BeauDrain - Model S - Vacuum Consolidation System Brochure

The function of BeauDrain-S vacuum consolidation is based on the use of an air-tight hose. In this system, vertical drainage is only used in the compressible and sealing layers. The top layers of sand, where there is a risk of air or excess water inflow, are sealed off from the system with the aid of a thyleen hose. As a result, a vacuum can be applied to the drain. The vacuum in the drain translates into an equivalent (fictitious) vertical load at ground level. For each project the subsoil is studied carefully in order to ensure that the system will function as desired. A soft sealing layer of clay or peat must be present just below the surface.
