The KC Series is specifically engineered for concrete expansion joints where significant structural movement is anticipated. These external waterstops are positioned on the exterior side of the joint line, forming a continuous, flexible barrier that accommodates movement while maintaining a watertight seal against groundwater, rainwater, and other moisture sources.
Unlike internal waterstops, the KC Series is chosen when the waterproofing strategy focuses on an external barrier, working in conjunction with surface membranes, sealants, and protective coatings to ensure comprehensive joint protection.
The KC Series offers a range of profiles to suit various expansion joint widths and movement requirements, including models like KC-380x10, KC-350x6, KC-330x6, KC-300, KC-250, KC-200, and KC-150. These models provide reliable performance in demanding environments, ensuring the long-term integrity of concrete structures.

The KC Series is typically specified in projects where concrete structures are expected to undergo significant thermal expansion, contraction, or structural settlement. Common application areas include:
While internal waterstops are embedded within the concrete, the KC Series is an external solution. It is chosen when the waterproofing design mandates a visible, accessible barrier at the joint face, allowing for easier inspection and integration with external waterproofing systems. This external placement is crucial for joints experiencing substantial movement, as it provides a more resilient and adaptable seal.
The KC Series is specifically designed for external expansion joints in concrete structures where significant movement is expected, providing a flexible and watertight barrier.
The KC Series includes models such as KC-380x10, KC-350x6, KC-330x6, KC-300, KC-250, KC-200, and KC-150, each catering to different joint widths and movement requirements.
It is often used in large concrete slabs, bridge decks, parking garages, basements, tunnels, and water-retaining structures where expansion and contraction joints are present.
Installation involves preparing the joint surface, precisely positioning the waterstop over the expansion joint, securely anchoring it, and integrating it with the broader waterproofing system to ensure a continuous seal.
DV Series PVC Waterstop is a dumbbell-profile internal construction joint waterstop used in reinforced concrete structures where a continuous watertight seal is needed across movement joints.
SV Series PVC Waterstop is an internal construction joint waterstop used in reinforced concrete structures where a continuous barrier is required across a non-moving construction joint.
SO Series PVC waterstop is an internal expansion joint waterstop for reinforced concrete structures where a continuous watertight barrier is required across movement joints. The center-bulb profile is embedded centrally within the concrete pour and flexes to accommodate expansion, contraction, and shear displacement along the joint line.
