Chemically stabilising the soil eliminates the need to extensively replace the natural surface as the characteristics of the existing soil are sufficiently improved to satisfy the needs of the project being realised.
The stabilisation main aims are to increase the surface strength, reduce deformation and increase rigidity in case of dynamic loads. A separate application has become the isolation and/or neutralisation of contaminated soil as well as the “locking” of polluting chemical compounds with binder into the treated surface.
Surface stabilisation through binder and where necessary filler materials can 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.
Soil mass stabilisation is a method for improving characteristics of weak surfaces (ex. peat, lime lake, clay and silt) through adding binder which results in a reduction of load caused surface sinking and increases the surface’s stability.
Mass stabilisation is mainly used in places where weak soil is 2 to 6 m deep.
