Thermal Welding And Cement Adhesive Bonding EPDM Waterproofing
DWD EPDM waterproofing membrane is made of plasticized modified
EPDM. This is a single-ply membrane that can be used for various
applications such as roofs, parking garage, pools, basements, wet
area like the bathroom, etc.
Features of DWD EPDM waterproofing membranes.
Excellent tensile properties, high tensile strength, good
elongation performance, and strong deformation adaptability.
Good flexibility, low-temperature resistance, a wide range of
adaptation to ambient temperature.
Stability, chemical resistance, aging resistance, puncture
resistance, and long service life.
Thermal weldability and the welding seams do not need further

Application of DWD EPDM waterproofing membranes.
DWD EPDM waterproofing membrane also a wide range of applications
waterproofing membrane, it can be used in several fields of
application. Including commercial and industrial roofing,
underground structures such as basements and tunnels, the
loose-laid system under ballast or green/garden roofs, mechanically
fastened installation systems, etc
Parameters and Standard of DWD EPDM waterproofing membranes.

Installation of DWD EPDM waterproofing membranes.
Fasteners can be set in the overlapped membrane edge, and weld the
overlapped edge with a hot-air gun.
DWD waterproofing membranes can be fully bonded with DWD cement
Thermally welding installation.
Can be welded with the auto-moving welding machine to for the
smoothest appearance and excellent seams strength.
Seams of waterproofing membranes should be taken seriously enough.
Make sure all the seams are well welded. And every overlap of two
waterproofing membranes should be more than 50mm for welding.
Package and Storage of DWD EPDM waterproofing membranes.
It is advisable to store the waterproofing membrane rolls in a dry
place, sheltered from the sun in the summertime, because of the
greenhouse effect. And It should also keep the waterproofing
membrane rolls in the temperature range of -38℃ to +40℃.
Different categories and specifications should be classified and
should not be inclined or cross-stressed.
Always keep the waterproofing membranes away from a fire.
The waterproofing membranes should be prohibited from contact with
acids, alkalis, oils, and organic solvents.
