Environmental benefits <\/i>\n
<\/h2><\/div>
\n- Fewer natural resources are consumed,<\/strong> such as water, cement and aggregates, which are replaced by the soil in place.<\/li>\n
- Little or no spoil is produced,<\/strong> so less material has to be disposed of and less CO2 is emitted (due to transport).<\/li>\n
- Contamination present in the soil is neutralized<\/strong> by treating it in situ with a binder.<\/li>\n
- No displacement of land (excavation, dredging, etc.),<\/strong> so less risk of pollutants circulating in natural environments.<\/li>\n<\/ul>\n

How to use the Colmix\u00ae process ?<\/p>\n
<\/h2><\/div>
The single tool can be used on any pile machine of sufficient power. Multiple tools require machines equipped with a special rotating head.<\/p>\n
During the drilling phase, the tool breaks down the structure of the in-situ soil. A cement grout is injected during this phase to facilitate the tool\u2019s penetration and above all to incorporate the required quantity of binder to achieve the end properties of the mixed-soil column.<\/p>\n
Most of the mixing of the soil-cement material is therefore carried out during this phase. Mixing of the materials is refined during the auger extraction phase.<\/p>\n
Intersecting columns are built according to the same principle, by drilling into pre-constructed columns (either fresh or once they have already started to set).<\/p>\n

Execution controls and monitoring<\/p>\n
<\/h2><\/div>
Implementation of the process is accompanied by real-time monitoring from a screen located in the cabin, allowing the operator to comply with the execution instructions and recording the main operating parameters during construction of each column.<\/p>\n
Quality control also involves taking samples of the fresh soil-cement mixture, most frequently by deep sampling.<\/p>\n
