Ex Situ Soil Stabilisation
Ex Situ Soil Stabilisation

Stabilisation of soils with lime offers the following benefits; Reduction in moisture content Reduction in the plasticity of clays and production of a more friable and workable material. Increase in alkalinity to trigger cementitious reactions in pozzolanic materials. Treatment with lime of even a clay soil of high plasticity will produce a friable material suitable for further treatment...

Bentonite Clay Mixing
Bentonite Clay Mixing

Bentonite Enhanced Soils can be regarded as synthetic clay as Bentonite when rehydrated swells to 7-9 times its volume and therefore when added to soil reduces permeability. The principle application for BES has been for landfill lining however it is also an effective seal against underlying contaminants for residential or commercial developments. Ex-situ incorporation of Bentonite by use...

Bitumen Emulsion Mixing
Bitumen Emulsion Mixing

Bitumen emulsions consist of two immiscible liquids, bitumen and water, stabilised by an emulsifier. The bitumen is dispersed throughout the continuous aqueous phase in the form of discrete particles, which are held in suspension by electrostatic charges imparted to the particles by the emulsifier.Mixing cold aggregate with a bitumen emulsion produces a coating stone which may be stockpiled...

Foam Mix a unique Asphalt Technology
Foam Mix a unique Asphalt Technology

HISTORY Foamed bitumen was first patented by Prof. Lladis Cysani at Iowa University in the fifties initially to make roads for the US Army on Pacific islands using only volcanic ash. This patent used steam to foam the bitumen but was cumbersome. However many successful roads were built with this process including several in Quebec, the success and longevity of which prompted Soter Canada...
