POLYCLAY WATER STOP is specially formulated multiple composite water stop which swell upon contact with fresh and salt water.
It combines the strength & toughness to replace conventional water stops and can be applied without split forming or splicing as required with conventional water stops.
Its self healing ability is formed upon reacting with the leaking water to form a tight pressure seal when placed in a confined condition within a concrete cold joint.
Typical Applications
 It is applied in non moving concrete joints and between precuts concrete structures of
Manholes & Septic Tanks.
Box culverts &water structures.
Water & Waste water concrete pipes.
Foundations, slabs &retaining walls.
Underground parking garages.
Concrete storage tanks & tunnels.
Replacing conventional water stops.
Product Features
 The expansion properties engineered into 
Reduce the internal pressures created from traditional clay based expanding water stop.

Guide for Application
 POLYCLAY WATER STOP  used in poured in place concrete structures:
- Carefully brush off all dust and debris and apply a coat of an appropriate POLYCLAY WATER STOP  primer to the area where the POLYCLAY WATER STOP    has to be placed on the standing structural member
 - Using moderate hand pressure with the heel of the hand, press a continuous bead of POLYCLAY WATER STOP  firmly into position on the standing structure. Check to be certain that the sealant has bonded to the primed area.
- Peel the protective backing from the exposed side of the POLYCLAY WATER STOP. Knead the overlapped ends together to form a continuous uninterrupted gasket - Pour the concrete structural into position.
NOTE: When installing
POLYCLAY WATER STOP  on poured in place structures, always remember the following consideration:
- Place POLYCLAY WATER STOP  so it is within the outer 5Cm.of any vertical or horizontal construction joint. This usually occurs on the inside edge of the rebar extension.
If a keyway is formed, place POLYCLAY WATER STOP  into the formed keyway area. 
- Always use appropriate POLYCLAY WATER STOP  Primer Product to avoid displacement of the POLYCLAY WATER STOP  during concrete pouring.
- It may be necessary to utilize masonry nails to hold the water stop in place on vertical surfaces.
When masonry nails are used, they should be placed approximately 30cm.apart..
