P.V.C. Water Stop
Concept
Concrete structures are only as watertight as the water stops that join them. ixxona water stop (s) stop leaks before they start………
In the concrete structure it is nesseroury as a device against possible risk of discomfiture that tends to be caused in concrete structure follows by the climatic, geo-disturbances and frictional impasse. This phenomenon results in expansion and contraction in concrete structure. This expansion and contraction results in leakage/seepage of water exposing the structure to risk of cracks or dismemberment.
ixxona p.v.c water stop joints are manufactured from specially Formulated P.V.C. Compound to resist brode spectrum of ozone, oxygen, alkalies and other aqueous born chemicals and to meet diverse. Nature of concrete lining for long term satisfactory performance when embedded in to concrete.

Read And Direction
Uncoil waterstop atleast before 12 hours prior to installation for ease of handling and fabrication |
Position waterstop to ensure proper distance. |
Care the waterstop from damage during installation. |
Clean concrete joint after first pour to remove debris and dirt. |
Center waterstop on joint, with approximately one-half of waterstop width to be embedded in concrete on each side of the joint. |
Allow clearance between waterstop and reinforcing steel of a minimum of 1.5 times the largest aggregate size. Prevent rock pockets and air voids caused by aggregated bridging. |
Ensure center bulb is not embedded at expansion joint. |
After first pour, clean unembedded waterstop leg to ensure full contact of second concrete pour. Remove laitance, spillage, form oil and dirt. |
Repeat all steps for the second pour. |
