Sbs Waterproof Membrane

Product Description

Type: Waterproof Roll Material Material: Modified Bitumen Ceiling Tile Type: Fiberglass Ceilings Function: Waterproof Color: Black Trademark: hongyuan Specification: 3mm*1m*15m HS Code: 68079000 Ceiling Tile Shape: Roll Thickness: 3.0mm Surface Treatment: Film Coated Certification: ISO, MSDS, CE Usage: Outdoor Transport Package: Pallets Origin: China SBS/APP Modified Bitumen Membrane
Sbs Modified Bitumen Membrane is made by saturating the base in bitumen, or thermoplastic elastomer (such as styrene butadiene-SBS), reinforced with polyester or fiberglass, finishing the upward face with fine sands, mineral slates(or grains) or polythene membrane etc.
App Modified Bitumen Membrane is made by saturating the base in bitumen, or thermoplastics (such as APP,APAO,APO), then covering double faces with thermoplastic elastomer (SBS) and last finishing the upward face with fine sands, mineral slates(or grains) or polythene membrane etc. while downward face with fine sands or polythene membrane.
Characteristic
Good impermeability. Possess good tensile strength, elongation rate and size stability which could be well suited the substrate distortion and crack.SBS Modified Bitumen Membrane is specially being applied in the cold area with low temperature, while APP Modified Bitumen Membrane is applied in the hot area with high temperature. Good performance in anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, anti-weathering. Construction is convenient, the melt method can operate in four seasons, joints are reliable

Construction Points
Construction methods--hot melt, cold and hot adhering methods could be adopter 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 adhering method, the thickness of cold adhesive must be 0.5-1mm.
Substrate preparation--waterproofing substrates shall 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 than 4mm.
    Overlapping--overlapping between sheets shall be completely adhered, with 80-100mm  width of jointed area.  
Vertical surface 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 sheets or mineral 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.
Attentions for Construction
Construction shall not be carried out be carried out in rain,snow or over 5 degree wind weather.
There shall be sufficient safety protective facilities in construction site,place firefighting devices according to stipulations.
Installation Sketch point
Clean the substrate using broom or high pressure dusty cleaner.
Apply primer
Heat membrane bottom using a high temperature flame gun.
Push forward while the primer and membrane oil melted.
Use roller to push hard the membrane surface to ensure it stick firmly.
