Dutch consortia have developed and tested three innovative techniques for reinforcing a dike in a simple manner without making changes to the surrounding area. In the Netherlands the rivers are being given more and more room to avoid having to endlessly strengthen dikes so that they can handle the expected increase in the amount of river water that has to drain away as a result of climate change.
This does not mean that the Netherlands does not do anything to reinforce the dikes along the rivers.
Some solutions: dike stabilising by boring into the ground using a rotating lance to inject a cement mixture. Another method is dike pinning, which involves anchoring the dike to the ground using grout tie bars. The third method uses dike dowels, which are pipes that are installed in the ground and extend down into the Pleistocene layer of sand, which transfer the weight of the dike body to the subsoil.
