sbs glass reinforced polyester bitumen waterproof membrane


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.






7.5mm~10mm or as the request



1.Excellent in waterproofing anti-penetration;

2. Causing no damage to the normal growth of plants;

3.  High-strength membrane to resist water;

4. Penetration-resisting, wear-resisting, tear-resisting, corrosion-resisting,mould-resisting and weather-resisting;

5.   Good tensile strength and elongation;

6. Strong adaptability to shrinkage, deformation and cracks of substrate;

7.   Resistant to both high temperature and low temperature.


Package and transportation:

1. Membranes should be stored under dry and ventilated conditions.

2. Different types of membranes must be piled separately.

Applicable scope:

Suitable for civil building roofing, underground, bridge, parking, pool, tunnel in the line of waterproofing and dampproof, especially for the building under high temperature. According the roofing engineering stipulation, APP modified bitumen membrane could be used in the Grade I civil building and industrial building which has special waterproofing requirement

There are two methods in application:
a) One way is by heating and melting method.Heat the polyethylene film of the membrane and roof deck surface by heating and melting method to be nearly melted (not flowing),then install the membrane filly bonded to the roof deck with overlaps of 5-10cm.
b) The other way is by cold adhesive method.Pour the cold adhesive homogeneously on the roof deck, then roll the membrane to install it to be fully sticked to roof deck.
By heating and melting method and by cold adhesive can be used in alternation in application as requested.

c)After application,a full serious inspection is required to sure no air bubble,no falling away.etc. to guarantee the waterproof life.

Requirements for construction:

1.The base should be dry and clean. Do not work in the rainy or snowy day.

2.Do not work under heavy wind(above 5 grade)

3.Unsuitable for construction below 5°C

4.If it is rain or snow in the process of construction, protective measure to the laid membrane is must.

5.All the workers should put on special uniforms to keep safe when installing. There should be equipments for fire controls.


The special formulation of fire enables the membrane to be applied directly with primer. This application is named as "Torched on application".

1.Base processing: the base surface musts be clean,solid,level,dry;no grit,rift and loosing dust. For a large recess, fill it with cement mortar and then level it. Remove the protrusion and clean dust If working on base slab or lateral face,water lowering should be done.

2.Painting primer before laying the membrane, clean the dust on the surface of concrete base with dust catcher or dust-blower; then paint entirely with treatment agent of DY primer for waterproofing(for purpose of dust consolidation and high adhesive effect).

3.Heat to melt: place membrane correctly, fire torch, heat the membrane with base entirely, when the surface of the membrane is black and bright with a fusion layer, apply the membrane and press it into a solid and flat state.Before the membrane is cool, seal the edge of joint by float.

4.Requirements for lapping: There should be less than 3 layers of lapping, with the joint seams appearing as"T" type,avoid 4 layers of lapping.The width of longitudinal lapping is between 50 and 80mm,and of end-lap joint 100mm

5.Use a roller to push hard the membrane surface to ensure it stick firmly.
