Inward stability, or macro-stability, is a major problem for dikes, in which weak spots can form as a result of traffic load and high water levels. The JLD Dike Stabilizer is an elongated element that is inserted into a dike, at right angles to the potential glide plane, to help prevent the dike from collapsing. The stabilizer consists of an earth anchor and a fin element. The former anchors the system into the compact sand, while the latter provides greater slide resistance.
Final testing of this system is currently taking place at a test site in Purmerend. The method of introducing the stabilizer into the dike is being tested at length, and the technique is already suitable for application. The ENW (Expertise Network for Flood Protection) is expected to endorse the system in the fourth quarter of 2015.
