Demonstrating environmental benefits of ground improvement

Many ground improvement methods generate much less environmental impact than other deep foundation methods, for example concrete piling. Creative use of various ground improvement methods has already generated tangible benefits to completed projects, such as the Dartford Park project in the UK. The experience gained in these ground improvement projects highlights where further use of proven and emerging technology can provide still greater opportunity to reduce the environmental impact of deep foundation systems. The present study compared the environmental impact of common methods of ground improvement against more traditional deep foundation methods to show that, using a like-for-like comparison, ground improvement methods can offer sustainability advantages. Case studies illustrate how sustainable principles have been implemented in practical ways on routine projects. Perceived barriers and constraints that may hinder realisation of greater sustainability advances are identified and some suggestions as to how these may be overcome are presented.
