Introduction：
This product is a kind of unbreakable asphalt waterproof
cushion which belongs to the waterproof and wet isolation
construction material area, it has excellent tensile flexibility.
It is composed by the polymer felt, tensile layer and release
layer. The bitumen compound layer is SBS modified bitumen compound
layer or rubber bitumen compound layer. In order to solve the
problem of easy breaking and weak tensile strength, we coat the
felt layer with compound bitumen layer and tensile layer. We paint
the mineral sand onto both side of the cushion to stop the
stickiness. This tensile flexibility waterproof cushion is
flexible, at the same time, it has excellent tensile strength, and
it is waterproof and moist insulation，it has very long service
time, its produce technology is simple and suitable for waterproof
project of the base, floor and roof for all kinds of
buildings.
Product Features
1. High
dosage SBS, ensure the long term service time.
2. Unique
formula ensure the SBS have a good compatibility with
the bitumen, it will guarantee the stability and stickiness in long
term service time.
3. Advanced
produce technology and equipment can ensure the quality of
membrane.
Application
1. Viaduct，bridge,
underpass, tunnel，underground，park，air station
2. Flat
roof, arch roof, cement preset roof.

Installation Instructions
(1). Double sand waterproof cushion is designed for new or
reproofing work over properly build and supported wood roof decks
or concrete roof decks with a slope of ≥*0 degrees.
(2). When they are installed over the wood roof decks, they
will be fixed with adequate felt nails; when they are installed
over the concrete roof decks, they will be fixed both with
adhesives and adequate steel felt nails.
(3). Apply them over properly
prepared roof deck, starting at bottom of roof and working across
and up.
Starter
Course
(A) Trim tabs off all
starter course double sand waterproof cushions, so sealant can seal
along the eave’s edge.
(B) Complete rest of starter course, use at least five
fasteners for each waterproof cushion, placed 2″to 3″up from the
eaves edge.
FirstCourse
(C). Apply first course, starting with a full waterproof
cushion, even with the starter course, use fasteners or adhesives
to fix each waterproof cushion.
SecondCourse
(D). Begin second course by
positioning first waterproof cushion from the end of the underlying
waterproof cushion,-with the
butt edge alignedwith the top of the cutouts in the course
below.
Third Course
(E). Begin each subsequent course by
positioning the first waterproof cushion from the end of the
underlying waterproof cushion,with the
butt edge alignedwith the top of the cutouts in the course
below.
(F). Leave about 5″(**5mm) exposure,
fasten securely and trim excess overhang at rake.
(G). each waterproof cushion will be fixed by at least five
fasteners. If the roof decks with a slope of ≥**0 degrees, more
fasteners and adhesives will be used.
