About this event

During this new presentation, Colin will give a brief introduction to soil mixing and then cover the following topics:

  • The benefits of soil mixing: why you should consider soil mixing solutions
  • The importance of lab and site trials
  • Wet or dry soil mixing? The factors involved in making the decision
  • New applications for soil mixing including how we helped in the construction of the Mersey Gateway Crossing in Cheshire

Thanks to the installation of over 1,800 soil mixed panels, specially designed to stabilise the earth around the bridge structures, we were able to accelerate construction on the project and dramatically cut costs. The Mersey Gateway Crossing is just one example of how our techniques are improving things for engineers, developers and contractors.

We’ve also worked on the following projects and will highlight how soil mixing has been used in these applications:

  • Halifax – Embankment stabilisation to prevent slippage and to deal with asbestos contamination featured in the May issue of Ground Engineering
  • Downpatrick, Northern Ireland – Pipeline stabilisation control for Northern Ireland Water
  • Housing - St Mary's Bay, Kent – Installation of soil mixed columns and a soil mixed mattress to poor ground for a housing project
  • Dover – Remediation of a contaminated site to prepare for redevelopment
  • Newcastle-upon-Tyne - The installation of a soil mixed cut off wall to prevent contamination of a River from an old tar factory
  • Newport County Council Landfill site: a project to enable compaction of clay liners on the area without reducing the natural low permeability of the silts and to prevent leaching into the underlying strata

We will be discussing projects like these, as well as some exciting new developments in soil mixing equipment that we have brought to the UK for the first time, and more importantly, how they can help engineers in complex land remediation projects.

Colin will also explore future developments in soil mixing equipment and there will also be a question and answer session at the end.
