Saving contractors thousands-of-pounds.....
In many parts of the UK large areas of land are unsuitable for construction because the soil is too wet, too cohesive or simply too weak to provide a stable base.
For many years it was common practice to remove unsuitable soil and replace it with new material. However this is an increasingly costly approach and construction companies are also under increasing pressure to use more sustainable construction methods.
See below, how soil stabilisation could be the best solution for your construction project.
Soil Stabilisation Benefits
Soil Stabilisation is the process of adding select binders to site won soils to reduce moisture content to 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, allowing disposal and aggregate import to be significantly reduced.
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)
Soil Stabilisation is used on high profile projects, including the Channel Tunnel and Heathrow Airport.
• Waterlogged or winter working platforms
• Brownfield sites
• Piling mats
• Embankment stability
• Haul road construction
• Car parks
• Foundations for floor slabs
• Highway pavement construction
• Airport runways, taxiways and aprons
Our varied machinery allows us to tackle the most complex Soil Stabilisation projects. Configurations include:
- Wirtgen S-Pack 250i
- Separate, Integrated and Tractor Towed
- Mixer and Spreader means
We have high production capabilities, as well as the opportunity to overcome issues of access, or environmental problem such as dust control.
Our specially formulated coarse and powder graded range of lime binding products offer high water absorption and consistent purity for all soil treatments.
In Clay bases, cement combined with our selection of Ground Granulated Blast Furnace Slag (GGBS), Pulverised Fly Ash (PFA) and recycled aggregates, will provide optimal densities to offer a strong load bearing platforms.
