Dike reinforcement Kinderdijk Schoonhovenseveer

Dikes are a defining feature of the Dutch landscape, serving not only as flood protection but also as spaces for recreation and conservation. The Lekdijk, part of the Rivierenland Water Board’s jurisdiction, required reinforcement due to weak soil conditions and historical displacements. BESIX was tasked with designing and implementing a solution that would ensure long-term safety while minimizing disruption to nearby homes and the environment. The project combined structural innovation, community engagement, and landscape integration to protect the region from future flooding.

• Reinforcement of the Lekdijk using deep foundation techniques

• Installation of vibration-free bored piles and diaphragm walls

• Integration of deep walls into lower soil layers to prevent water breakthrough

• Phased construction to reduce stress on soft subsoil

• Coordination with local residents and redevelopment of the marina

• Provision for new housing along the dike

• Innovative design: To guarantee safety during high water levels, BESIX integrated bored piles and diaphragm walls deep into the dike’s foundation. If the dike were to fail, the deep wall would still hold back the water.

• Engineering excellence: The design, based on a new application of deep foundation techniques for dike reinforcement, was reviewed and validated by external experts. It passed all evaluations with distinction.

• Minimal impact on homes: Given the proximity of residential areas, BESIX subsidiary Franki Foundations used vibration-free techniques and phased construction to avoid damage to nearby properties.

• Collaborative approach: The project benefited from close cooperation with the Rivierenland Water Board and local design firm Industria, fostering open dialogue and shared problem-solving.

• Internal knowledge growth: The project helped BESIX expand its in-house expertise in dike reinforcement, evolving from a single expert to a specialized team.

• Community engagement: Public support was prioritized through active dialogue with residents. At their request, the project included marina redevelopment and space for new homes, enhancing both safety and habitability.
