As with many other industrialised nations, the UK has a legacy of contaminated sites, including former factories, mines, steelworks, refineries and landfills. At these sites, there can be a variety of potentially harmful substances such as oils and tars, waste metals, organic compounds, gases and mining materials that are left over from, or created by, historical activities on site.

However, there are greater concentrations of contaminants in some areas, often associated with historic industrial use and waste disposal, and in a minority of cases these may be sufficient to pose a risk to public health or the environment.

The process of assessing a site for land contamination takes time. The soil, any ground or surface water, and in some cases, gas and vapour originating from the ground, should be sampled, analysed and the hazards identified.

In recent years government policy has led to an increase of development of brownfield sites where these contaminations could be, and following a risk assessment and testing the decision is often made to contain hazards underground instead of removing or neutralising them.

In these cases it’s vital that adequate warning is put into place to protect anyone carrying out future excavations. Responding to a growing need to address this problem, Geosynthetics Limited have developed Alert®. Produced in a vivid orange colour, Alert® is designed to be clearly seen as a warning barrier. Alert® is manufactured from polypropylene tapes with excellent strength and elongation properties. Alert® excels as both a separator and contamination indicator providing a long lasting and effective solution.

The Alert® developed by Geosynthetics is the obvious choice as a contamination indicator for its practical, commercial and technical aspects. 1. It is available in large rolls of 450m2 to minimise laps and installation time. 2. Produced in a vivid orange colour, Alert® is designed to be clearly seen as a warning layer. 3. It is the most competitive bright orange contamination indicator geotextile available in the UK.

Functions:

• Warning Layer
• Separation
• Filtration
