Waterproof material and method for applying it
 A waterproof material is disclosed herein which is obtainable by laminating many sheets of a photo-setting type fiber reinforced thermosetting resin composition comprising a resin composition containing a thermosetting resin, a photopolymerization initiator and a thickener, and a fiber reinforced material, or by laminating plural sheets of a synthetic polymer, and a waterproof application method using the waterproof material is also disclosed herein. According to the present invention, the waterproof layer can be formed on the surface of a civil engineering works or a building in a short time of about 30 minutes by a few steps without polluting a working environment. Furthermore, the waterproof layer, needless to say, has water resistance, weathering resistance, anticorrosion and substrate adhesion. In addition, it is further excellent in follow-up properties to cracks of the substrate, and walking on the waterproof layer is possible.
