Slurry Wall is a ground improvement technique that uses non-structural underground barriers to build cut-off walls to prevent the flow of water.

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.

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

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

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

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