Menard Vacuum Consolidation
what it is:
A proprietary system that used the atmospheric pressure to preload and rapidly consolidate soft saturated fine-grained soils.
how it works:
A network of vertical and horizontal vacuum transmission pipes are installed under an airtight membrane. The air below the membrane is evacuated producing a vacuum under the membrane and a pressure on the soils equivalent to 14 ft of fill material
why it’s used:
Control the rate and magnitude of loading and settlement and save significant time over other consolidation methods. Eliminate the risk of failure under additional loading of permanent construction, and reduce the amount of surcharge material needed.
