Product Description

1. Construction waterproofing membrane
2. Bitumen membrane, anti-corrosion.
3. Many kinds of surfaces.
4. Torched applied.
 
Introduction

SBS(Styrene Butadiene Styrene) /APP (Atactic Polypropylene) modified bitumen membrane is made by saturating the base in bitumen, or thermoplastic elastomer (such as SBS, APP, APAO, APO), reinforced with polyester or fiberglass, finishing the upward face with polythene membrane, fine sands or mineral slates (or grains) or etc.
 
Naijiu ranks TOP 3 in China waterproofing industry.

Thickness3mm, 4mm, 5mm
Width1m
length10m, or on demand
BasePolyester felt
SurfacePE film, Aluminum foil, Yellow sand, Shale gravel(Schist), Colored sand
NoticeSBS modified bitumen membrane is specially applied in the cold district,
APP modified bitumen membrane is more suitable for hot district with high temperature.
NoteSelf adhesive type
Thickness: 1.2mm, 1.5mm, 2mm, 3mm, 4mm;  With or without polyester felt
Surface: PE film, Aluminium foil, Double-sided adhesive
Certificate  ISO 9001/14001


 
Applications
 
1.Roof and underground in industrial and civil buildings;
2.Bridge, subway, tunnel, swimming pool, etc.
3.Waste landfill, sewage plant, irrigation system, etc.
4.Make sure the roof deck smooth, and dry (moisture<9%), then apply the surface or roof deck homogeneously with a kind bitumen paint, till dry to start application.
There are two methods in application:
5. 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.
6. 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 slicked to roof deck.
By heating and melting method and by cold adhesive can be used in alternation in application as requested.
After application, a full serious inspection is required to sure no air bubble, no falling away, etc.  to guarantee the waterproof life.
