Leendert de Boers Polder

Validated safe
In the Leendert de Boerspolder south of Haarlemmermeer, the StabiAlert equipment was used to test the strength of clay dykes. 

In 2015, water board Hoogheemraadschap van Rijnland submerged the six-hectares polder to return it to nature. A controlled break of the clay quay offered a unique opportunity to test how dykes respond under extreme circumstances. 

StabiAlert was able to demonstrate the effects of the load. By measuring the vibration and the tilt, the final break of the dyke could be predicted accurately. This field experiment provided an opportunity to test theories about the strength of dykes against reality. This produced valuable new knowledge of dyke loads.
