| Use advice for data set | The approach is “cradle to gate” (A1–A3) with modules A4 - A5, C1–C4 and module D. The production process starts from raw materials, that are purchased from external and intercompany suppliers and stored in the plant. Bulk raw materials are stored in specific silos and added automatically in the production mixer, according to the formula of the product. Other raw materials, supplied in bags, big bags or tanks, are stored in the warehouse and added automatically or manually in the mixer. The production is a discontinuous process, in which all the components are mechanically mixed in batches. The semi-finished product is then packaged, put on wooden pallets and stored in the finished products warehouse. The quality of final products is controlled before the sale. |
| Technical purpose of product or process | Resfoam S is fluid, two-component polyurethane injection resin for waterproofing concrete and rocks structures subjected to water seepage. Some application examples are: - Waterproofing tunnels subjected to water seepage through cracks or cold joints between ashlars. - Injection and waterproofing with use of injection hoses. - Waterproofing wells or hydraulic structures that leak water through joints or cracks. - Repairing cracks in dams, canals, and crest gates, even under water bed. For more information see the TDS (Technical Data Sheet) on Mapei AS website (www.mapei.com/no). |
| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |

| Technology description including background system | Resfom S is a two-component polyurethane injection resin based on a unique mix of isocyanides, polyols and additives. Resfoam S reacts in contact with water, and forms a waterproofing stable semi-rigid foam. Resfoam S reacts also in case of no water present, and forms a flexible injection material. Resfoam S does not contain any halogens or phthalates. Resfoam S complies with the principles defined in EN 1504-9 standards (“Products and systems for protecting and repairing concrete structures. Definitions, requirements, quality control and conformity assessment. General principles for the use and application of systems”), and the requirements of EN 1504-5 (“Concrete injection”). |
