Description
Bituminous waterproofing membranes can be used in waterproofing projects with intermittent construction schedules, reducing phenomena such as wrinkling and blistering after membrane installation. This dataset includes major raw and auxiliary materials and energy used in the production process; however, infrastructure such as production equipment and factory construction is not included within the system boundary of the dataset. The life cycle inventory is compiled from data obtained from multiple sources. The manufacturing process of bituminous waterproofing membranes includes procedures such as bitumen heat preservation, metering and formulation, oxidation, impregnation, coating, film lamination, cooling, winding, and packaging.
Activity Description
The production activities of the product include processes such as asphalt insulation, metering and batching, oxidation, impregnation, coating, film lamination, cooling, winding, and packaging.
Process Description
Bituminous waterproofing membrane uses polyethylene film as surface reinforcement material, covered with rubberized asphalt adhesive containing active additives. It can be installed using cement slurry (wet-lay method) or applied directly using traditional techniques (dry-lay method), meeting diverse construction requirements for different projects. This product is suitable for waterproofing projects with intermittent construction schedules, and when the membrane is exposed for extended periods after installation, it helps reduce wrinkling and blistering after sheet application.
