Friday, November 13, 2015 — Lanaye, November 13th, 2015. Since June 2011 BESIX has been executing the construction of the 4th lock in Lanaye and its related works. Today the project is inaugurated by his highness King Philippe. The Lanaye complex is a strategic crossroad for water traffic: straddling on Belgium and the Netherlands, it is the  mandatory crossover point between the Belgian, French, Dutch, German and central European waterway networks.

The 4th lock in Lanaye is 225 meters long and 25 meters wide, with an elevation differential of 14 meters. The lock is suitable for vessels up to 9,000 tonnes. Its installation reduces the traffic of the first three locks as these have reached a saturation point given the ever-increasing traffic and their capacity for vessels of 2000 tonnes maximum.

Over a period of 4 years this site has mobilized huge human and material means, including the craftsmanship of multiple subcontractors from the Liège province. The works required the on-site production of over 220,000m³ of concrete mainly made of the gravels extracted from the river Meuse during the earthworks of 1.300.000m³ (cut and fill). The concrete was reinforced with 15,000 tonnes of steel and required 200,000 m² of formwork.

BESIX, backed by its experience in large Civil Engineering projects here and around the world, finalized this site within the deadline period while also coordinating the works of the electromechanical equipment of the lock (which it was part of through BESIX Sanotec).
