Dewatering study for the Filature du Rabot in Ghent

An underground parking had to be realised with an excavation down to 6 m depth. The excavation was located in the middle of a residential area with possible risks of subsidence damage. Just next to the site is a park, of which the natural groundwater level cannot be disturbed. To complicate the dewatering even more, a VOCL contamination was present underneath the excavation area. By a combination of recharge wells, cutoff walls and irrigation, the influence of the dewatering could be reduced to an acceptable level.
