Stockpile and Bund

The contaminated soil is excavated and moved to another part of the site. It is spread out to around half a metre in depth on a geo-textile membrane, treated with herbicide and monitored for up to three years. The area can be surrounded by a concrete bund or root barrier, down to a depth of 3 metres. This method of treatment is usually only practical on larger construction sites.
