Reinforcement

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

Dynamic replacement is a ground improvement technique that reinforces fine grained soils with a network of dynamically pounded pillars.

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.

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

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

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”.

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.
