Menard Vacuum™

An Industry First for Stabilizing Poor Soils

Menard Vacuum™ is a type of atmospheric consolidation system that is used to speed up the consolidation of highly compressible soil types. The system process consists of creating a negative pressure under a completely airtight membrane laid over a soil area. This generates atmospheric pressure on the soil, equivalent to the pressure exerted by a 3-4m embankment.

How it Works

The Menard Vacuum™ innovative technique substantially reduces consolidation time thanks to early pre-loading as soon as the system is in place and without risk of any ground failure. In addition, the isotropic nature of the Menard Vacuum™ load and the increase in cohesion created by the vacuum between the horizontal drains and the membrane results in a powerful stabilizing effect on the soils.

Advantages

Accelerates the consolidation of soils
Rapid installation: shorter project timelines
Significantly reduces soil handling by eliminating pre-load

Technical details

  • Compressible soils 
  • Clay soils 
  • Fill soils 
  • Tailings and dredged materials 
  • Treat soils up to 40m deep 

The process consists of installing both a vertical and horizontal draining system combined with a vacuum-type of pumping system underneath an airtight membrane. The area is then sealed, completely concealing the membrane into a network of peripheral trenches. By installing vertical and horizontal drains directly connected to a pumping system and an airtight membrane, soil mass is pressured under the vacuum, and water is expelled.
