Retaining Wall Caps

While retaining walls can be capped with various materials like concrete or stone, protecting the joints is key. We offer two types of joint caps: Type A (Flat Cap) for same-plane joints on top of copings, and Type B (90° Cove Cap) for right-angle joints where the coping meets a vertical surface like a parapet wall.

The top piece of a retaining wall is typically called a cap, coping, or capstone. Its purpose is to finish the wall aesthetically and prevent water from entering the wall's core. Our products are not the cap itself, but a patented system designed to protect the sealant in the joints between these top coping stones.

WEATHERCAP is made from a soft lead composition. This material is chosen for its unique properties: it is highly flexible, allowing it to creep and adapt to building movement without tearing or shearing. This ensures a permanent, elastic seal that protects the underlying sealant and prevents moisture penetration over the long term.

Yes, WEATHERCAP is ideal for both historic restoration and new construction projects. Certain products, like our A-2 Type A Flat Joint Cap, are specifically designed for new installations. Using our system in new builds provides long-term protection for masonry joints, extending the structure's life and reducing future maintenance needs.

WEATHERCAP protects sealant in two primary ways. First, it physically covers the sealant, shielding it from UV radiation and environmental wear. Second, its flexible soft lead construction absorbs stress from building movement, preventing the sealant from tearing or pulling away from the masonry (margin checking), which is a common point of failure.

Yes, WEATHERCAP products can be painted to match any aesthetic requirement. If left unpainted, the soft lead surface naturally oxidizes to a neutral grey color that blends seamlessly with most masonry and stone, providing a discreet and durable finish that complements the original architectural design.
