Oldroyd® Xtf is a waterproof, fire resistant membrane designed specifically to protect tunnels from the detrimental effects of dripping water.
The membrane consists of a specially profiled, studded and grooved flame retardant polypropylene (PP) sheet, approximately 1 mm (40 mils) thick, onto which is laminated a high tensile strength, fire resistant woven fabric of basaltic mineral fibres.
Whilst the polyolefin sheet provides the structure of the membrane and ensures its waterproofness, the basaltic fibre fabric increases its mechanical strength considerably, as well as being of vital importance to the fire resistance properties of the membrane.
