Water based emulsions reduce fire risk and burn hazards because they apply at lower temperatures than hot bitumen and typically avoid high VOC solvents used in cutbacks. This improves safety and odor control in dense urban areas and near traffic. They also simplify logistics because smaller crews can apply cold materials with less heating equipment. For waterproofing and maintenance, emulsions can be applied on complex details and large surfaces with spray or roller. The limitation is weather sensitivity, so curing and rain resistance planning is critical.
