Specialist ground remediation and soil stabilisation company Deep Soil Mixing Ltd has helped with the completion of a £6.5 million project to strengthen the hillside, improve drainage and boost flood resilience at Scout Road in Mytholmroyd, West Yorkshire, for client Calderdale Council. Deep Soil Mixing Ltd used their controlled soil mixing technique to transform the challenging site, using Deep Soil Mixing Ltd’s Allu bucket on a 20-tonne excavator. They stabilised the soil and locked in the asbestos fibres contained in the ground, which proved to be an economical and practical solution. “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 methods including piling,” said Colin Critchlow, director at Deep Soil Mixing Ltd. The company also installed a King Post Wall at the bottom of the affected area to create an anchor point for the stability of the slope. This was to ensure that any slips during the soil stabilisation works on the upper slope would be contained and would not affect the surrounding buildings and services. It also created a stable working platform from which the mixing operation could commence. In order to work with and dispose of asbestos to commence work on thee 3,500 m2 site, the workforce was equipped with full face masks and disposable clothes, as well as decontamination when exiting the working area. The project proved to be challenging from both a technical and health and safety perspective. “The completion of work at Scout Road is a key milestone in Calderdale’s recovery from the floods. Along with borough-wide flood alleviation schemes and a range of natural flood management projects, it’s a powerful example of our determination to build resilience against extreme weather events. It has been carried out to the highest possible standard and many of the techniques used have shown real innovation, leading to improved protection for over 80 nearby homes and around 30 non-residential properties,” concluded Cllr Barry Collins, Calderdale Council’s cabinet member for regeneration and economic strategy.
A recent soil mixed road project by Deep Soil Mixing Ltd has won the Environmental and Sustainability Award at the Institute of Highways Engineers Mercia Brand Awards. The project was carried out for contractor Kier Living and consulting engineers Patrick Parsons Ltd. The award was presented to the multi-disciplinary consulting engineers Patrick Parsons Ltd for the deep soil mixing works below the adoptable highway at Harrowby Road, Bilston. The site was being redevelop by Kier Living to provide residential properties. However, the landfilled made ground below a section of the road was of such poor quality that CBR values (CBR = California bearing ratio, a test for the mechanical strength of the natural ground) were almost non-existent. Therefore, the local Highways Authority and Severn Trent would not adopt roads due to the low ground quality. Patrick Parsons Ltd and Deep Soil Mixing Ltd provided a suitable ground improvement method using DSM’s double rotational mixing head to soil mix the ground as well as improving the waste classification of excess materials post treatment. By mechanically mixing the existing soil with a cementitious binder, the new geotechnically modified material provides greater ground stability the area can be used for residential properties. Additionally, this method also proved to be much more sustainable and environmental friendly than the previously planned method of removing the low quality ground and replacing it with imported granular fill. Besides that, it also had the advantage of being quicker a more cost effective. Colin Critchlow, Director at Deep Soil Mixing Ltd, comments: “We are very proud that the Harrowby Road project has won the IHE Mercia Award for environmental and sustainability project of the year. That is the ethos of what Deep Soil Mixing Ltd and the solutions we offer is all about, environmentally friendly and sustainable solutions.”
