Costly and destructive inspections of dike coverings

The collection of data for monitoring or inspection is costly and/or time consuming.

There is a risk of grit accumulation and cavities in dike coverings made of satiated penetrated quarry stone and poured asphalt. The inspection of grit accumulation and cavities is difficult because they are not visible at the surface. The current inspections exist of core drillings that are destructive to the covering and only provide a limited image. 

The inspection protocol describes how satiated penetrated quarry stone can be inspected using passive microwave radiometry (MIRA). Using this, grit accumulations and cavities can be detected.

• Not damaging to dike coverings
• Less labour intensive than current methods
• Better quality of dike coverings
