Limmel flood barrier

New flood barrier protects the Limburg hinterland

BESIX, in collaboration with BESIX Unitec (formerly known as Agidens Infra Automation) and Rebel Group, successfully delivered the Limmel Flood Barrier project for Rijkswaterstaat. The project involved the design, construction, financing, and long-term maintenance of a new flood barrier on the Juliana Canal near Maastricht. The barrier enhances flood protection, improves navigability for large vessels, and integrates sustainable, low-maintenance technology.

Project overview

The Limmel flood barrier, originally built over 80 years ago, was a critical link in the Maas Route, connecting Belgium, the Netherlands, Germany, and France. BESIX was entrusted with the replacement of the outdated structure to meet modern safety and navigation standards. The new barrier not only protects the Juliana Canal and surrounding areas from flooding but also accommodates larger cargo vessels and improves safety for cyclists and pedestrians.

Scope of works

Design and construction of the new flood barrier
Demolition of the existing flood gate
Installation of a hydraulic lifting mechanism
Construction of a new bridge with separate lanes for cars and cyclists
Maintenance of the flood barrier infrastructure
Coordination of project financing and stakeholder engagement

Highlights

Innovative engineering: BESIX and BESIX Unitec designed a simple yet robust hydraulic lifting mechanism activated by the weight of the gates, minimizing electronics and maintenance needs.
Watertight design: The dam walls were anchored into the limestone bedrock on all four sides, creating a sealed, watertight structure.
Minimal disruption: BESIX ensured that the Juliana Canal remained operational throughout the works, with only four planned closures of 24 hours each.
Smart phasing: The new lock was built before the old one was demolished, maintaining flood protection and uninterrupted freight traffic.
Community engagement: BESIX prioritized dialogue with local residents, integrating their feedback into the project. The redevelopment included a safer bridge and marina improvements.
Educational innovation: BESIX developed Limmel the Game, an educational tool for secondary school students to simulate stakeholder collaboration in infrastructure projects.
Sustainable collaboration: The integrated contract model allowed BESIX to manage design, construction, and maintenance, fostering efficiency and long-term learning.
