It is a modified bitumen membrane consisting of Styrene-Butadiene-Styrene (SBS)modified asphalt mixed with imported chemical root inhibitor, reinforced with polyester fiber, and covered with different upper isolation materials. Waterproof membranes, surfaced with four different upper materials, are therefore divided into four types : PE film surfacing , Sand surfacing , Mineral surfacing and  Aluminum foil. Waterproofing membranes are of four different thickness: 2mm,3mm, 4 mm and 5 mm.

Packaging and transportation

SBS Modified bitumen membrane is packed in rolls with plastic bags. 

It can not be inclined or laterally drifted. Cover it with cloth when it is necessary.

Application methods

Surface preparation-----Surfaces should be dry, clean, smooth and free from any dusts, oil or loose particles. Cracks and surface irregularities need to be filled with polymer mortar.
Priming-----Before membrane laying, substrate treating agent need to be brushed evenly and completely to cover all the surface to be laid on.
Membrane laying-----For adhesion between membrane and substrate or membranes, it can use hot melt method or cold adhesion method. According to application designs and specific applied parts, it can be applied by fully adhesion method, strip adhesion method and border adhesion method.
Sealing, fixing and constraining on vertical surfaces-----On vertical surfaces, fix with metal battens and seal with sealants for membranes.
Application on protection and isolation layer-----After membrane laying, construct protection and isolation layer according to waterproof layer design.
