Deep stabilisation
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:
- Road, parking lot, street, bridge ramp and railway construction;
- Developing different communication lines;
- Fence, sports ground, pool and waste dump subsoil strengthening; strengthening industrial building and warehouse territories;
- Noise barrier construction;
- Securing water body slopes;
- Reducing traffic caused vibration effects on nearby structures;
- Stabilising weak surfaces through building (micro-) tunnels.
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.
