The AR Series is designed for concrete construction joints where the outer edge of the joint is exposed to groundwater, rainwater, or moisture from the surrounding structure. Installed on the exterior side of the joint line, the profile helps create a continuous barrier while still allowing the concrete to move.
Unlike an internal waterstop, the AR Series is selected when the waterproofing detail is built around the external joint face and needs to work together with surface membranes, sealants, and protective coatings.
For the current catalog, AR250 is the only listed product model. It is positioned as a practical single-option profile for projects that need a clear, durable, and easy-to-verify external construction joint solution.
This page is intended to support product discovery, specification review, and SEO relevance for the AR250 external waterstop detail.

The AR Series is currently represented by AR250, the only catalog model available for this external construction joint application. Project teams should still verify dimensions, tolerances, and installation detail against the approved drawing.

| AR250 | 250 | 24 | Primary profile for external construction joints in exposed or water-sensitive concrete work. |
The AR Series is typically specified where the joint line needs a durable external waterproofing solution. Common application areas include:
An internal waterstop is usually embedded inside the concrete section to protect the joint core. The AR Series is chosen when the waterproofing plan depends on a visible, external barrier at the joint face.
It is designed for external construction joints in concrete structures where a durable waterproof barrier is needed at the outside face of the joint.
AR250 is the only product currently listed for this application, making it the practical reference model for projects requiring an external concrete joint waterstop.
It is often used in basements, foundation slabs, retaining walls, tanks, reservoirs, and other below-grade or moisture-exposed concrete works.
It should be aligned along the outside edge of the joint, secured properly, and integrated with the broader waterproofing detail so it remains continuous at corners and terminations.
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.
