Welcome to SureCav
from Charlie Ayers MD

Thank you for your interest in using SureCav as the superior method for constructing
cavities with all types of masonry external finishes.

THE SEARCH FOR A BETTER CAVITY SHUTTER SYSTEM

The idea for SureCav came in the winter of 2000, I was building a large 3,500 sq ft.
timber frame bungalow with an outside skin of natural stone. To make a saving on the
contract the client had decided to forgo the use of a concrete backing-block and use
timber shutters to support the stonework.

The timber-frame constructed, we moved on to site to begin the stone work, setting
timber shutters of plywood at a height of 450mm (wall-tie height). With shutters set
around the timber frame the masons started work. By this time it was late morning. By
mid-afternoon the 450mm course had been built, no more stone could be laid and the
shutters could not be struck as the mortar was still not set, day over! Similarly, the next
day, shutters were struck, ties fitted, shutters reset and stonework continued.

As this process continued I realised we were losing a day in every three setting shutters.
Another thing was that as the shutters were struck green mortar was falling into and
contaminating the cavity and more time was wasted cleaning this up. There had to be an
easier way to do this!
