Call working group on deformations

Following the earlier participation process and associated working groups, a working group on deformations will start this fall (2020). This working group will consist of members of the project team and residents, and where necessary/desired (other) experts and stakeholders will join in. Do you live in Durgerdam and are you interested in participating in this working group? Please let us know via durgerdam@hhnk.nl.

Background information
In Durgerdam, most houses are built on a foundation on steel (without piles). Normally, this type of foundation belongs on sandy soil. In Durgerdam the subsoil consists of (weak) clay and peat soil. It is possible that the house will subside more and more over the years, because the ground under the house is also subsiding. This kind of subsidence is also called autonomous subsidence: this autonomous subsidence can lead to autonomous deformations of the houses that occur without any certain (human) actions preceding it. We see from previous measurements that the autonomous subsidence of some houses is substantial.

In addition to these autonomous deformations, (additional) deformations may occur (relative deformations) as a result of the work. An example of this is work on the dike: dike reinforcement is radical and can affect buildings on and along the dike. Because we want to minimize the chance of inconvenience and damage, it is necessary to look closely at the deformations. We can imagine that you want to be closely involved in this. As with the other themes, a working group will therefore be set up, which you can sign up for.
