Our Story


The dykes in the Netherlands are regularly tested on safety and dyke reinforcement has been or will be implemented with regard to many dykes (first and second test rounds). These improvements have taken place within the context of the national high-water protection programmes HWBP and HWBP2 (HWBP is the abbreviation for the Dutch term “HoogWaterBeschermingsProgramma; i.e. high-water protection programme).

Now, the third testing round has been completed and the rejected dyke areas that resulted from this are being improved within the context of the New High-water Protection Programme (nHWBP). The Netherlands has approximately 3,767 kilometres of dunes and dykes that are earmarked by the Dutch Water Act as primary water defences. Approximately 1,225 kilometres does not meet the prescribed safety standard, approximately 1,225 kilometres does meet them and approximately 234 kilometres requires further investigation.

JLD Dyke Stabiliser – faster, smarter and cheaper


The High-water Protection Programme (HWBP) has the goal of reinforcing all primary water defences that currently do not meet the set standards.

The HWBP is set to reinforce more than 730 km in primary water defences during the coming years. Four project-surpassing surveys are also being started as part of the programme (Piping, Wadden Sea, Central Netherlands and Macro-stability) where the most important HWBP objectives are that it must all happen faster, smarter and cheaper!

Innovative solutions


One of the ways in which these programme objectives can be realised is to promote and develop innovative solutions for the programme remit. Innovation budgets are available to ensure that innovations end up being projects where tests such as that of the JLD Dyke Stabiliser can be included.

The JLD Dyke Stabiliser test is part of the project-surpassing Macro-stability survey and provides the details for the HWBP preference to embed innovation in the programme.

The Rivierenland Water Board has been prepared to jointly perform this test to meet the criteria for the project-surpassing surveys.
