Soil Treatment with Mixed Pulverised Binding Agent
Most often the binding agents are cement and lime, which can be spread separately, however, special premixed additives became available for spreading in a single pass.
Soil Treatment with Liquid Chemicals
As the most un-preferred characteristics of soil are generally related to water content, these chemical additives usually aim to change unwanted behaviour when soil and water interacts. These chemicals can prevent chemical binding of the absorbed water or in other cases they can provide for necessary water content needed for virtual cohesion.
Successful utilisation of these chemical additives strongly depends on the chemical characteristics of soil particles and the reaction of the chemical additive to them. Nevertheless, widespread use of these chemical agents is limited by their price and relative unavailability.
