Chemical soil stabilisation eliminates the need to replace existing soil on a large scale as the soil characteristics are improved according to the needs of the project being undertaken.
Surface stabilisation with binder and where necessary filler material may be used in various infrastructure projects, for example:
Surface mass stabilisation is a method for improving characteristics of weak soils (ex. peat, lime lake, clay and silt) through adding binder. Enhanced soil columns or blocks, panels, etc. of the columns are created (see drawing below). The result is a reduction in load caused surface sinking and an increased surface stability.
Deep stabilisation is used in places where weak soil thickness is < 25 m. The column diameter is usually 50...100 cm.
