Is there a standard for outdoor temperature when laying waterproofing membrane in winter construction?

According to the actual inspection and construction experience, the construction temperature of the coiled material is about 10℃ higher than the flexibility of the coiled material, which can be expressed by a formula, that is, the flexibility of the coiled material+10 ℃= the lowest construction temperature of the coiled material.

The above are practical application experiences, and there seems to be no specific requirements in relevant national codes.

Waterproof coiled material refers to waterproof products made of asphalt or polymer waterproof materials impregnated on the matrix, which are provided in the form of coiled material and are called waterproof coiled materials. Waterproof membrane is mainly used in building walls, roofs, tunnels, highways, landfills and other places, which can resist the leakage of rainwater and groundwater. As a leak-proof connection between the engineering foundation and the building, it is the first waterproof barrier of the whole project and plays a vital role in the whole project. Products mainly include asphalt waterproofing membrane and polymer waterproofing membrane.
