WIPO Patent Application WO/2021/177286

Kind Code:

A1

Abstract:

The present invention provides a structure protection sheet, which makes it possible to significantly reduce the work period in the provision of a protection layer on the surface of a structure such as concrete, to protect the structure for a long period, to prevent the occurrence of a blistering phenomenon associated with water vapor in the inside of the concrete, and to prevent the deterioration in adhesiveness. The present invention relates to a structure protection sheet comprising a polymer cement cured layer arranged on a structure side and a resin layer arranged on the polymer cement cured layer, the structure protection sheet being characterized by having a water vapor transmission rate of 10 to 50 g/m2･day.
