Not Sure Where to Start?

We've put together a comprehensive guide to the available Sika Greenstreak PVC Waterstop profiles.

What is PVC Waterstop?

A PVC waterstop is a flexible polyvinyl chloride profile embedded in concrete joints to form a continuous, watertight diaphragm — preventing liquid from passing through the joint between two concrete pours. PVC is the industry standard for flexible waterstops thanks to its broad design range, natural elasticity, and resistance to waterborne chemicals. Sika Greenstreak PVC profiles are NSF/ANSI 61 certified for potable water contact and meet Army Corps of Engineers Specification CRD-C 572-74, making them a trusted choice in water treatment plants, tunnels, tanks, foundations, and containment structures.

Moving Joints

Movement joints handle the flex caused by shrinkage, temperature swings, settlement, and live loads. Profiles like the ribbed centerbulb and tear web are engineered with geometry that absorbs lateral, transverse, and shear movement while keeping the seal intact — making them the right choice for contraction, expansion, and isolation joints.

Non-Moving Joints

When steel reinforcement runs continuously through a joint, movement is negligible and a flat profile is all you need. Flat ribbed, base seal, and dumbbell shapes deliver excellent sealing characteristics in slabs-on-grade, foundations, and other construction joints where the priority is a clean, watertight barrier rather than flexibility.

Retrofit

Retrofit waterstops are purpose-built for sealing joints between new and existing concrete. Unlike standard embedded profiles, they anchor directly to the existing concrete face using stainless steel batten bars and structural epoxy — making them the right tool for repair, renovation, and upgrade projects where tearing out and repouring isn’t an option.

Waterstop Selection Help from Real Experts

Not sure which PVC waterstop is right for your project? Choosing the wrong profile — or the wrong joint type — can mean leaks, callbacks, and expensive demolition down the road. We offer free, personalized consultation to help you spec the right Sika Greenstreak profile for your specific concrete joint conditions.

Whether you’re sealing expansion joints in a water treatment plant, construction joints in a foundation, or retrofitting an existing tank, our team will walk you through profile geometry, movement ratings, NSF 61 and Corps of Engineers compliance, and splicing best practices. We’ve helped contractors, engineers, and owners spec waterstop for tunnels, dams, containment structures, and wastewater facilities — and we’ll help you get it right the first time.

Beyond PVC: Our Network of Specialist Waterstop Sites

PVC is the right answer for most concrete joint waterproofing — but not all of it. We’ve built a network of specialist sites so engineers, contractors, and owners land on the exact product family the project calls for, each with deep technical content matched to the material.

RetrofitWaterstop.com covers retrofit systems for sealing new concrete to existing concrete — stainless steel batten bars, structural epoxy, and the splicing details that make tank rehabilitation, repair, and renovation projects watertight without a full tear-out.

TPERWaterstop.com handles chemical-resistant waterstop: Sika Westec TPE-R, polyethylene, and 316 stainless steel profiles built for refineries, ethanol plants, pulp mills, and secondary containment where standard PVC can’t survive the chemical exposure.
