Unstable peat dike

An increased flood hazard because the flood defence does not meet the requirements and/or due to extreme conditions.

Because of a thick layer of asphalt that is put on top of the Jisperdike, the dike no longer meets the norms for stability. There is limited space available for its reinforcement.

The quay improvement of the Jisperdike combines the following three techniques: soil reinforcement of the ditch at the foot of the dike, the placing of a carbon fiber seepage screen and the placing of a new road construction. This combination of techniques allows for the dike to be reinforced within its current profile, producing less nuisance for the direct environment while creating more height.

• Reinforcement of the dike within the current profile
• Less chance that the dike will slide off and fail
• No extra land purchases needed
