Good viscosity and compatibility, the waterproof membrane can satisfy in different parts of the construction or other use of composite materials. Construction methods--hot melt,cold and hot adhering methods could be adopted to adhere sheets and substrates,or different sheets.while constructed with hot melt method, the thickness of membrane must be over 3mm,if constructed with cold adher ing method,the thickness of cold adhesive must be 0.5-1mm. Substrate preparation--waterproofng substrates shanll be flat,solid,and be dried sufficiently.Detail structures shall meet requirements of related stipulations and designs. Waterproofing layer--there are two kinds of structures of laminated and single layers ,for laminated layers,thickness of each layer shall be not lower than 3mm,with complete adhesion between each other;for single layer,thickness of the single layer shall not be lower than4mm. overlapping--overlapping between sheets shall be completely adhered,with 80-100mm width of jointed area. Vertical surfuce ends==fasten with metal battens and bolts,coat special sealant in all edges. Protection isolation layer construction---protection isolation layer shall be set on the exterior surface of waterproof layers according to related stipulations and designs,if use shale or mineral grain coating surfaces as exposed waterproof layers,additional protective layer could be omitted;isolation layers shall be set between waterproof layers and rigid protective layers. |
