摘要：
The present invention provides structure protection sheets which can not only dramatically reduce a construction period to place protective layers on surfaces of structures such as concrete but also protect structures for a long time. The present invention relates to a structure protection sheet, including: a polymer cement layer on a side facing a structure; and a resin layer on the polymer cement layer, the structure protection sheet having a thickness distribution of not more than ±100 μm.
