The Bennet of Anzano del Parco is a new shopping centre consisting of a basement used for parking and a ground floor for commercial use, with a square at the front for use as a car park. The basement was realized by extracting the volume under the water table level: a well point plant collected the water from the perimeter of the excavation in order to carry out the work in dry conditions. Concrete castings were made with the dry tech technique that allows to create a waterproof tank on both the bottom and the walls. Water pumping wells allowed to keep the aquifer low up to the point when the building, growing in height, created a balance of forces between the thrust of the water and its own weight.
