The permeable form has the quality improvement effect of concrete surface layer. On the other hand, a wrinkle occurred at form setting works and might leave it and might be connected to aesthetic dirty at concrete surface. This cause is regarded as outputs to produce because the lack of permeable sheet hardness. Therefore we chose “permeable sheet having hardness that improved model” and in this experiment, a few kinds of different form materials were examined in the permeable form setting works and concrete aesthetic beauty and durability enhancement. As a result, slack and a wrinkle did not produce the sheet which we chose at the time of form setting works. And the durability enhancement of concrete surface layer using a permeable form having hardness is the same class in permeable form current model.
