Abstract: The present disclosure belongs to the technical field of waterproofing, and relates to a waterproof membrane, a preparation method and a construction method thereof, and a tunnel waterproof system. The waterproof membrane includes a resin sheet layer, a non-asphalt-based macromolecular self-adhesive layer and an interface bonding layer which are sequentially disposed, where the waterproof membrane has a light transmittance of ≥45%. The present disclosure provides a visual waterproof membrane, that is, light may penetrate through the membrane to make gaskets visual, and when the membrane has a light transmittance of ≥45%, it has good visibility for gaskets with warm colors such as orange and red.
