Sika Sika Greenstreak Flexible PVC Waterstop Ribbed Centerbulb 701

The Sika Greenstreak 701 Flexible PVC Waterstop is an industry-leading concrete joint waterproofing system trusted by engineers and contractors across the most demanding civil and infrastructure applications. Engineered with a ribbed centerbulb profile, this high-performance waterstop effectively prevents water infiltration in both static and dynamic joints, delivering dependable long-term waterproofing where it matters most.

Manufactured from premium-quality virgin PVC, the 701 waterstop offers an exceptional combination of flexibility, chemical resistance, and structural durability. Its ribbed design maximizes mechanical bond within the concrete, while the centerbulb geometry actively accommodates lateral, transverse, and shear joint movement — all without compromising the integrity of the watertight seal. This makes it an ideal choice for joints that are subject to thermal expansion, settlement, or live load deflection over the life of the structure.

The Sika Greenstreak 701 is well-suited for a broad range of critical construction applications, including water treatment plants, wastewater facilities, bridges, tunnels, foundation walls, retaining walls, and below-grade containment structures. Whether specified for new construction or infrastructure rehabilitation, this ribbed centerbulb PVC waterstop delivers the consistent, code-compliant performance required for heavy-duty waterproofing projects.

Key Features

The Sika Greenstreak 701 is built around a ribbed centerbulb profile that sets it apart as one of the most versatile and reliable PVC waterstop solutions available. The centerbulb geometry is specifically designed to absorb lateral, transverse, and shear movement at the joint, while the ribbed flanges create a superior mechanical bond within the surrounding concrete — delivering a watertight seal that holds up under real-world structural conditions.

Constructed from high-quality flexible PVC, the 701 waterstop offers outstanding resistance to waterborne chemicals, UV exposure, and a wide range of environmental stressors. This makes it equally dependable in aggressive industrial environments as it is in standard below-grade construction applications. The material is also rated for high-hydrostatic pressure environments, ensuring performance integrity in water-retaining and below-grade structures where hydrostatic head is a primary design concern.

The 701 profile meets NSF/ANSI Standard 61, certifying it as safe for direct potable water contact — a critical requirement for water treatment plants, reservoirs, and municipal water infrastructure. It also fully conforms to the Army Corps of Engineers PVC Waterstop Specification CRD-C 572-74, one of the most rigorous performance standards in the industry. Available in multiple sizes and configurations, the Sika Greenstreak 701 is a proven choice for tunnels, dams, reservoirs, bridge abutments, and a wide variety of other demanding construction applications.

Frequently Asked Questions

What applications is the Sika Greenstreak 701 PVC Waterstop used for? The 701 is widely specified across a broad range of civil and infrastructure projects. Common applications include water and wastewater treatment plants, tunnels, bridge abutments, retaining walls, below-grade foundation walls, containment structures, reservoirs, flood walls, and dam systems. Anywhere a concrete joint requires long-term, reliable waterproofing, the 701 ribbed centerbulb profile is a proven solution.

How is the Sika Greenstreak 701 waterstop installed? The waterstop is embedded directly into the concrete joint prior to placement, allowing the concrete to fully encapsulate the profile for a secure, watertight bond. Proper positioning is critical — the centerline of the waterstop should be aligned with the center of the joint. Split formwork is typically required for slab-to-slab, slab-to-wall, and wall-to-wall joints to ensure one half of the waterstop is cast into the first pour, with the remaining half projecting into the second pour.

Does installation require special tools or equipment? Yes. All transitions, intersections, and field splices should be heat welded using Sika’s Greenstreak Splicing Iron to maintain a continuous, watertight diaphragm throughout the joint system. Heat welding is the only recognized installation method for PVC waterstop. Sika strongly recommends factory-fabricated fittings for intersections and directional changes, as improper field fabrication is one of the leading causes of waterstop system failure.

Is the 701 waterstop resistant to chemicals? Yes. The Sika Greenstreak 701 is manufactured from flexible virgin PVC that provides strong resistance to a wide range of waterborne chemicals, making it well-suited for industrial, municipal, and environmental applications. It meets all relevant industry durability standards, including the Army Corps of Engineers Specification CRD-C 572-74.

Can the 701 waterstop handle joint movement? Yes. The ribbed centerbulb profile is specifically engineered to accommodate lateral, transverse, and shear movement at the joint. This makes it suitable for dynamic joints subject to thermal expansion, structural settlement, or live load deflection — not just static construction joints.

Is the Sika Greenstreak 701 safe for potable water applications? Yes. The 701 meets NSF/ANSI Standard 61, certifying it for safe use in direct contact with potable water. It is a trusted choice for municipal water treatment facilities, drinking water reservoirs, and other infrastructure where water quality compliance is mandatory.

What sizes and configurations are available? The Sika Greenstreak 701 is available in multiple sizes and roll lengths to accommodate a variety of joint widths and project requirements. Factory-fabricated fittings, intersections, and transitions are also available to simplify installation and ensure system integrity across the full joint layout.
