摘要
The invention pertains to a reinforced covering material, comprising a reinforcement layer with apertures therein, and a polyurethane-based layer comprising 20-100% of thermosetting polyurethane, based on the weight of that layer, which polyurethane-based layer is arranged at least one side of the reinforcement layer and extends through the apertures. It may be used to provide weather- and water-proofing in construction materials, e.g. as lead flashings or in/on roofs, bridges and tunnels.
