<p>The sealing membrane (1) intended to be directly exposed in an external medium, comprises a mass of bituminous compositions (2) formed in a continuous layer, a layer of filamentous/fibrous material embedded in the mass, a lateral strip (5) along a length of the membrane, and sheets. The bituminous composition has a bituminous mixture containing minerals, and bitumen mixture with a polymer elastomer styrene ethylbytylene styrene. The sheet is embedded in the mass of the bituminous composition, which is placed near a side of the membrane (4) intended to be visible or exposed. The sealing membrane (1) intended to be directly exposed in an external medium, comprises a mass of bituminous compositions (2) formed in a continuous layer, a layer of filamentous/fibrous material embedded in the mass, a lateral strip (5) along a length of the membrane, and sheets. The bituminous composition has a bituminous mixture containing minerals, and bitumen mixture with a polymer elastomer styrene ethylbytylene styrene. The sheet is embedded in the mass of the bituminous composition, which is placed near a side of the membrane (4) intended to be visible or exposed. The sheets consist of a fine veil (3) with open work structure and without preferential direction of resistance to the constraints. The fine veil is formed of filaments and/or fibers material, which is resistant to ultraviolet rays. The membrane forms covering braid, which is deprived of sheet/veil. The bituminous compositions comprises two different compositions divided in two stratified adjacent layers with a first layer forming non visible/not exposed side of the membrane after its installation and a second layer forming visible and exposed side of the membrane after its installation. The first and second layers are constituted by the bituminous mixture in which the second layer is compatible with the first layer. The veil forms a sheet such as a non woven, mesh, woven or analogous structure in which the veil is embedded in the second layer. A median plane of the veil is placed at a distance of 0.1-0.25 mm of the side of the membrane. The second sheet of the filamentous/fibrous material is embedded in the mass of the bituminous composition and forms a reinforcement framework extending in width and length wise on all the membrane surface. The veil forming first sheet is laid out between the second sheet and the visible/exposed side of the membrane. The second sheet forming reinforcement framework is placed and embedded in the second layer. The sheet is situated considerably to an interface of two layers while impregnated at the same time by the bituminous composition of the first and the second layers. The two sheets are connected between each other by chemical and/or mechanical bonding points. Independent claims are included for: (1) a sealing system; and (2) a method of fabricating a membrane.</p> |
