|
OVERVIEW |
|
|
|
ZENA-SEAL (ZSWP100)
is a water proofing membrane developed by
Zenith Rubber. The rubber membrane has 100 %
EPDM polymer content making it an ideal
choice for the water-proofing of roofs,
swimming pools, foundations for civil
constructions, soak pits for animal feed,
gobar gas plants, canals, etc. With a life
that spans 20 years ZENA-SEAL (ZSW100)
is the best choice for waterproofing
applications.
ZENA-SEAL (ZSWP100) is produced in
accordance to ASTM D4637 and ASTM 6134. The
sheet conforms to all requirements for
non-reinforced black EPDM rubber sheet for
use in waterproofing applications.
ZENA-SEAL (ZSWP100) is available
in the following dimensions: |
-
Thickness: 1mm
to 1.5 mm
-
Length: 10 mtrs
to 30 mtrs rolls
-
Width: 1 mtrs
to 1.5 mtrs
-
Packing: Rolls
are wound on 3 inch paper core with
outer surface of rolls covered with HDPE
ZENA-SEAL (ZSWP100) single ply
black membranes are light weight and have
exceptional long lasting elasticity
permitting the materials to withstand
Building movement, Expansion - Contraction
of Building surfaces, High resistance to
Ozone and weather as they are known as
“Crack-less Rubbers”, Low Specific gravity -
lightest among all rubbers, Widest
Temperature range from - 50°C to + 150°C,
Excellent Steam and Water Resistance. |
