Description
Greenstreak Model 646 is a 9 in. flexible PVC flat ribbed waterstop used to form a watertight diaphragm at non-moving construction joints in cast-in-place concrete. When embedded across the joint it prevents the passage of liquid, and its ribbed profile mechanically locks the waterstop into the concrete on both sides. Suitable for potable water contact per NSF/ANSI Standard 61.
