Presentation and key elements
What is it?
Soil mixing is a technique that mechanically mixes the in-situ soil with a cementitious binder. In this method the soil is sheared using specially designed augers or mixing tools, and a binder is injected and mixed with the soil to create a strengthened soil profile. Solid blocks can be formed by overlapping columns.
When and why use it?
Soil mixing is used for a wide variety of applications: controlling and reducing settlement under structures, increasing the bearing capacity of the soil, ensuring stability, reducing liquefaction risk, mass stabilisation, reducing earth pressure behind retaining structures, blocking groundwater, and increasing lateral reaction around foundation piles.
It is a very flexible technique that can be applied to many different applications Binder dosage and mixing parameters are selected according to soil characteristics and specifications to be achieved.
💡 Menard’s tip
Menard has proven over the years that soil mixing can be utilised across a wide range of soil types. However, caution is advised where obstructions are expected.
