Abstract
Authors developed the repair method using geomembrane that have excellent waterproof performance. We examined the geomembrane by the accelerating tests that assumed deterioration in various exposure conditions of a accelerated weathering test, hydraulic resistance tests, chemical corrosion resistance tests, a heating deterioration examination, heat-proof and cold-proof examinations, etc., we executed the tensile test and the expansion and contraction repetition test of the geomembrane. As a result, we confirmed the following performance of the developed repair method is excellent.
