Soil investigation on the dike in Oudendijk and Schardam

What's going to happen?

We have a public duty to ensure water safety in our area. In order to fulfill this duty, we are conducting a monitoring study on various dikes. The purpose of the study is to gather more information about the structure, subsoil, and strength of the dike. This is done in various ways: by drilling in and near the dike, taking soil samples, and installing monitoring wells to measure the groundwater level in the dike. 

The soil investigation has now been completed, and monitoring of the monitoring wells is underway. We are also conducting a bank inspection by a specialized diving team.

Where is the project taking place?

The bank inspection is carried out from the water along the Dorpsweg in Oudendijk. The manual and mechanical drilling took place on and along the storage dykes in Oudendijk (see the red line in the figure below) and Schardam.  

What do you notice?

During the investigation, you may see employees of diving company W. Smit B.V. from Rotterdam in the area. Local residents will receive an information letter about the work to be carried out. The monitoring wells have already been installed in the dike and do not cause any further obstruction to traffic.

When will the project take place and how long will it last?

The diving company will inspect the bank from January 12 to 16. Monitoring will continue until early 2026, and the results of the monitoring and soil investigation will be used to calculate the stability of the dike.

Who do we work with?

The work will be carried out by Arcadis.
