Innovative Solution for Efficient Masonry Construction

The SureCav Cavity Spacer System offers a smart and sustainable approach to masonry building. This lightweight polypropylene panel fits neatly within the cavity, allowing the outer skin to be constructed using stone, slate, brick, or flint without the need for an additional block leaf. This reduces material consumption and streamlines construction.

Made from 100% recycled polypropylene, SureCav is designed to last the lifetime of your building and is BBA certified, giving you confidence in its durability and performance. It acts as an effective barrier against wind-driven rain, keeping the cavity consistently dry and free from mortar contamination.

SureCav is the only approved solution for creating an NHBC-compliant 25mm residual cavity, making it a trusted and eco-friendly choice for modern construction.
