FLAGON® TUNNEL is a synthetic membrane of plasticised PVC manufactured by coextrusion.


FLAGON® TUNNEL enables the production of a single layer membrane, each of the two surfaces being a different colour. This means that any accidental holes or tears in the material which may occur to the upper white surface during laying, become immediately visible as the black of the lower surface shows through.
