What is Soil stabilisation? There are various ways to stabilise the soil. One is the use of lime, cement or other binder materials to geotechnically improve areas of weak soil into a construction material. This is a proven and extremely cost-effective construction technique. Basically, any soil found on site can be improved for bulk fill applications and to build roads, pavements, embankments, reinforced earth structures, railways, housings and industrial units.
When you rehabilitate natural materials, construction can be carried out with great savings on cost. It can be done quickly as well. Many years of experience has proven this technique as the only possible means for treating weak soils. It has also been endorsed by the Highways Agency since 1976. The rising costs of landfill have made this method a must for all contractors.
In situ treatment is generally more practical than traditional ‘dig and dump’ techniques. This incurs the cost of vehicle movements, landfill taxes, and the importation of virgin aggregate. Treated soils can also be manufactured to be stiffer than conventional granular materials, leading to decreased thickness designs for foundations or the next pavement layers.
Soil stabilisation can also shorten construction periods. This is because of minimising site preparation requirements, tipping and import activities. The system also enables wet ground to be dried and strengthened, ready for use. The addition of quicklime, for example, instantly dries up wet clays and allows extended working in wet conditions and into the winter.
Another great benefit is importing huge quantities of valuable resources to site, such as Type 1 sub base materials, which can be totally prevented by treating in situ soils, using fast and simple treatment process, to obtain equivalent or higher levels of structural solidity.
