GREENSTREAK PVC WATERSTOP
Greenstreak PVC (Polyvinyl chloride) Waterstops are the benchmark for the industry and exceed standard specifications. The versatility of PVC has made these waterstops popular with specifiers and engineers. Outstanding physical properties, excellent inherent elasticity and resistance to many waterborne chemicals has made it the most widely specified waterstop material.
PVC waterstops are available in several styles and sizes. Choosing the correct waterstop begins with determining whether the joint is moving or non-moving.

Sika Manufactures Factory Fabrications
Virtually every concrete containment structure requiring a PVC waterstop is going to encounter a joint that will change direction or intersect with another joint. The lack of proper tools, equipment, and welding experience on a job site generally limits a contractor’s ability to perform these difficult waterstop fabrications in the field. When problems arise on job sites with waterstop installation, it is typically related to poor quality of waterstop directional changes (see pictures below). This is why Sika suggests, and most engineers choose to specify the use of factory-fabricated waterstop intersections produced by the waterstop manufacturer. Not only do factory-fabricated intersections promote high-quality waterstop installation procedures, but they are further provided at a cost that is undoubtedly lower than the cost to fabricate the intersection on the job site. To further encourage the use of factory-fabricated waterstop intersections, Sika has significantly increased the inventory of most popular Greenstreak PVC waterstop profiles, including all fabrication orientations (L’s, T’s, and Crosses, both Vertical and Flat orientation). These fabrications can generally be shipped the same day of order placement! To ensure that the profile you are specifying or installing is included in this list of “in-stock” fabrications, please contact Greenstreak. Now there is no excuse not to use Greenstreak factory-fabricated waterstop intersections on your next project!
