Sika Greenstreak offers flexible PVC waterstops and retrofit systems engineered to waterproof concrete joints in infrastructure, industrial, and municipal projects. Their waterstops - available in ribbed, dumbbell, flat, labyrinth, and centerbulb profiles - form a continuous watertight barrier in both moving and static joints and meet NSF‑61 standards for potable‑water applications. Engineers specify Greenstreak for dam walls, tunnels, bridge decks, vaults, and waste‑water tanks where joint integrity and durability are critical.
