1, construction preparation
1.1 Selection and preparation of waterproof materials
1.1.1 General use of high strength, low extension of the waterproofing membrane, the project should be combined with the actual situation, using 3 mm thick, Class Ⅱ pull ≥ 400N, elongation ≥ 5% of the jute matrix SBS modified bitumen membrane.
Node should use an additional layer of neoprene modified asphalt waterproofing coating, required solid content ≥ 43%, extension of ≥ 4.5 mm, heat degree is 80 ℃, 5h free flowing, bubbling.
SBS modified asphalt sealing material used flexible sealant, bonding of ≥ 15 mm, ≤ 4 mm ptosis degree heat.
1.1.2 Water quality requirements of materials
Membrane used in SBS modified bitumen membrane, chloroprene rubber modified asphalt waterproofing coating, SBS modified bitumen flexible sealant Dengjun must have factory qualified
