Split Face Block Wall Caps

Our soft lead caps are installed over a sealant-filled joint. They act as a protective shield, reducing the sealant's exposure to UV rays, weather, and physical stress. The flexible lead also moves with the building, preventing the joint from checking or opening up, which is a common cause of moisture penetration and sealant failure.

Absolutely. Our system is a preferred solution for historic preservation and is specified in the U.S. General Services Administration (GSA) Historic Preservation Technical Procedures. It has been used to protect numerous national landmarks, ensuring that restoration work is both durable and historically appropriate, preserving the integrity of the structure.

The caps are made from a soft lead composition. This material is chosen for its unique properties: it is highly flexible, durable, and resistant to corrosion. Its low elastic modulus allows it to 'creep' and adapt to building movement without failing, providing a permanent, weather-resistant seal that protects the underlying sealant.

Type A is a flat cap designed for joints between masonry units that are on the same plane, such as the top joints of copings or across a window lintel. Type B is a 90-degree cove cap designed for right-angle joints, such as where a horizontal coping meets a vertical parapet wall or around the perimeter of a window frame.

Yes, our lead caps can be painted to match any aesthetic requirement. While they naturally oxidize to a neutral grey that blends well with most masonry, painting is an option for specific color schemes. This versatility allows architects and builders to achieve the desired look without compromising on protection and durability.
