In the Lugano-Paradiso area, along the banks of the Swiss lake, work is underway on the construction of a residential-health complex for the elderly.
The protagonist couple put into action for the realization of this great special foundation work is constituted by the two Casagrande drilling machines C9 XP-2 and C16 XP-2, used in unison to obtain a better performance in terms of power and flexibility, given the complexity of the worksite due to the proximity to the water. To facilitate the excavation phase near the lake, a protective dam was built thanks to the insertion with a down-the-hole hammer of a series of 16-meter-long steel pipes starting from an excavation of -8m, which allowed an uncompromising hydraulic seal. We are talking about the I-C Pile technology which, unlike standard application techniques, provides for the creation of a much higher watertight wall, reaching up to 5 bar pressure. In this way, a perimeter of foundation piles was created, through jetting columns, which acts as a basis for the elevation of the building, thus blocking the entry of water.
