| Abstract |
This study was in progress with the object of that prevent a crack, a weakness of the membrane method effectively. To accomplish the purpose of this study, a sand was went to the bottom of urethane membrane for isolation with adherend as the sheet-waterproofing method. If that paint the admixture of an urethane and a sand, a sand was went to the bottom of urethane membrane with the lapse of time. The sediment layer of sand was made into the absorbent layer of concrete shrinkage. An area of this study were follows ; ? Relation of width and depth of crack in the sediment layer of sand ? Necessary thickness of the sediment layer of sand and urethan ? The amound used of sand and urethan. ? Viscosity of urethan and sedimention speed of sand ? Adhesion of the sediment layer of sand to ground |
