Inspection Revetment IMG20151002NCDR International BV has been involved in the investigation and remediation design study of a Port Basin revetment in South-east Asia. After construction of revetment works some initial, unexpected settlements of the armour layer occurred which may endanger the stability of the revetment over time.
A site visit was performed including high detailed survey of the facing above and below water by drone and bathymetric survey. The bathymetric survey was done by a dual Multibeam system, providing high detail data and highly accurate image of the armour facing below water level.
Based on the investigation study, including review of design, construction and supervision, a physical modelling study is performed to obtain the most practical, reliable and cost-efficient remediation design. Attention is paid on the execution aspect of the design to minimize further negative effects.
