GAMMAGUM P is an elastoplastomeric type membrane obtained from distilled asphalt modified with elastomeric resins and plastomeric polymers.
The reinforcement is a composite spunbond polyester.
GAMMAGUM P in its different versions is an plastomeric membrane obtained from distilled bitumen modified with plastomeric polymers (APP).
GAMMAGUM P is reinforced with a “non woven” Spunbond polyester composite fabric, stabilized with a fibreglass mat.
GAMMAGUM P 4 mm waterproofing membrane is suitable for use in applications on various roof types, whether they are insulated or not, especially those which are subject to high levels of stress such as tensile structures or metal profile decks.
GAMMAGUM P membranes are embossed with a pattern of small squares and are available with a fine grain quartz finish, to ensure that the roll unrolls correctly.
GAMMAGUM membranes have a polyethylene torch off heat sensitive film which prevents the roll sticking together and to ensure that the roll unrolls correctly. This surface is again embossed with a pattern of small squares to help the polyethylene torch off film to melt quickly and allow gases to escape, it also acts as a temperature indicator to show that the compound has reached the correct fusion temperature.
PACKAGING The top tape indicates the product type, and the lower tape the weight or thickness of the product. The rolls are supplied on wooden pallets and are held in position by a protective heat shrunk polythene covering. Each pallet has two control tickets which enable the laboratory to readily identify the characteristics of the product.
