2.3 Operating conditions: 2.3.1 Review drawings before construction, prepare roof waterproofing construction scheme, and conduct technical disclosure.
Construction Preparation 2.1 Materials and Requirements: 2.1.1 Synthetic Polymer Roll Material: 2.1.1.1 Ethylene Propylene Monobutyl Rubber Waterproof Roll Material Specification: Thickness: 1.2mm, 1.5mm, Length: 20m, Width: 1m; Technical performance: see Table 10-9 Performance of EPDM butyl rubber waterproofing membrane Table 10-9 2.1.1.2 Chlorinated polyethylene rubber blended waterproofing membrane.
The waterproof layer can only be constructed after passing the inspection.
Disclosure content: Construction scope of waterproof layer for roof using synthetic polymer waterproofing membrane 1 This process standard is applicable to the construction of waterproof layer for roof using synthetic polymer waterproofing membrane.
The storage and operation shall be kept away from fire sources to prevent accidents.
Haina Sichuan, forge ahead.
2.3.3 The gradient of the base layer should meet the design requirements, and there should be no defects such as hollowing, cracking, sanding, peeling, etc; The moisture content of the base layer should not be greater than 9%.
2.1.2 See Table 10-12 for the selection of supporting materials for synthetic polymer waterproof coiled materials.
Before the construction of the waterproof layer, the surface of the base layer should be cleaned, and the base layer should be inspected and accepted.
Only by making yourself stronger can you truly hold up a piece of sky.
