STABILISATION & MODIFICATION
Soil stabilisation and modification is now the preferred solution for transforming unsuitable or marginal soils into a useful construction material. The process converts waterlogged clay bearing or contaminated land into a solid working platform, fast.CON-FORM is leading the way in this field, allowing customers to benefit from an efficient and reliable alternative to conventional construction methods.
One major benefit is the ability to use existing site materials by improving the material characteristics to achieve the desired strength and stability. This reduces both the disposal of waste material and the importation of costly replacement materials, which in turn significantly reduces the need for vehicle movements. As an example, site arisings and old pavement surfaces can be crushed and mixed with cement and then rotovated into the ground to produce a CBM (cement bound material) as a cheaper and mechanically superior alternate to crushed rock Type 1 sub-bases.
Following a detailed analysis of the area to be treated, a range of binders is incorporated, dependent on the characteristics and contamination of the soil being treated. The addition of lime, cement, slag, and PFA enables us to develop 'designer' soils to meet the customer's end needs.
The stabilisation reaction is temperature dependent and will continue as long as residual calcium remains in the system. It is possible for the process to continue in excess of 10 years after the first mix.
Type of works ideal for stabilisation include the improvement and modification of bulk fill materials quickly and effectively, the drying out of waterlogged sites, stabilisation of materials for capping and sub-base, and the forming of in-situ CBM's.
CON-FORM operates a fleet of spreaders including three state of the art integrated spreader/rotovators. These units introduce the binding agent to the soil whilst in the mixing drum, helping to reduce airbourne particles. The integrated units are generally used on environmentally sensitive sites but there will be cases where other equipment will have to be used due to the type of material to be treated. Where non-integrated stabilisation units have to be used, CON-FORM will work with the local community to minimise any inconvenience caused by its operations.
