Condensation occurs between the concrete surface and the tarpaulin. This causes swelling and peeling of the sheet, and further penetrates the interior of the concrete to promote corrosion of the reinforcing steel. For this reason, in recent years, sheets for concrete waterproofing have been required to have not only a waterproof property but also a function of moisture permeability or a function of dispersing water vapor into the outside atmosphere.
