Vertical drains, also known as prefabricated vertical drains or wick drains, are made up of a plastic core surrounded by a geotextile that acts as a filter to prevent clogging.

Menard Vacuum™ is used to accelerate consolidation of cohesive, highly compressible soils. The process consists in creating a negative pressure under an airtight membrane laid over the soil, which generates atmospheric pressure on the soil, equivalent to the pressure exerted by a 4 metre embankment.

Menard developed Controlled Modulus Columns in the 1990s to overcome problems of lateral confinement in highly compressible and organic soils. They are now used in all types of soil (cohesive or granular) up to depths of 30 metres or more.

Jet grouting is a ground reinforcement technique. One or several jets of fluid with high kinetic energy are used to break apart and mix the ground with a liquid cement slurry so as to form a column of “soil concrete”.

Compaction grouting is a ground improvement technique that densifies the soil by grouting under pressure a network of inclusions.

Stone columns is a ground improvement technique that reinforces the soil with a network of stone compacted columns.

Dynamic compaction is a ground improvement technique that densifies the soil by repeatly pounding it with a high energy pounder.

Soil Mixing is a ground improvement technique that reinforces the soil by mixing in situ a network of grout and soil columns.

Bi-modulus columns is a ground improvement technique that reinforces the soil by a combination of CMC and stone columns.

Vibrocompaction is a ground improvement technique that densifies the soil by shaking it with a vibro probe.
