Streamlined Efficiency for Masonry Construction

The SureCav Cavity Spacer System is an innovative and efficient solution designed to simplify your masonry building projects. Crafted from lightweight polypropylene, this panel fits perfectly within the cavity, enabling the construction of an outer skin using stone, slate, brick, or flint—without the need for an additional block leaf. This reduces material use and speeds up the build process.

Made from 100% recycled polypropylene, SureCav is built to last the lifetime of your structure and holds BBA certification, offering trusted performance and peace of mind. It acts as a reliable barrier against wind-driven rain, ensuring the cavity remains dry and free from mortar contamination.
