2mm /3mm/4mm/ Sbs/APP Waterproof Material for Roofing/Building

1>Description
SBS/APP modified bitumen waterproof membrane is widely used in
Industry waterproof, civil construction roofing and underground waterproof.
SBS modified bitumen waterproof membrane is specially used as waterproof
Material in cold area.
APP is suitable for areas of high temperature and of strong sun-shine. They possess good tensile strength, elongation rate and size
Stability whichcould be well suited the substrate distortion and crack.
They are also good performance in impermeability, anti-puncture, anti-broker, anti-resistance, anti-erosion, anti-mildew, and anti-weathering.


2>Construction Points
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 adhering method, the thickness of cold adhesive must be
0.5mm~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 8-
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 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.
