During the entire pumping operation, the Menard Vacuum™ maintains the water table at the level of the horizontal drain network. This process does not lower the water table within or around the worksite. The vacuum pumps : only the volume of water expelled by the soil during consolidation settlement the residual flow necessary to [...]
The technique is rarely used on surface areas of less than 10,000 m².
Menard Vacuum™ can substantially reduce consolidation time. Early pre-loading implemented as soon as the system is in place makes it possible. This goes without risk of ground failure. How so? The vacuum generates an “artificial beam” between the horizontal drains and the membrane. The isotropic nature of the Menard Vacuum™ load combined with the [...]
