No.1 for Earthworks
Multi Service Disciplines
While tradition Bulk Earthworks techniques can be applied in most instances, developers are increasingly seeking alternative solutions to comply with Environmental regulative pressures, with Soil Stabilisation and modification processes frequently being favoured.
Widely recognised for its environmental and operational efficiencies; Soil Stabilisation is considered an eco-friendly, sustainable and cost effective method of producing durable structural ground layers that permit high bearing capacity and strong foundations.
In many parts of the UK, large areas of land are unsuitable for construction because the sub-grade soil is too wet, too cohesive or simply too weak to provide a stable base, but these issues can all be overcome with the appropriate Soil Stabilisation practices.
After initial OGL survey, volumetric calculations, trial holes, pre-construction laboratory testing and mix design, we can produce a cost comparison with the use of other construction methods to prove the financial benefits.
Soil Stabilisation Process
Soil Stabilisation is the process of adding select binders to site won soils to reduce moisture content that will enable maximum compaction, in conjunction with chemically bonding the soils to enhance strength to an equivalent or higher value than imported aggregates. This allows composite aggregate strength layers to be formed in the construction make-up.
Typically four processes:
- Lime Improvement / Bulk Modification (5% CBR)
- Capping Replacement Layer (15% CBR)
- Sub-base Replacement Layer (30% CBR)
- HBM Layer (Hydraulically Bound Material)
Benefits of Soil Stabilisation include:
- Maximise use of site materials
- Sustainable use of energy bi-products
- No costly removal of material
- Reduce aggregate imports
- Decrease transportation
- Minimise landfill
- Quicker production
