Soil stabilisation a general term for any physical, chemical, mechanical, biological or combined method of changing a natural soil to meet an engineering purpose.
Stabilisation makes soil more stable by reduction in the permeability, compressibility and with increase in shear strength; it makes the soil more stable thus enhancing bearing capacity of soil.
These new stabilising techniques create hydrophobic surfaces and mass that prevent road failure from water penetration or heavy frosts by inhibiting the ingress of water into the treated layer.
Soil Stabilisation can dramatically reduce lorry journeys for the removal of the existing soil which is already present on a site, to offsite movements by up to 85%. Not only does this have a benefit to the environment by significantly reducing the carbon footprint, to retain the original soil in situ eliminating the need for mass excavation and significantly lowers the quantity of aggregate import, it also has a big impact of cost benefit
