Dewatering and deformation test Hof ter Ede Maldegem

The excavation of an underground parking is planned in Maldegem, close to the Ede rive and an old Vivaqua collector. No deformation due to the dewatering is allowed at the level of the collector. AGT realized the dewatering study and recommended to execute the dewatering in between water retaining walls installed in the clay of Ursel/Asse or to execute a dewatering and deformation test prior to the excavation to determine the effective deformation. Under supervision of AGT a dewatering and deformation test was realized, which showed that no deformations occurred due to the dewatering. The final dewatering can be executed without retaining walls installed in the clay layer.
