Defence Barriers

Product Information & Features

Made from a corrosion resistant, hot dipped galvanised steel gabion, and heavy duty, non-woven, permeable polypropylene fabric liner which is UV and flame resistant.

Defence Barriers can be filled with minimal manual labour and resources required, and offer significant advantages over traditional sandbags in terms of cost, time and labour, which make them ideal for flood prevention and emergency flood response.

Defence Barriers have multiple uses as flood and retaining barriers, along with being more cost effective and requiring less fill for stop banks and flood diversions. The heavy-duty fabric liner contains the fill and prevents additional contribution of contamination spread
