Ground investigation on the dike around the Schermer River

What will happen?

We have a public duty to ensure water safety in our area. To fulfill this task, we are conducting a monitoring study on several levees. The purpose of the research is to gather more information about the structure, subsoil and strength of the dike. This is done in various ways: through drilling in and near the dike, taking soil samples and installing monitoring wells to measure the groundwater level in the dike. The company Wiertsema & Partners is a specialist in the field of soil research and performs this research for us.

Where does the project take place?

The probing, drilling, and placement of monitoring wells will take place on and along the regional dike of the Schermer polder (see the red line in the figure to the right). 

What do you notice?

Survey vehicles will be used on the levee during the work. Below are two examples of survey vehicles being used that you may encounter. 

The survey will take place both on and off the embankment. Prior to the field work, the exact locations will be viewed and recorded with a marker or marker posts. You may be asked by the executing party not to place vehicles along the road on the dike on specific days. In order for the investigation to run as smoothly as possible, we would like to kindly ask you to cooperate. The work will not require major traffic detour. However, some of the work will take place next to the road on the verge, which may cause temporary disruption to traffic flow. To announce the work, traffic signs will be placed in the project area, and the temporary work site will be marked out with pylons. 

When will the project take place?

Ground investigation will be conducted in multiple phases. The work will take place in several phases from Monday, March 17, 2025 (week 12) to the end of June 2025 (week 26). 

Who do we work with?

The work is being performed by geotechnical investigation firm Wiertsema & Partners.
