Stainless Steel Waterstop
Greenstreak Stainless Steel Waterstops are embedded in concrete across joints to form a continuous fluid-tight diaphragm. Greenstreak Stainless Steel Waterstop is an alternative for ozone and high temperature environments that may degrade polymer waterstops.

Fabrications
The integrity of the waterstop system is dependent on proper fabricated waterstop splices to achieve a complete fluid-tight system. All directional changes and intersections shall be miter cut and spliced by TIG welding to maintain continuity of the outside flanges and "V" expansion zone. Waterstop corners and intersections should be fabricated in Greenstreak's shop where strict quality control measures are maintained.
Installation
Proper waterstop splicing, including butting straight lengths, changes of direction, and intersections are extremely important. Waterstop should be continuous for the extent of the joint. Position the waterstop so the "V" expansion zone is centered in the joint. Support and secure the waterstop in position to limit displacement during the placement of the concrete.
