Ensures a consistent 25mm clear-cavity SureCav25 Features

Cavity protected from mortar and moisture Designed to protect

SureCav25 - the lightweight cavity-spacer system
Outstanding features that benefit the protection of
the fabric of the building and site management:

● Removes the need for a concrete block
backing wall when building with stone or
flint. SureCav25 is a lightweight
alternative that is easy to transport and
move around the site and will give you a
cheaper, quicker build.
