Fix-R Pour & Roll is a strong glass fibre-based underlay mixed with oxide bitumen. It is used as an economical underlay and is mostly installed by heating the bitumen and rolling the underlay over the top. With a generous coverage of 20x1m, it is both a cost effective and time saving option.

They are fully bonded with a hot bonding bitumen at around 240°C. This process typically requires 2 operatives, one pouring the hot bitumen and one rolling the membrane into the hot bitumen.
