The soil stabilisation process Deep Soil Mixing has undertaken on this hillside which covers approximately 3500M2 has proved to be an economical and practical solution – the soil had to be stabilised and the asbestos fibres contained in the ground locked in, before Calderdale Council can landscape the site.
Prior to commencement on site, Deep Soil Mixing Ltd undertook rigorous testing and assessment of the ground to assess its suitability for soil mixing. Laboratory tests were also undertaken using samples of the soil to be treated mixed with different proportions of a wide selection of binders to select the most appropriate mix. From these results, Deep Soil Mixing Ltd then prepared a detailed specification.
Deep Soil Mixing Ltd also installed a King Post Wall at the bottom of the affected area to create a barrier and working platform from which the mixing operation could commence.
Soil Mixing has proved to be an ideal solution for this slope stabilisation project, but it can also be used in a wide variety of other applications. In addition to the environmental advantage, stabilisation of soft soils by adding binders to reduce settlements and/or improve the stability of the land can be both a quick and cost-effective solution compared to some traditional method of piling.
As well as being suitable for some contaminated ground, if developers have a site with soft ground being present including peat and alluvial deposits, glacial till, bogs, etc soil mixing will improve the soil using the soil mixing system.
By making use of the existing ground and improving it to achieve a specified bearing capacity and shear strength, there is no need to excavate, cart away or dispose of the existing material off site and then bring in costly and bulky fill materials. It is not though, just about improving unsuitable ground but aims to turn poor quality soils into an acceptable foundation bearing strata.
What soil mixing is suitable for:
- Ground Stabilisation – Load & shear
- Land Remediation – Contaminated ground
- Retaining Walls- Cantilevered, Anchored, High Modulus
- Flood Protection – Cut-off walls
- Pipe Line Installation and Support – Sewers and services
- Canal Management – Base & walls
- Cofferdam Construction – Base & walls
- Vibration Dampening – Next to railways and construction works:
- Life Extension to Existing Retaining Walls
- Coastal Erosion – Long Shore Drift
- Repairs to Coastal Sheet Pile Walls
- Sea Bed Stabilisation
