a regular foundation, your house will sink into the mud.

For this reason, the Dutch have developed a special technique to build foundations in those reclaimed land areas. It is called “paalfundering”. First comes a specialist engineer who does ground tests. They check how deep is the solid ground. If you are lucky it will be at approximately 8-12 meters deep, but in some areas it might be up to 30 meters deep.

When the ground tests are done a big machine comes with concrete poles which will be placed in the ground, until solid ground level is reached. In this photo you can see a concrete pole of 22 meters, which will be placed into ground.

The process of inserting these poles is quite interesting. As you will see in the video below, a concrete pole will be driven into the ground at different speeds, first it will go slower and later will go faster – all depending on the different ground layers.

When all poles are in place we got a solid base to build a foundation on top: place reinforcement, pour concrete and build a slab.
